    Abstract: This report aims to highlight the needs of integral experiments in the field of nuclear criticality safety, and to identify the available experimental facilities where such experiments could be performed. In order to identify existing experimental needs, the NEA surveyed international nuclear criticality safety (NCS) practitioners and members of the Working Party on Nuclear Criticality Safety (WPNCS). Responses were received from eight organisations and five countries (Canada, the Czech Republic, France, Japan and the United States); additional responses were also sent by four organisations in two countries (Switzerland and the United Kingdom). The survey results were examined by the WPNCS Subgroup on Experimental Needs for Criticality Safety Purposes (SG-5), which ranked the 25 identified needs in terms of priority as well as describing these needs in detail. A dedicated section of the report describes the existing proprietary experiments that might be used to meet some of the identified needs. Another section highlights some of the many facilities available to perform some of the prioritised criticality experiments.

    Abstract: The disposal of long-lived radioactive waste in a deep geological repository (DGR) is a scientifically and technically credible solution that meets the need for long-term safety without reliance on active monitoring and management. Nevertheless, it is important to assess the potential risks that may be associated with such a nuclear installation and to ensure that an appropriate regime is in place to adequately compensate third parties in case they suffer nuclear damage caused by a DGR. Therefore, countries developing or intending to develop DGRs must take into account nuclear third party liability regime(s) as long as they apply to the disposal facilities. Those regimes establish a specific legal system that deviates from general tort law principles, including strict and exclusive liability of the operator of a nuclear installation, which will have to maintain a compulsory financial security to cover its liability. Given the unusually long life cycles of such installations, this report discusses issues that concern future generations against the background of the currently applicable legal frameworks for the operation of nuclear installations, and existing technical knowledge, conscious that both will evolve. Nevertheless, it is important to identify and address potential issues regarding nuclear liability with the currently applicable legal frameworks and to set a clear framework for the applicable nuclear liability regime(s) during the different phases of operation of the DGR.

    Abstract: The radiation dose rate emitted by spent fuel assemblies is a crucial parameter within the framework of proliferation resistance, and its accurate determination is hence of paramount importance. Recent calculations have shown some discrepancies with historical results for pressurised water reactor spent fuel assemblies. To verify these discrepancies and help define a reference calculation, an international benchmark was carried out under the framework of the Nuclear Energy Agency (NEA) Expert Group on Advanced Fuel Cycle Scenarios (EGAFCS). The benchmark aimed to verify updated dose rate calculation procedures (new modelling approaches, new nuclear data, new versions of calculation codes) and share the benchmark results at the international level. The benchmark, including code-to-code verification and validation against experimental data, has shown and validated a methodology for the adequate estimation of the radiation dose rate from pressurised water reactor spent fuel assemblies (UOX and MOX) after certain periods of decay, confirming also the self-resistance of the simulated assemblies. This report outlines the exercise, its results and a series of recommendations for calculations.

    Abstract: This report compiles and shares some of the lessons learnt from implementing post-Fukushima actions related to human and organisational factors (HOF), including at nuclear facility operating companies, technical support organisations, research institutions, and regulatory authorities. It summarises a two-phase information-gathering exercise, overseen by the NEA Working Group on Human and Organisational Factors, about the requirements and guidelines that countries and nuclear licensees have adopted since the accident. The report discusses the central role of human and organisational performance in mitigating extreme external events and the management of severe accidents. It addresses the importance of validating the ability to perform these actions, and the challenges associated with performing such validations with fidelity to the conditions likely to be present during such events. The report concludes by providing four key recommendations that seek to promote greater sharing of information and the identification of best practices.

    Abstract: Knowledge of basic nuclear physics data is essential for the modelling and safe operation of all types of nuclear facilities. The de facto international standard format, Evaluated Nuclear Data File 6 (ENDF-6) format, was designed originally for 1960s era punch-card readers. The replacement of the system of codes built off this format has been recognised as an important initiative. The ability to use increasingly high-fidelity nuclear physics, coupled to accurate uncertainties, is crucial for advanced simulations. This in turn requires more detailed and accurate data, then requiring improvements to the data storage standards, simultaneously enabling robust Quality Assurance and transfer of knowledge to the next generation. In 2013, the NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC) launched a project to review the requirements for an international replacement for ENDF-6. The recommendations prompted the creation of a new Expert Group on a Generalised Nuclear Data Structure (GNDS) in 2016 that has used these requirements as the framework for a new format specification. Following rigorous international review, version 1.9 was unanimously approved as the first official published format in 2020. Since then, some 149 formal change requests were made to add new features and clarifications to the specifications, which were unanimously approved for publication in this release as version 2.0.

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: The OECD Nuclear Energy Agency (NEA) Forum on Stakeholder Confidence (FSC) acts as a centre for informed exchange of knowledge and experience regarding stakeholder interaction and public participation in radioactive waste management. It promotes an open discussion among members and stakeholders, across institutional boundaries, and between technical and non-technical actors, in an atmosphere of trust and mutual respect. As such, the FSC is, first and foremost, a learning organisation. FSC members seek to improve their own practice and institutions by uncovering practical knowledge, validating it with those most concerned and with academic feedback, consolidating knowledge and transferring lessons learnt. Since its foundation in 2000, the FSC has used and developed a set of terminology and concepts. Fostering a Durable Relationship between a Waste Management Facility and its Host Community: Adding Value through Design and Process (NEA, 2007a) included a five-page glossary of terms that appeared central to understanding the innovative concepts put forward in that major report. Then, at the 11th Regular Meeting of the FSC in 2010, it was determined that a new, extensive review of concepts and definitions would be useful in order to inform new FSC members or to elaborate future texts on decision making in radioactive waste management. The annotated glossary was prepared on the basis of a review of the full range of FSC publications across the past decade, and discussions with the NEA Secretariat and the FSC Bureau. The glossary was reviewed at the FSC-12 meeting (2011), where the FSC re-examined its key concepts, reaffirming or refining past understanding. In each entry, the key characteristics of the concept are explained and its symbolic dimension described. In some cases, references to other literature are provided. In 2018, the FSC membership decided to update the Glossary and include a new entry on added value. The concept of added value was first discussed in the report Fostering a Durable Relationship between a Waste Management Facility and its Host Community: Adding Value through Design and Process (NEA, 2015). It was recognised that although the concept has many facets and continues to evolve, a shared understanding of this concept was necessary. It is to be expected that within the coming years and through continuing dialogue, the understanding of certain concepts will evolve further and other terms will come to the fore. The FSC will continue to discuss and update its glossary to maintain it as a living document.

    Abstract: Viewed from a general, global perspective, the recognition and enforcement of foreign judgments is not the rule. On the contrary, it generally requires a specific legal basis and justification that a country accepts the rulings of courts of other states and treats them like its own decisions. The main basis for such treatment is most often an international treaty or a supranational instrument (like, for instance, the Brussels Ibis Regulation1 or the revised Lugano Convention of 20072) that provides for the mutual acceptance of foreign court decisions among the states adhering to the respective instrument. In the absence of a specific bilateral or multilateral treaty or supranational instrument, the states autonomously formulate the conditions under which they recognise and enforce foreign judgments. In this respect, some countries follow a more generous, others a more restrictive, course. But, countries do not recognise foreign judgments without preconditions;3 every country provides for a certain type of control. Some, for instance, adhere to the principle of reciprocity. These countries recognise and enforce judgments of other countries only if the other country recognises and enforces their decisions...

    Abstract: Nuclear energy is an important source of low-carbon electricity and thus plays a significant role in avoiding carbon emissions. It has the potential to decarbonise the global energy sector even further by also providing heat for industrial applications and residential heating, which both continue to run mainly on fossil fuels. More than 65 nuclear reactors around the world (about 15% of the total) with decades of experience demonstrate on a daily basis the feasibility of providing non-electric applications of nuclear energy such as district heating, desalination or other forms of process heat. In order to further reduce carbon emissions, the share of nuclear reactors used for cogeneration needs to be expanded. However, until recently the economic competitiveness of thermal energy produced by nuclear power plants has been a challenge. Not accounting for climate change impacts, heat produced by gas- or coal-fired power plants has frequently been cheaper. Yet, as fossil fuel prices rise and carbon costs are increasingly accounted for, the economics of nuclear cogeneration begin to look more favourable. A good understanding of the technical realities and economics of nuclear cogeneration, including its implications for electricity and energy systems, is essential to take advantage of this changed environment. This NEA report provides a thorough overview of nuclear cogeneration, with a view to helping energy decisionmakers and interested experts in assessing the costs and benefits of having nuclear energy provide both low-carbon electricity and low-carbon heat.

    Abstract: The transformative activity of mining has numerous economic, social and environmental impacts that can be both positive and adverse for communities, ecosystems and economies. As the uranium industry begins to address negative perceptions and legacies associated with past activities, environmental, socioeconomic and governance aspects of the uranium mining life cycle are gaining increased attention from investors, communities, regulators and other stakeholders. While environmental and human health and safety concerns often dominate stakeholder engagement programmes and public conversations about uranium operations, less public discussion and analytical research are typically devoted to the socio-economic aspects. This was the basis for this report. Through an examination of case studies from several countries the aim is to clarify how the numerous activities related to uranium mining affect various aspects of socio-economic development – including employment, supply chain investments, exports, taxes and royalties, innovation, infrastructure, education and medical care. This report’s inventory of leading practices is intended to inform public debate on uranium mine development and provide policymakers with a framework of approaches to maximise the social and economic benefits of uranium mining projects.

    Abstract: Seismic probabilistic safety assessment (SPSA) is a systematic method for examining and evaluating the risk from earthquake-initiated accidents. The significant advances in the area of SPSA since the initial publication in 2002 of Technical Opinion Paper No. 2: Seismic Probabilistic Safety Assessment for Nuclear Facilities by the OECD Nuclear Energy Agency have prompted its revision. The objective of this report is to provide the up-to-date international view on the state of the SPSA as it is currently being applied, including a description of the main elements of SPSA. While the uncertainties associated with seismic hazard and the determination of seismic failure probabilities are typically large, the inclusion of SPSA in a risk assessment results in a more complete risk picture, and thus enables more meaningful PSA applications.

    Abstract: Multiple sources of international nuclear law, including binding instruments such as the Convention on Nuclear Safety (CNS)1 and the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention),2 stress the importance of the independence of the regulator, as well as the effective separation of that regulatory body from others tasked with the promotion or utilisation of nuclear energy. Since its creation in 1974, the United States (US) Nuclear Regulatory Commission (NRC) has been characterised as an “independent agency” within the US government. One of the hallmarks of this independence is that, by law, members of the Commission cannot be removed at will by the President over policy disagreements. However, recent decisions by the US Supreme Court have declared that restrictions on the President’s ability to remove the heads of certain agencies are incompatible with the nation’s constitutional structure and are therefore invalid and unenforceable. As of this writing, these decisions have been limited to independent regulatory agencies headed by a single administrator, not multi-member boards or commissions such as the NRC. However, the Court’s legal reasoning sweeps broadly, and if the holding of these decisions were to be applied to multi-member regulatory bodies (as legal scholars predict), it would shake the organisational bedrock upon which the Commission has rested since its creation. It may also risk transforming the Agency’s public image into that of a political or promotional actor, whose activities are closely overseen by the President who is also responsible for setting energy-related national priorities and goals.

    Abstract: This report from the NEA Working Group on Human and Organisational Performance establishes a common understanding around the terms human performance (HP), organisational performance (OP), and human and organisational factors (HOF) through a simple model. The model presented illustrates the strong inter-relationship between the terms. It shows that HP includes both human activities and the results of these activities. HOF are the factors which have influence on HP in a positive or adverse manner in a given situation. They can be categorised as human-, technology- and organisation-related factors which are themselves under continuous interaction with each other. The report highlights the need for all managers to develop an understanding that the continuous application of a systemic approach is required to establish and sustain an effective management system and to foster safety culture.

    Abstract: The NEA Clay Club has been gathering the key geoscientific characteristics of the various argillaceous formations that are – or have been – studied in NEA member countries in the context of radioactive waste disposal, resulting in the publication of the Clay Club Catalogue of Characteristics of Argillaceous Rocks in 2005. This publication builds upon the 2005 NEA report by providing updated datasets for a select number of argillaceous formations presented in the previous report, as well as an expanded discussion of: the formations and their properties; the nuclear waste management organisations responsible for the implementation of the deep geological repository concept; the design concept proposed for a deep geological repository in the respective countries and rock formations; and some of the favourable properties of said argillaceous formations. A key goal of this report is to present the data in a manner that allows reasonable comparability (in both scale and methods) of the included parameters, in order to support the formal assessment and demonstration of the capacity of clay-rich formations to securely contain and isolate nuclear waste from the natural environment.

    Abstract: Following the accident at the Fukushima Daiichi Nuclear Power Plant, many countries began funding research and development on nuclear fuel designs with enhanced accident tolerance (ATFs). ATFs have improved designs, materials and performance features compared with those of the current generation of slightly enriched UO2 ceramic pellets within cylindrical zirconium alloy cladding. This report evaluates the applicability of existing fuel design and performance requirements to some of the new ATF designs (coated zirconium alloy fuel rod cladding, FeCrAl fuel rod cladding, silicon carbide fuel rod cladding, doped uranium dioxide ceramic fuel pellets, uranium silicide ceramic fuel pellets),identifies new phenomena which create the need for new or different performance metrics and design requirements, identifies data gaps and discusses opportunities for international collaborative research to fill them. A variety of new phenomena were identified for the examined ATF designs which challenged the applicability of existing performance metrics and analytical limits or created the need for new criteria. Recommendations to address these challenges are provided with the intention to inform future international research programmes and support ATF licensing.

    Abstract: The nuclear industry recognises the need for a present-day solution to the future needs in decommissioning and spent nuclear fuel and radioactive waste management. The end state for spent fuel and radioactive waste must be reached by future technical capabilities, but executable based on today’s sound legal system for decades of fund accumulation. Strictly perceived through the perspective of technical implementation, all existing nuclear facilities can be decommissioned by today’s means. Funding, however, is the issue. Each country sets up different systems to ensure financing and implementation of these projects. The adoption of various nuclear back-end strategies results from each country’s different legal system, economic ability and the national nuclear industry’s historic development.

    Abstract: One of the key areas in fuel safety is the analysis of fuel behaviour under reactivity-initiated accident conditions. Reactivity-initiated accident fuel rod codes have been developed for a significant period of time and they all have shown their ability to reproduce some experimental results with a certain degree of adequacy. However, they sometimes rely on different specific modelling assumptions whose influence on the final results of the calculations is difficult to evaluate. This report summarises three phases of benchmark conducted by the NEA between 2010 and 2019 with codes for calculating fuel behaviour in reactivity initiated accidents. Building on previous NEA reports, it provides recommendations for future research and code enhancements for safety analysis regarding reactivity accidents.

    Abstract: Reducing industrial carbon emissions is one of the most difficult challenges on the path to net zero by 2050 due to the magnitude of greenhouse gas emissions from the industrial sector and technical requirements for heat in addition to power. High-temperature gas-cooled reactors (HTGRs) are a promising Generation IV nuclear technology that can supply process heat for a variety of industrial applications. The Nuclear Energy Agency investigated the potential and limitations of HTGRs for industrial heat applications. This study reviews the technical features and development status of HTGRs as a low-carbon heat source and explores how this technology could meet the process heat requirements of different industrial processes. It revealed the potential industrial applications of HTGR heat in the near term as well as further opportunities in the medium to long term while identifying the remaining challenges for the industrial deployment of this technology.

    Series Statement: Radiological Protection
    Keywords: Nuclear Energy
    Abstract: Ten years after the Fukushima Daiichi Nuclear Power Plant accident, many lessons have been learnt that have helped improve preparedness for nuclear emergencies and awareness of the global risks that such accidents can entail. This includes a number of long-lasting, multidimensional impacts on health(including mental health and psychosocial support), the economy, and the environment. Recovery from a nuclear or radiological accident is a long, complex and resource-intensive process. To facilitate efficient recovery, it is important to establish processes and procedures during the preparedness phase to activate the resources required and to involve the relevant stakeholders at all levels. This report addresses the need for a harmonised approach towards efficient recovery management from nuclear or radiological accidents, which aims to assist countries to develop their own national plans and procedures for post-accident recovery preparedness in a harmonised manner, through the introduction of a cyclical approach.

    Abstract: With an electricity system defined by high shares of hydropower, large capacity for interconnection with its neighbours and low carbon intensity, Switzerland is well positioned to attain its objective of net zero carbon emissions by 2050. However, the exact pathway remains the subject of discussion. First, what should the shares of nuclear energy and variable renewable energies such as solar PV and wind be in the energy mix? Second, what degree of electricity trade should Switzerland have with its European neighbours? New system modelling of different energy policy choices with the Nuclear Energy Agency’s POSY model shows that all considered scenarios are technically feasible. However, relying on variable renewables alone or decoupling Switzerland from neighbouring countries could increase total system costs by up to 250%. Instead, continuing to operate Switzerland’s newest nuclear power plants alongside existing hydropower resources, while maintaining interconnection capacity at current levels, emerges as the most cost-effective option to achieve net zero emissions in 2050. Ample data and technical documentation of a least-cost mixed integer (MILP) modelling with hourly resolution are also provided in order to allow replication, extension and discussion of this study’s findings

    Abstract: Hydrogen is expected to play important roles in decarbonised energy systems, as an energy source for otherwise hard-to-electrify sectors as well as a storage vector to enhance power system flexibility. However, hydrogen is not a primary energy resource and has to be produced using different chemical processes. Water electrolysis, which uses electricity to split water molecules to extract hydrogen, is expected to become a leading solution in this context. Electrolysis will, however, only be a feasible solution if the electricity used as feedstock comes from low-carbon sources. A significant number of countries are therefore considering a role for nuclear energy in their hydrogen strategies. This report provides an assessment of the costs and competitiveness of nuclear-produced hydrogen across the hydrogen value chain and explores the impacts of hydrogen production on the overall costs of integrated electricity and energy systems. It shows, in particular, that nuclear energy can be a competitive source to produce and deliver low-carbon hydrogen for centralised industrial demand. The large scale and dispatchability of nuclear power can also improve the cost-efficiency of hydrogen transport and storage infrastructures, and reduce the overall costs of the energy system.

    Abstract: Realising the contribution of nuclear energy to achieving net zero carbon emission in 2050 will require raising significant amounts of capital at competitive rates. On the basis of work under the aegis of the Nuclear Energy Agency (NEA) – International Framework for Nuclear Energy Cooperation (IFNEC) Initiative on Nuclear Financing, this report explores a new framework for analysing the cost of capital for nuclear new build projects. Its key insight is that capital costs can be substantially lowered if the different risks pertaining to such projects such as construction risk, price risk or political risk are properly understood, optimally managed and fairly allocated. In a carbon-constrained world, the true capital costs of nuclear energy and other low-carbon generators will also be lower than customarily assumed due to their ability to offset systemic financial risk. The findings of this report apply equally to private and public investments. Governments nevertheless have important roles to play in ensuring credible net zero commitments, implementing frameworks for optimal risk management and by becoming involved as project participants, in cases where they judge that private actors do not realise the full value of a nuclear power project. This report is the first in the collection New perspectives on financing nuclear new build, highlighting complementary aspects of financing nuclear new build. Other volumes in the series address the financing frameworks and risk allocation strategies proposed or adopted for recent or ongoing nuclear new build projects, environmental, social and governance (ESG) criteria and the electricity market design, project management and incentive structures necessary for nuclear new build projects to succeed.

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: Low-level and very low-level waste represent the vast majority of radioactive waste by volume from decommissioning activity at nuclear facilities around the world, but they are only a small fraction of the radiological inventory. The availability of the appropriate waste management infrastructure, including a robust process and procedures for managing waste, waste disposal routes and an appropriate safety culture, are key components of an optimal approach to decommissioning. Recognising the important role of an effective waste management strategy in the delivery of a successful decommissioning programme, the former NEA Working Party on Decommissioning and Dismantling (WPDD) established an expert group in 2016 – the Task Group on Optimising Management of Low-Level Radioactive Materials and Waste from Decommissioning (TGOM) – to examine how countries manage (very) low-level radioactive waste and materials arising from decommissioning. This report explores elements contributing to the optimisation of national approaches at a strategic level, describing the main factors and the relationships between them. It also identifies constraints in the practical implementation of optimisation based on experience in NEA member countries.

    Keywords: Nukleare Entsorgung ; USA ; Nuclear Energy
    Abstract: Safety remains the most important factor in managing radioactive waste and spent fuel resulting from the generation of nuclear energy. General consensus has emerged worldwide that deep geological repositories are the safest option for long-lived radioactive waste, and that constructing repositories is feasible using current technologies. However, until repositories become available, radioactive waste must be managed safely and securely so that the risks posed to human health and to the environment over the long timescales involved are minimised. This report examines the predisposal phase of radioactive waste management programmes in NEA member countries for all types of waste from high-level to intermediate- and low-level waste, and spent fuel. It reviews regulations, policies, strategies and financial issues in member countries, as well as best practices both in terms of storage and transport. The report is primarily directed at decision makers with a technical knowledge of the subject.

    Abstract: The world’s nuclear power reactors are ageing, with the majority approaching the end of their planned operational lifetimes in the coming years. The adequacy of funding for decommissioning and radioactive waste management (RMW) thus increasingly commands the attention of decision-makers. This report by the OECD Nuclear Energy Agency (NEA) combines a solid conceptual framework with the insights from twelve case studies of NEA member countries to propose a new approach to the adequacy of funding that is both robust and flexible. Current funding systems in NEA countries are overall adequate. The challenges ahead however are formidable: decommissioning and RWM are moving from design to implementation, returns on assets are low and societal preferences can evolve. The very long-term nature of the solutions, in particular for radioactive waste disposal, is also not easily compatible with the economic lifetimes of the original liability holders. This requires that all elements of the system – accrued funds, expected future returns, the lifetimes of nuclear power plants, the expected costs of politically sustainable technical solutions and the liabilities for residual risks – are reviewed and realigned at regular intervals. Complementing existing approaches with such a circular approach will strengthen funding arrangements and ensure their adequacy for decades to come.

    Keywords: Nuclear Energy
    Abstract: As the Fukushima Daiichi nuclear power plant (NPP) accident illustrates, many challenges have to be faced in maintaining safety over the long term in a damaged NPP following a severe accident. These comprise maintaining and monitoring a stabilised and controlled state of the damaged plant; implementing provisions against further failures; evaluating the plant damaged state from a physical and radiological standpoint and ranking related risks; preparing and achieving fuel retrieval (either fuel assemblies stored in spent fuel pools or fuel debris from damaged reactors); and managing safely plant recovery and accident waste. All these actions are to be conducted protecting plant personnel from radiation exposure. This status report reviews knowledge and experience gained through long-term management (LTM) of the Three Mile Island, Chernobyl and Fukushima Daiichi accidents, by identifying and ranking main issues and knowledge gaps. It also reviews the existing regulations and guidance, practices, technical bases and issues considered in member countries of the Nuclear Energy Agency regarding LTM of a severely damaged nuclear site. Finally, it proposes recommendations and areas for future investigation to enhance LTM of an NPP as regards necessary knowledge and provisions development, particularly for the optimisation of management of contaminated cooling waters.

    Abstract: The existing nuclear fleet remains the largest low-carbon source of electricity generation in OECD countries. In 2021 the average nuclear power plant had already been operating for 31 years and some 30% of reactors worldwide were already operating under long-term operation conditions. The long-term operation of this existing nuclear capacity will be essential over the next decade to keep decarbonisation targets within reach. At the same time, by keeping the long-term-operation option open, countries could also reap a wide-range of socio-economic benefits including more affordable and secure electricity supply. Nevertheless, an increasing number of reactors are being shut down earlier than expected due to policy decisions and increasing market pressures in some regions. In light of these trends, this study takes a holistic approach to identifying the key enablers for long-term operation of nuclear power plants. The attractiveness of long-term operation lies in its technical maturity, cost-competiveness and ease of implementation: it is a high-value option to support the energy transition while minimising potential risks along the way.

    Abstract: This report highlights the potential role of nuclear in contributing to the circular carbon economy as a low-carbon source of electricity, but also as a source of heat and system integration services. It further highlights the essential role played by the existing nuclear reactor fleet in supporting the resilience of the electricity system through the COVID-19 crisis, and the significant role that the nuclear sector can play in post-COVID-19 recovery efforts. As with all low-carbon technologies, a number of enabling policies are needed for nuclear power to play its full role in the circular carbon economy. They are outlined in the last section of this report. Building on these conclusions, G20 countries could take specific action in a number of areas, both individually and collectively.

    Abstract: A wealth of technical information exists on nuclear fuel cycle options – combinations of nuclear fuel types, reactor types, used or spent nuclear fuel (SNF) treatments, and disposal schemes – and most countries with active nuclear power programmes conduct some level of research and development on advanced nuclear fuel cycles. However, perhaps because of the number of options that exist, it is often difficult for policy makers to understand the nature and magnitude of the differences between the various options. This report explores the fuel cycle options and the differentiating characteristics of these options. It also describes the driving factors for decisions related to both the development of the fuel cycle and the characteristics resulting from implementing the option. It includes information on the current status and future plans for power reactors, reprocessing facilities, disposal facilities, and the status of research and development activities in several countries. It is designed for policy makers to understand the differences among the fuel cycle options in a way that is concise, understandable, and based on the existing technologies, while keeping technical discussions to a minimum.

    Abstract: This volume is the fourteenth of the series “Chemical Thermodynamics” published by the OECD Nuclear Energy Agency. It is the second update of the critical reviews published, successively, in 1992 as Chemical Thermodynamics of Uranium, in 1995 as Chemical Thermodynamics of Americium, in 1999 as Chemical Thermodynamics of Technetium, in 2001 as Chemical Thermodynamics of Neptunium and Plutonium and in 2003 as the first Update on the Chemical Thermodynamics of Uranium, Neptunium, Plutonium, Americium and Technetium. A team, composed of nine internationally recognised experts, has critically reviewed all the relevant scientific literature for the above mentioned systems that has appeared since the publication of the earlier volumes. The results of this assessment, carried out following the Guidelines of the Thermochemical Database Project, have been documented in the present volume, which contains new tables of selected values for formation and reaction data and an extensive bibliography. The database system developed at the NEA Data Bank ensures consistency within the recommended data sets. This volume will be of particular interest to scientists carrying out performance assessments of deep geological disposal sites for radioactive waste.

    Keywords: Nuclear Energy
    Abstract: The decisions made about exposure to ionising radiation tend to be driven by subjective judgements about the health risks that radiation exposure may cause. In order to reach decisions that are effective and sustainable, it is essential for nuclear safety regulators, governments, nuclear facility operators and other nuclear energy decision makers to communicate scientific, technical and regulatory information regarding radiological and other risks to all stakeholders. Communicating such information can be complex since people judge and evaluate risks differently depending on the context and on their perceptions of risk. In this context, the Nuclear Energy Agency (NEA) organised the “Stakeholder Involvement Workshop on Risk Communication: Towards a Shared Understanding of Radiological Risks” in September 2019. The workshop provided an opportunity for participants to share perspectives and lessons learnt in risk communication, identifying what has been effective and what has been less effective in the various cases. By understanding how situation-specific factors influence risk communication, a common framework addressing such circumstances can begin to emerge. This report attempts to capture the collective wisdom generated over the three days of interactions in the hope that the knowledge gained from this workshop will benefit governments and citizens alike.

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: Radioactive waste inventory data are an essential element in the development of a national radioactive waste management programme since these data affect the design and selection of the ultimate disposal methods. Inventory data are generally presented as an amount of radioactive waste under various waste classes, according to the waste classification scheme developed and adopted by the country or national programme in question. Various waste classification schemes have thus evolved in most countries, and these schemes classify radioactive waste according to its origin, to criteria related to the protection of workers or the physical, chemical and radiological properties of the waste and the planned disposal method(s). The diversity in classification schemes across countries has restricted the possibility of comparing waste inventories and led to difficulties in interpreting waste management practices, both nationally and internationally. To help improve this situation, the OECD Nuclear Energy Agency (NEA) developed a methodology that ensures consistency of national radioactive waste and spent fuel inventory data by presenting them in a common scheme in direct connection with accepted management strategy and disposal routes. This report provides the final version of the methodology and presenting scheme for spent nuclear fuel and the radioactive waste of all existing types. Additionally, there are recommendations in the report on how to enhance the comparability of national inventory data using the NEA methodology. The NEA support for joint efforts of the International Atomic Energy Agency and the European Commission on harmonisation of the reporting process by member countries to the Joint Convention and European Council Directive 2011/70 EURATOM is also presented in the report.

    Abstract: Small Modular Reactors (SMRs) are gaining recognition among policymakers and industry players as a promising nuclear technology. SMRs can be defined as nuclear reactors with a power output between 10 MWe and 300 MWe that incorporate by design higher modularisation, standardisation and factory-based construction levels enabling more predictable delivery models based on the economies of series. Today, more than 50 concepts are under development covering a wide range of technology approaches and maturity levels. The value proposition of the SMR technology also includes potential financing and system integration benefits. These attractive features, however, rely on a business case that requires the development of a global SMR market to become economically viable. Large-scale deployment of SMRs faces several technical, economic, regulatory and supply chain challenges and will need considerable governmental efforts and efficient international collaborative frameworks to be realised in the next decade.

    Abstract: Nuclear power plants are used extensively as base load sources of electricity. This is the most economical and technically simple mode of operation. In this mode, power changes are limited to frequency regulation for grid stability purposes and shutdowns for safety purposes. However for countries with high nuclear shares or desiring to significantly increase renewable energy sources, the question arises as to the ability of nuclear power plants to follow load on a regular basis, including daily variations of the power demand. This report considers the capability of nuclear power plants to follow load and the associated issues that arise when operating in a load following mode. The report was initiated as part of the NEA study “System effects of nuclear power”. It provided a detailed analysis of the technical and economic aspects of load-following with nuclear power plants, and summarises the impact of load-following on the operational mode, fuel performance and ageing of large equipment components of the plant.

    Abstract: In the 70-plus years of peaceful uses of nuclear energy, the nuclear industry has reached a mature awareness of its importance, influence and responsibility for and towards the world. Not only does it dutifully regulate itself in technical aspects, making the use of nuclear energy stricter and safer by any and all means possible, it also establishes policies, backed by legislation, for its decades-long activities. Thus, the industry has recognised the need to systematically approach and solve the issue of complete dismantling of its (previously operating) facilities and final disposal of the operational and decommissioning waste (including spent nuclear fuel (SNF)1). This sought end state must be reached both by technical means as well as by creating a sound system for today’s continuous accumulation of funds, needed for the future implementation of the selected technical solution (including final disposal of SNF).

    Abstract: Over the last decades, the world has become increasingly mindful of the potential impact of human activities on the environment and many governments have recognised the need to better assess the potential impacts of such activities prior to their authorisation. Legal requirements to perform environmental impact assessments (EIA) for activities likely to have environmental effects have been enacted under national, European and international law and have gained the status of international customary law.1 Due to the nature of the risks posed by the civilian use of nuclear energy on human health and the environment, it has become a requirement in most – if not all – countries that an EIA be performed prior to authorising the construction and operation of any nuclear installation, including nuclear power reactors.

    Abstract: It is essential that organisations in the nuclear community maintain a healthy safety culture to achieve common goals regarding the safe operation of nuclear facilities and the safe use of nuclear material. Regulatory bodies are no exception, as a key element of the interconnected system which includes licensees, research institutions, technical support organisations, as well as governmental organisations and other stakeholders. By their very nature, regulatory bodies deeply influence the safety culture and the safety of the organisations they regulate and oversee. Based on their regulatory strategy, the way they carry out their daily oversight work, the type of relationship they cultivate with licensees, the values they convey and the importance they give to safety, regulatory bodies profoundly impact the licensees’ safety culture, their sense of responsibility for safety and, by extension, the safety of their installations. Regulatory bodies apply a number of methods, practices and approaches to foster and sustain a healthy safety culture. This report provides an overview and practical examples to build the regulatory bodies’ safety culture competence and to perform self-reflection and self-assessment with regard to their own safety culture and its impact on the safety culture of the organisations they oversee. Drawing directly from the experiences from OECD Nuclear Energy Agency member countries, the report discusses effective methods to disseminate safety culture throughout the regulatory body, to build competence in safety culture, and to develop self-reflection and self-assessment activities. Finally, the report presents ten conclusions based on lessons learnt and best practices to inspire managers to continuously develop their regulatory body’s safety culture.

    Series Statement: Radiation Protection
    Keywords: Nuclear Energy
    Abstract: The Information System on Occupational Exposure (ISOE) is jointly sponsored by the Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). Since 1992, ISOE has provided a forum for radiological protection professionals from nuclear licensees and national regulatory authorities worldwide to share dose reduction information and operational experience aiming to improve the optimisation of radiological protection at nuclear power plants. As of 31 December 2018, the ISOE Programme included 76 participating licensees in 31 countries (352 operating units, 61 shutdown units and 10 units under construction and/or commissioning), as well as 28 regulatory authorities in 26 countries. The ISOE database contains occupational exposure information for 500 units, covering over 85% of the world’s operating commercial power reactors. In addition, the ISOE database contains dose data from 106 reactors that are shut down or in some stage of decommissioning. While ISOE is well known for its occupational exposure data and analyses, the Programme’s strength comes from its objective to share such information broadly among its participants. This 28th Annual Report presents the status of the ISOE Programme for the calendar year 2018. The report includes global occupational exposure data and analyses collected and accomplished in 2018, as well as information on the Programme achievements and principle events in participating countries.

    Abstract: Understanding the accident at the Fukushima Daiichi Nuclear Power Plant is important for safe and timely decommissioning of the reactors. This objective, together with the development of better computer codes for analysis of severe accidents, was the aim of the benchmark study conducted under the auspices of the OECD Nuclear Energy Agency. Through the diversity of the modelling codes and approaches, and the use of parametric studies, it has been possible to identify the more likely scenarios that can fit with the limited data available from the accident. The insights gained from the project will help guide research into severe accident behaviour, improve severe accident computer codes, develop accident mitigation and response at nuclear power plants, support regulatory oversight related to severe accidents, and inform policies on the development and deployment of nuclear technology.

    Keywords: Nuclear Energy
    Abstract: Experimental facilities in nuclear energy are key to addressing safety issues. The recent loss of some critical infrastructure, from facilities to industry expertise, has therefore become a concern for many countries. In response, the NEA has launched several efforts to address the matter as outlined in this report. Current safety issues, research needs and research facilities associated with currently operating water-cooled reactors in NEA countries are all addressed. Also included is an assessment of the present needs to maintain experimental databases. The Senior Group of Experts on Nuclear Safety Research, which produced this update of the 2007 report on the same issue, noted the success of previous reviews in helping maintain critical infrastructure and make a number of recommendations to preserve key research facilities and capabilities.

    Abstract: Energy markets will be significantly different in the future. The electricity generation system is becoming more diverse with the development of energy-related technologies including renewable energy sources, storage technologies and demand-side management. Beyond the electricity sector, various low-carbon energy technologies are being developed to respond to the need to decarbonise hard-to-abate sectors such as heavy industry and long-distance transportation. In this report the NEA investigates the changing needs of energy markets and the potential role of nuclear technologies as low-carbon energy sources. Focusing on the technical characteristics of advanced nuclear reactor systems, including Generation III/III+ reactors, small modular reactors and Generation IV reactors, it explores the ways these advanced nuclear technologies could address the future energy market needs. The conclusion is that advanced nuclear reactor systems, while complying with the flexibility requirements of the electricity grid and supporting system reliability, have a large potential as alternative low-carbon energy sources for residential and industrial heat supply and hydrogen production.

    Abstract: Climate change will create specific risks and challenges for nuclear power plants and the electricity system as a whole. Extreme weather events caused by climate change – such as floods, storms, heat waves and droughts – have already affected the operation of nuclear power plants. Any increase in the temperature of the water used to cool nuclear power plants can also lead to reductions in their power output due to decreasing thermal efficiency. This report sets out the adaptation strategies that can be effectively implemented to improve the resilience of existing plants as well as any new installations. The costs of adaptation to climate change can vary significantly depending on the type of reactor, the climate change issues affecting them, as well as the applicable regulations and standards. However, while these adaptation costs can, in some cases, be significant, the costs of inaction – both directly at the plant level and indirectly for the electricity system – are likely to be even higher.

    Abstract: The agency expects to receive a number of complex applications for advanced reactor designs in the near future. Congress recently passed legislation seeking to streamline our safety review for such applications, suggesting that the efficient and effective review of these applications is a national priority. However, commenters remain concerned that without similar efforts to seek efficiency in our NEPA process, these efforts will prove ineffective. They note that the length and cost of our existing NEPA process pose a steep and potentially insurmountable obstacle to advanced reactors.”

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: Radioactive waste results from many different activities in health care, industry, research, and power production. All such waste must be managed safely, with the protection of human health and the environment as the highest priority. After decades of research, the international scientific community is now confident that placing high-level radioactive waste in deep geological repositories (DGRs) is both safe and effective. The government of each country has the absolute right and responsibility to implement the energy and environmental policies it believes are best. In the case of the disposal of radioactive waste, it is paramount that these debates should be informed by objective facts. This report therefore aims to provide the general reader with the current state of knowledge with regards to the management of high-level radioactive waste in DGRs.

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: Radioactive waste repositories are designed to isolate waste from the living environment without human intervention over extended periods of time. Nevertheless, the intention is not to abandon the repositories, but to provide the oversight that is necessary to ensure that they are not forgotten by society. In response to this challenge, the Nuclear Energy Agency launched the international initiative “Preservation of Records, Knowledge and Memory (RK&M) Across Generations”. As a result, an in-depth understanding of this issue was developed, as well as a specific methodology to address it. The RK&M preservation toolbox, for example, offers a menu with 35 different preservation mechanisms and guidelines on how to combine and implement them. This report may be used as a general guide to the RK&M preservation topic. It presents a historical review, addresses ethical considerations, analyses the fundamentals of RK&M preservation, outlines various mechanisms and indicates how to develop these mechanisms into a systemic RK&M preservation strategy. The report aims to inspire and assist a variety of actors so that they can discuss and develop national and repository-specific RK&M preservation strategies.

    Abstract: Knowledge of basic nuclear physics data is essential for the modelling and safe operation of all types of nuclear facilities. The de fact international standard format, Evaluated Nuclear Data File 6 (ENDF-6) format, was designed originally for 1960s era punch-card readers. The replacement of the system of codes built off this format has been recognised as an important initiative. The ability to use increasingly high-fidelity nuclear physics, coupled to accurate uncertainties, is crucial for advanced simulations. This in turn requires more detailed and accurate data, then requiring improvements to the data storage standards, simultaneously enabling robust Quality Assurance and transfer of knowledge to the next generation. In 2013, the NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC) launched a project to review the requirements for an international replacement for ENDF-6. The recommendations prompted the creation of a new Expert Group on a Generalised Nuclear Data Structure (GNDS) in 2016 that has used these requirements as the framework for a new format specification. Following rigorous international review, version 1.9 was unanimously approved as the first official published format.

    Keywords: Nuclear Energy
    Abstract: Many countries are dealing with challenges stemming from nuclear and radiological legacy sites. In particular, managing these sites in an open and transparent fashion while taking into account the views of all relevant stakeholders and building confidence in the solutions adopted is an ongoing challenge. This report provides information on the challenges and lessons learnt in legacy management and regulation based on practical experience documented in 13 case studies and site visits conducted by the OECD Nuclear Energy Agency. A preliminary framework for a stepwise process to help reach an accepted and sustainable end-state is proposed based on this experience. The complex challenges and interactions among stakeholders in progressing in a harmonised, step-by-step manner are also examined in depth. The report concludes with recommendations for future international collaborative work to improve and test the preliminary framework, and to examine and address the complexity of the relevant interactions.

It is consequently important to put an end to this state of affairs: the long-promised complete nuclear disarmament appears to be the most appropriate means of achieving that result.”

    Abstract: Today, with the completion of First-of-a-Kind Gen-III nuclear reactors, the nuclear sector is at a critical juncture. These reactors have led in several parts of the world to delays and construction costs overruns that have challenged the competitiveness of nuclear power and are driving the risk perception of future projects. Against this background, a review of historical and recent lessons learnt from nuclear and non-nuclear project offers ample evidence that nuclear new build can be delivered cost and time-effectively. This study assesses the policy and governance frameworks needed to drive positive learning and continuous industrial performance for nuclear new build. The study also explores the risk allocation and mitigation priorities needed to define adequate financing schemes for these projects. In the longer-term, it identifies cost reduction opportunities associated with the harmonisation of code and standards and licensing regimes and new innovative designs (i.e. small modular reactors and advanced reactors).

    Abstract: The performance-based approach to the regulation of nuclear power generation for civilian use is an approach that requires a certain outcome but provides the regulated entity with the flexibility to determine how it can achieve this outcome.1 Such an approach is currently being employed, for example, in Canada, France and the United Kingdom. While some have argued that “significant work remains to be done before performance-based approaches can realize their full potential in the regulation of nuclear power plants”,2 a limited number of analyses have been dedicated to the approach.3 The author was thus inspired to share Canadian expertise in this area, as well as a description of the approach developed in Canada in recent decades.

    Abstract: In New York v. Nuclear Regulatory Commission (New York 2012),1 the US Court of Appeals for the District of Columbia (DC) Circuit vacated the 2010 update to what was commonly known as the US Nuclear Regulatory Commission’s (NRC or Agency) “Waste Confidence Decision”. The Waste Confidence Decision was premised upon the NRC’s professed confidence that spent nuclear fuel could and eventually would be disposed of in an underground repository and that spent fuel could be stored safely and without significant environmental consequence until that time. For decades, the decision had provided legal support for the Agency’s issuance and renewal of licences for power reactors to operate, even as the process for licensing and constructing a repository in the United States became delayed and ultimately stalled (as it remains today). The court ruled in New York 2012 that the NRC’s continued reliance upon its Waste Confidence Decision to support these licensing decisions was inconsistent with the US National Environmental Policy Act (NEPA), which requires US federal agencies to consider the full panoply of the environmental impacts of certain “major federal actions” (including decisions to licence nuclear facilities).2 The court required the Agency to further develop its analysis of the impacts of storing spent fuel for an extended period of time and to address the possibility of a repository not becoming available.

    Abstract: Advanced reactors have promise as the future of United States nuclear energy infrastructure. However, licensing these reactors presents many new questions for the nuclear community, particularly around developing a “technology-neutral” framework capable of handling a staggering amount of diversity in technologies and operating models. Congress’s enactment of the Nuclear Energy Innovation and Modernization Act (NEIMA) in early 2019 enables the United States Nuclear Regulatory Commission (NRC) to devote substantial resources to developing such a framework. Congress draws a distinction between the existing licensing framework that is focused on light water reactors (LWRs) and the technology-neutral framework that it directs the NRC to establish.

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: Radioactive waste repositories are designed to be intrinsically safe in that they are not dependent on the presence or intervention of humans. In response to this challenge, the Nuclear Energy Agency initiated the Preservation of Records, Knowledge and Memory (RK&M) Across Generations Initiative, calling on the international community to help create specific means to preserve RK&M. The concept of a key information file (KIF) emerged in response to the challenge presented by the large volumes of RK&M material generated by national disposal programmes. This concept has been developed into an important component of a RK&M preservation strategy. The KIF is designed to be a single, short document, produced in a standard format, with the aim of allowing society to understand the nature and intent of a repository, and thus to reduce the likelihood of unnecessary human intrusion. It should be made openly available and ultimately be widely distributed. This report describes the KIF concept in detail, in a manner that should enable those concerned with any particular repository to create their own versions. Three draft key information files, currently under development to support RK&M preservation in France, Sweden and the United States, are provided as examples.

    Series Statement: Radioactive Waste Management
    Keywords: Nuclear Energy
    Abstract: The nuclear sector has in recent years been placing increasing attention on the need to better understand variations between cost estimates for the decommissioning of nuclear power plants, as well as the relationship between estimated and actual costs, and the apparent escalation of these costs. Building on previous work by the Nuclear Energy Agency, Cost Benchmarking for Nuclear Power Plant Decommissioning examines approaches and methods for the benchmarking of nuclear power plant decommissioning costs. Particular focus is given to identifying key factors, drivers and constraints to implementing cost benchmarking. These factors are addressed from a broad range of perspectives in order to develop a roadmap for implementation that will garner sufficiently broad support from a wide base of interested stakeholders. The report also identifies a number of perceived barriers that may impede the implementation of benchmarking for decommissioning. Co-ordinated efforts and further analysis will be needed to help remove these barriers.

    Abstract: Current knowledge of the nuclear physics of fuels and materials provides an understanding and simulation of the operations of nuclear reactors and other systems, both under ordinary and exceptional circumstances. As part of a broad spectrum of collaborative activities underpinning research in basic nuclear sciences, the Nuclear Energy Agency (NEA) is supporting collaboration between experimentalists, theoreticians and modelling experts to advance the state of the art in nuclear data. This report offers an overview of collective results from 31 institutions in 15 NEA member countries, along with results from technical experts in the People's Republic of China, in the context of the NEA Collaborative International Evaluated Library Organisation (CIELO) Pilot Project. It reviews recent developments resulting from new measurements and semi-empirical models, as well as the validation of the CIELO nuclear data evaluations against suites of systems representing a wide range of current and future nuclear facilities. The CIELO project has delivered new, evaluated data for the isotopes of uranium, plutonium, iron, oxygen and hydrogen, which have been adopted in all nuclear data libraries released since the CIELO project was completed.

    Abstract: With almost 70% of the operating nuclear power reactors over 30 years of age, countries around the world are assessing whether to allow reactor operation past the 50 60 year mark and potentially up to 80 years. Ensuring a proper legal framework for the long term operation (LTO) of nuclear power reactors is a key component of such considerations. The aim of this report is to provide insights into the various laws, regulations and policies that contribute to different countries' approaches to LTO. By collecting information from more than 20 NEA member and non member countries, this report highlights both commonalities among approaches as well as possible reasons for variations. Ultimately, the information gathered can serve as a vital resource for future exchanges respecting the legal aspects of LTO, with a view to further development and strengthening of the collective understanding of these issues.

    Parallel Title: Erscheint auch als The supply of medical isotopes
    Keywords: Medizinprodukt ; Strahlentherapie ; Social Issues/Migration/Health ; Science and Technology ; Industry and Services ; Nuklearmedizin
    Abstract: This report explores the main reasons behind the unreliable supply of Technetium-99m (Tc-99m) in health-care systems and policy options to address the issue. Tc-99m is used in 85% of nuclear medicine diagnostic scans performed worldwide – around 30 million patient examinations every year. These scans allow diagnoses of diseases in many parts of the human body, including the skeleton, heart and circulatory system, and the brain. Medical isotopes are subject to radioactive decay and have to be delivered just-in-time through a complex supply chain. However, ageing production facilities and a lack of investment have made the supply of Tc-99m unreliable. This report analyses the use and substitutability of Tc-99m in health care, health-care provider payment mechanisms for scans, and the structure of the supply chain. It concludes that the main reasons for unreliable supply are that production is not economically viable and that the structure of the supply chain prevents producers from charging prices that reflect the full costs of production and supply.

    Keywords: Nuclear Energy
    Abstract: CSNI Technical Opinion Paper No. 17: Fire Probabilistic Safety Assessments for Nuclear Power Plants: 2019 Update provides an authoritative review of the current status and use of the fire PSA in nuclear power plants. The report demonstrates that while fires at a particular plant site are highly dependent on plant and site specific factors, they are nonetheless an important contributor to overall risk. Insights from fire PSAs are generally found to be aligned with operating experience and to be representative of the expected plant response, making them valuable in addressing risk. This report should be useful for regulators overseeing the use of fire PSAs in nuclear installations, practitioners in understanding the considerations for performing or reviewing fire PSAs, and researchers in identifying areas requiring further study.

    Abstract: In the nuclear field, security and safety are not completely distinct concepts. Both share the “common … aim of protecting persons, property, society and the environment”,1 but do so in different ways. As explained by the IAEA, nuclear security addresses “the prevention and detection of, and response to, theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear material, other radioactive substances or their associated facilities”.

    Abstract: A mature and well-guided multi-stage approach to the validation of nuclear power plant control room designs has the potential to reduce the risks involved in the design process. Such an approach can also increase the effectiveness of, and efficiencies in, the validation process, as well as overall confidence in the results. This relatively new concept of multi-stage validation has yet to be defined in the technical literature, and thus the report describes the approach and the rationale for validating systems through a series of successive, co-ordinated validation activities. The scope of application of multi-scale validation addressed in the context of this report includes aspects related to both the human factors engineering of new nuclear power plant main control room designs and modifications to existing control room designs. The objective is to provide a common reference for future dialogue, research and development concerning the multi-stage validation approach, and ultimately to support the safe operation of nuclear power plants worldwide.
