19 The Perspective Today Small Modular Reactors represent the innovation that is the competitive edge for this country. Nicole Y. Lamb Hale Assistant Secretary for Manufacturing & Services U.S. Department of Commerce Platts Nuclear Conference 16 February

20 NuScale Changed the Game NuScale was the first to offer the market a commercially viable modular, scalable light water design Modular factory manufacturing of major components and systems lowers costs, improves quality, shortens construction Scalable incremental addition of nuclear generating capacity produces cash flow sooner, places plant in rate base earlier Commercially viable light water technology provides clear path to licensing Time Magazine SMRs a Top 20 Green Tech Idea, December 2010 Greentech Media named Modular Nuclear Power as Number 1 on its list of Top Ten High Concepts for

21 NuScale Power History Oregon State University builds ¼ scale test facility to support Certification of the AP600 and AP1000 without requiring a prototype (1990s) NuScale design (MASLWR) and test facility originally developed under DOE funded program with cosponsors in OSU refined and developed the design with proprietary improvements ( ) NuScale Power Inc. formed in June Techtransfer agreement with OSU provides exclusive use of the Integral System Test facility and patents. t Establish Executive Team and staff of world-class engineers Gain commitment from US NRC to support licensing Secure support from US Congress and US DOE 5

22 NuScale: Prefabricated, Simple, Safe NSSS is Factory Built Entire NSSS prefabricated and shipped by rail, truck or barge Natural Circulation Cooling Inherently safe Eliminates major accident scenarios Improves economics - Eliminates pumps, pipes, valves Large natural heat sink Simplifies and enhances safety case Proven Technology Below Ground Enhances security and safety PRVs STEAM H H H Turbine Bypass M H FEEDWATER H Reactor Recirc Valves FW PUMPS TURBINE CONDENSER COOLERS Condensate Polishers OFF-THE- SHELF 6

27 Changing the Face of Energy

28 NuScale: Changing the Face of Energy Economies of Small Eliminate complex, expensive systems less to build, operate, maintain Factorymanufacturing and shorter construction time means greatercapital certainty Inherent Safety Natural circulation for passive always on on cooling Not subject to large LWR scenarios large break LOCA, SBO Siting Flexibility Smaller footprint. Seismically robust. Reduced water requirements. Multiple methods for cooling. True Scalability Up to 12 modules producing 540 Mwe Multiple applications: commercial power, desalination, district heating. 12

29 Everything Changed Except Business Risk Old Nuclear Every yplant is different Separate licenses for Construction and Operation New Nuclear NRC Design Certification standardizes plant designs for 20 years Combined Construction & Operating License issued before construction begins Capacity factors ~ 70% Capacity factors routinely exceed 90% Active safety systems require emergency power to operate All plants > 1000 MWe requiring large financial commitment Passive safety systems rely on natural circulation All plants > 1000 MWe requiring large financial commitment 13

30 NuScale: The Economies of Small DESIGN SIMPLICITY & SCALABILITY FACTORY FABRICATION MODULAR CONSTRUCTION INNOVATIVE OPERATIONS Reductions in: ECONOMIC IMPACTS Component Costs Construction Time Overnight Capital Costs Total Project and $/kw Finance a cecosts Operations & Maintenance Competitive Lifecycle Costs 14

31 Simplicity = Greater Safety, Lower Costs and Risks Proven technology Fewer systems and components than traditional plants Less to Develop Less to Design Less to License Less to Build Less to Operate Less to Maintain 15

32 SAFETY & LICENSABILITY

33 Inherently Safe Reactor Modules Natural Convection for Cooling Inherently safe natural circulation of water over the fuel driven by ygravity No pumps, no need for emergency generators Seismically Robust System is submerged in a pool of water below ground in an earthquake resistant building Reactor pool attenuates ground motion and dissipates energy Simple and Small Reactor is 1/20 th the size of large reactors Integrated reactor design, no large-break loss-of-coolant accidents Defense-in-Depth Multiple additional barriers to protect against the release of radiation to the environment 45 MWe Reactor Module High-strength stainless steel containment 10 times stronger than typical PWR Water volume to thermal power ratio is 4 times larger resulting in better cooling Reactor core has only 5% of the fuel of a large reactor 17

34 Large Pool of Water Holds Reactor Modules NuScale nuclear power reactors are housed inside high strength steel containment vessels and submerged in 4 million gallons of water below ground level inside the Reactor Building. 12 module, 540 MWe NuScale Plant The Reactor Building is designed to withstand earthquakes, floods, tornados, hurricane force winds, and aircraft impacts. Reactor and containment are submerged in underground steel-lined concrete pool with 30-day supply of cooling water. Any hydrogen released is trapped in containment vessel with little to no oxygen available to create a combustible mixture. 18

35 Added Barriers Between Fuel and Environment Conventional Designs 1. Fuel Pellet and Cladding 7 2. Reactor Vessel 3. Containment 6 NuScale s Additional Barriers 4. Water in Reactor Pool (4 million gallons) 5. Stainless Steel Lined Concrete Reactor Pool 6. Biological Shield Covers Each Reactor 5 4 Ground level Reactor Building 19

36 Stable Long Term Cooling Reactor and nuclear fuel cooled indefinitely without pumps or power WATER COOLING BOILING AIR COOLING 20

37 Spent Fuel Pool Safety Increased Cooling Capacity More water volume for cooling per fuel assembly than current designs Low Density Spent Fuel Racks permit air cooling in the event of loss of coolant Redundant, cross-connected reactor and refueling pool heat exchangers provide full back-up cooling to spent fuel pool. Stainless steel refueling pool liners are independent from concrete structure to retain integrity External Coolant Supply Connections Auxiliary external water supply connections are easily accessible to plant personnel and away from potential high radiation zones (current problem in Japan) Below Ground, Robust Deep-Earth Structure. Below ground spent fuel pool is housed in a seismically robust reactor building Pool wall located underground is shielded from tsunami wave impact and damage Construction of structure below ground in engineered soil limits the potential for any leakage 21

50 TVA Chooses 10 CFR Part 50 for First-of-a-Kind (FOAK) Project Licensing i Current positive experience and project expertise with Part 50 licensing i process Less cost and potentially less time to get to point where you can construct CP issuance Modifications during construction easier to accommodate useful for first-of-a-kind Testing and verification of design established later versus defining completely upfront Regulator has opportunity to evaluate as-built plant prior to operating license issuance. 10CFR52 still appropriate and preferred for standardized deployment after FOAK 12

51 Construction Permit Project Activities Establishing Construction Permit project infrastructure Schedule Procedures/Processes Organization Integration with Generation mpower Licensing NRC Interactions underway Focus on key regulatory issues Regulatory Framework under development Current activities focus on confirming licensing certainty 13

52 Site Characterization Activities Previous site evaluation data Ecological surveys Cultural surveys Meteorological data collection Subsurface investigation Site layout plan Surface water level calculations Site infrastructure Construction Permit Site Characterization Critical to Confirming Siting Flexibility 14

53 Conclusion Nuclear can safely remain an essential part of a national energy policy in order to achieve clean air goals SMRs build upon the general benefits of nuclear and offer additional potential benefits Total cost per unit, price certainty, and shorter cash flow durations will benefit financing of new SMRs Licensing certainty is critical for SMR deployment Finding creative ways to partner and learn from a Regional or National SMR market model will allow for maximum benefits 15
