10 Fukushima Daiichi: Key NEA Conclusions After the Accident NEA member countries determined that their reactors were safe to continue operation. New safety enhancements related to extreme events and severe accidents should be implemented. The Fukushima Daiichi NPP accident revealed significant human, organisational and cultural challenges Organisation for Economic Co-operation and Development 10

11 The Big Lessons Vital to Understand the Natural Hazard Risks Facing Each Plant Extreme Events can Occur at Any Time and Cannot be Predicted Recovering from Disaster is At Least as Important as Preparing for Disaster Human Aspects of Nuclear Safety May be as Important as Technical Aspects 2016 Organisation for Economic Co-operation and Development 11 11

12 Safety Has Been Enhanced Since 3/11 Performed external hazard reassessments Reinforced flood protection measures Added mobile systems to cool cores and spent fuel pools Increased robustness of electrical power supplies Improved training and procedures for severe accident management Filtered vent and filtering strategies Greater consideration of safety culture characteristics and organisational factors in decision making processes 2016 Organisation for Economic Co-operation and Development 12

23 In May 2014, ministers and representatives of OECD member countries and the European Union gathered at the Ministerial Council Meeting invited the OECD to work with the International Energy Agency (IEA), the Nuclear Energy Agency (NEA) and the International Transport Forum (ITF) to continue to support the UNFCCC negotiations and to examine how to better align policies across different areas for a successful economic transition of all countries to sustainable lowcarbon and climate-resilient economies and report to the 2015 OECD Ministerial Council Meeting (3-5 June).

24 Challenge Two: Market Design and Failures Current designs of wholesale electricity markets in many OECD countries are not strategically aligned with the low-carbon transition APT Report June 2015 Electricity market design operating in most OECD countries brings challenges for low-carbon investment: Entry of renewables depresses average electricity prices Electricity price risk due to scarcity pricing affects real value of revenues and profits CO 2 prices are not providing sufficient incentives for low carbon investments Out of market financing of variable renewables such as wind and solar creates overcapacity but contributes little to security of supply due to variability and absence of dispatchability 2016 Organisation for Economic Co-operation and Development

Distortions and failures in electricity markets that impact financial competitiveness of baseload plants Persistent questions about long-term operation of current plants and constructability of Gen III/Gen III+ plants Unanswered questions about technology, cost, and regulatory issues regarding SMRs, Gen IV reactors, and other advanced technologies In some countries, public acceptance concerns about safety in the aftermath of the Fukushima accident Continuing international concerns about non-proliferation associated with expanded use of civilian nuclear power Ongoing challenges in many countries regarding long-term high level waste storage and disposal 2016 Organisation for Economic Co-operation and Development 25

29 Nuclear Waste and Nonproliferation: A Review of the Facts When civilian nuclear power was developed in the 1950s, recycling of spent nuclear fuel (SNF) was an integral aspect of the vison. While not ideal, plutonium from civilian SNF can be extracted for weapons purposes. But the global expansion of civilian nuclear power does not increase proliferation risks. Disposal of SNF in geologic repositories is practical and technically implementable. But direct disposal of SNF does not eliminate all potential proliferation concerns. Closure of the fuel cycle would assure that fissile material is never misused and is never allowed to enter the environment Organisation for Economic Co-operation and Development 29

30 Current Reprocessing Technology: Benefits and Barriers Potential Benefits Reduces HLW Volume Reduces actinide content of HLW Waste is easily stored and managed (vitrified logs) Enables use of 25 to 30% more energy than oncethrough fuel cycle Enhances energy security Barriers and Issues Concerns about separated plutonium Could encourage global expansion of reprocessing Concerns about environmental impacts Does not significantly reduce repository requirements Cost 2016 Organisation for Economic Co-operation and Development 30

31 Advanced Recycling Technology: Technology Can Provide Options In contrast to current reprocessing technology, advanced P&T can: dramatically alter long-term HLW disposition by reducing radiotoxicity and heat load in addition to volume reduce the monitoring period of final repositories to timescales within human experience simplify long-term safety issues associated with final disposition (elimination of most actinides and potentially some long-lived fission products) create pathways for secure and easily monitored use of nuclear materials Multi-recycle of transuranics can lead to very high utilization of energy content of uranium fuel 2016 Organisation for Economic Co-operation and Development 31

34 The Vision Thing: Our Biggest Technology Challenge Early 1950s: AEC and NASA started with little; limited infrastructure, limited proven industrial support. Over about 15 years both experienced tremendous growth and both made incredible technological progress. 1970s both initiated bold steps into the future that proved difficult and costly 1980s-1990s public support and interest waned and resources reduced. AEC Chair Glenn Seaborg and NASA Administrator James Webb July 1961 Today little significant progress being made and direction is unclear. Bold initiatives have been largely left to private ventures Organisation for Economic Co-operation and Development 34

35 Nuclear Innovation 2050: Pursuing Global Agreement on the Nuclear R&D Needs for the Future What technologies will be needed in 10 years? 30 years? 50 years? What R&D is needed to make these technologies available? Is the global community doing the R&D needed to prepare for the future? Can we cooperate to do more? 2016 Organisation for Economic Co-operation and Development 35

36 NEA Education Skills & Technology (NEST) Framework NEA Countries have identified a need to energise students and young professionals to pursue careers in nuclear science and technologies by: Establishing a multinational framework between interested countries to maintain & build skills capabilities Establishing international links between universities, academia, research institutes and industry Attracting technologists from other disciplines to address nuclear technology issues Involvement in solving real-world problems 2016 Organisation for Economic Co-operation and Development 36 36

37 NEST: Bringing Students and Young Professionals in Nuclear R&D Students will participate in multinational projects jointly with experienced engineers and researchers, and university professors Students will work with their counterparts around the world as part of international teams to pursue advanced research projects Projects will create practical knowledge in nuclear science, advanced and innovative nuclear technologies, materials, and computer codes NEST is designed to bring a multidisciplinary approach and creativity to foster innovations for a low carbon sustainable future 2016 Organisation for Economic Co-operation and Development 37 37
