Nuclear Renaissance: Current Assessment
• Growing consensus that global warming is sufficiently credible that a prudent response is justifiable– Energy and transportation sectors should assume an
increasingly carbon-constrained future– Nuclear seen as most expandable non-emitting source– Nuclear and renewable energy are sustainable
• Baseload demand increases; future regional shortfalls• Excellent performance and asset value of current plants• Success of License Renewal bodes well for new plants• Low production costs (good situation likely to get better)• Financial incentives for first few new plants• Growing public acceptance and support for nuclear energy• Leadership from Administration and Congress

EPRI-INL Future Nuclear R&D Strategy Paper
• “The Nuclear Energy Development Agenda: A Consensus Strategy for U.S. Government and Industry” January 2006
Background:
• Significant divergence between industry and DOE regarding nuclear R&D agenda over last decade
• Long-term DOE vs. short-term industry agendas
• Lack of convergence on:
– Program priorities, timing, rationale and communications
– Marketplace needs and commercialization strategy
– Resource and cost-sharing
17© 2006 Electric Power Research Institute, Inc. All rights reserved.
EPRI-INL Future Nuclear R&D Strategy Paper
Solution:
• Create a consensus agenda for industry & DOE
– S. Specker & J. Grossenbacher agreement, May 2005
– 80-20 paradigm to bridge gaps and foster collaboration
– Joint EPRI-INL effort to draft an R&D plan, Fall 2005
– Aggressive planning assumptions; realistic outlook, science-based and market-driven outcomes
• Guiding principle:
– All programs and systems are in an ‘R&D Continuum’, i.e., they are all interrelated

Consensus Strategy Goals of EPRI-INL Paper
1. Ensure continued effectiveness of operating fleet of NPPs.
2. Establish an integrated spent fuel management system consisting of centralized interim storage, the YM repository, and, when necessary, a closed nuclear fuel cycle.
3. Build a new fleet of nuclear plants for electricity generation.
4. Produce hydrogen at large-scale for transportation and industry, and eventually for a hydrogen economy.
5. Apply nuclear systems to desalination and other process heat applications.
6. Greatly expand nuclear fuel resources for long-term sustainability, commercializing advanced fuel cycles when market conditions demand them in the long term.
7. Strengthen proliferation resistance and physical protection of closed nuclear fuel cycles both in U.S. and internationally.

Planning Assumptions in EPRI-INL Paper
• Currently operating plants granted life extensions to 60 yrs, some to 80 yrs; higher burnup fuel & digital controls are adopted
• Electricity: 30 GWe new nuclear generation by 2020, 100 GWe by 2030, 400 GWe by 2050
• Process heat: prototype VHTR by 2020, 12 operating by 2030, 200 by 2050 focused on H2 for oil, gas and chemical industry
• Desalination begins to be addressed in 2020• Yucca licensed in 2015; two interim storage sites open• Bipartisan support for integrated spent fuel management plan by
2015 (extends Yucca capacity and long-term monitoring; creates centralized interim storage (or “aging pads”); commits to reprocessing demonstration plant by 2030)
• New fast reactor demonstration plant by 2035• Deployment of recycle phased with nuclear’s expansion; timed
to coincide with higher uranium prices (market-driven transition)

Conclusions of the EPRI-INL Paper
• Nuclear energy development in the U.S. requires a consensus of industry and government
• Significant LWR research is needed (e.g., HBU fuel)• Nuclear’s contribution to process heat is an important priority• A proliferation-resistant closed nuclear fuel cycle should be
ready for deployment by mid-century– Primary driver: energy/environmental sustainability– ‘Full actinide recycle’ important to integrated, cost-
effective spent fuel management – Existing reprocessing technology not adequate to
accomplish global non-proliferation and domestic spent fuel management objectives
• Strategy for rebuilding U.S. nuclear infrastructure is needed

Implications for Industry’s Strategy
• EPRI-INL Strategy supports adoption of a balanced view:
– Near-term initiatives form the foundation for longer term nuclear energy development and expansion
• Continued safe and effective operation of our current fleet of reactors
• Near-term licensing and deployment of ALWRs
• Licensing & construction of Yucca Mountain
– Medium-term application of nuclear energy into commercially viable process heat applications, including hydrogen for industrial and transportation missions, and desalination
– Long-term goals become possible with priority on recycling R&D now
• Expanding nuclear fuel resources for long-term sustainability (breeding)
• Developing an integrated spent fuel management strategy (burning)
• Supporting global deployment of nuclear energy (fuel lease/take-back and nonproliferation initiatives)

Implications for DOE’s Fuel Cycle Strategy
• EPRI-INL Paper: U.S. can embark on major new plant deployment and not have to build a second repository, even if closed fuel cycle deployment not achieved until 2050.
• EPRI-INL conclusion contingent on establishing an integrated, cost-effective spent fuel management strategy:– Allowing for expansion of the YM site to its full technical capacity
– Reducing the rate of spent fuel generation via development of high performance LWR fuel (factor of two achievable)
– Maintaining engineered cooling of YM for 50+ years prior to closure
– Providing for interim centralized storage or “aging pads”
– Deploying multi-purpose canisters approved by NRC
– Implementing an effective spent fuel transportation system
– Eventual recycling of spent fuel to reduce volume and heat rate, thus making much more effective use of repository space.

Nuclear Renaissance: Near-Term Challenges
• High capital cost (mitigated by standardization, incentives)
• New Plant Licensing:
– Uncertainty in regulatory process
– Process duration; implications to time-to-market
– Up-front licensing resource demands
• Confidence in spent fuel management solutions
• Infrastructure, especially in rapid expansion scenarios:
– Fabrication and manufacturing capacity
– Engineering capability
– Skilled construction trades
– QA, NDE, HP, O&M personnel
