Utility Perspective on SMRs Presented by Jack A. Bailey VP Nuclear Generation Development NRC Commission Briefing March 29, 2011

TVA’s Renewed Vision Reflects Interests of Many Utilities Provide Cleaner Low-Cost Power Cleaner Air High Reliability Greater Energy Low Rates Efficiency Responsible More Nuclear Stewardship Generation Coal Nuclear Hydro Gas/Oil FY2020 Generation FY2010 Generation 2 Renewables/EE

Small Modular Reactors Potential Benefits  Simplified “passive safety” LWR  Underground containment and used fuel storage  Four years or more between refuelings  Shop fabricated, rail shipped  Incremental generation when and where its needed  Lower transmission system impacts 3

SMR Challenges  Overcoming economy of scale challenges. – Regulations and industry practices designed for larger plants.  Realizing goal of adding incremental modules efficiently when needed. – License multiple modules before needed, so that can build when needed.  Providing adequate and effective manufacturing oversight and inspection 4

Lessons Learned From Advanced Reactor Programs Apply  Standardization – Achieve and maintain  Design Centered Working Groups – One issue one review – Design specific through industry team – Generic issues through NEI  Industry Teams – Stay committed through both licensing and construction 5

First Mover Consideration of 10CFR50 versus 10CFR52  10CFR50 is suitable for first-of-a-kind designs  Increased potential risk of 10CFR50 can be managed by: – Completing substantial engineering prior to construction – Clear identification and early NRC review of critical design features  10CFR50 and 10CFR52 both need to ensure standardization of new designs  10CFR52 clear preference for long-term standardized deployment 6

Main Discussion Points  Many articulated reasons for considering SMRs along with larger ALWRs.  While similar in design to large reactors, large margins to safety expected to be met with simpler and fewer plant systems.  Industry working with NRC to right size certain regulatory requirements commensurate with the risk of SMRs, using lessons learned from advanced new plant activities.  Successful navigation among the possible regulatory paths just as critical to successful deployment of SMRs as managing total construction costs. 8
