Bombay 27.4 Jakarta 21.2 Beijing 19.4 Lagos 24.4 Sao Paulo 20.8 Dacca 19.0 Shanghai 23.4 Karachi 20.6 Mexico 18.8

  6. Our Nation’s Energy Challenges “We simply cannot meet today’s energy needs – much less tomorrow’s – with yesterday’s energy infrastructure and technologies,” - Energy Subcommittee Chairman Judy Biggert, 2005

  7. Our Nation’s Energy Challenges(1) Growing Demand for Electricity • DOE projects that U.S. electric power demand will increase dramatically: • From 3,883 Billion kW-hr (2003) to 5,220 Billion kW-hr (2025) (~18 x 1015 Btu) • Would require an additional 153 new 1000 MW(e) plants by the year 2025!

  8. Our Nation’s Energy Challenges(2) Dependence on Foreign Oil • U.S. imports more than 50% of the oil it consumes. • About 20 Million Barrels/day • Accounts for more than half the trade deficit. “Keeping America competitive requires affordable energy. Here we have a serious problem: America is addicted to oil, which is often imported from unstable parts of the world.” – President Bush

  9. Our Nation’s Energy Challenges(3) Environmental Concerns • Greenhouse Gas Emissions • Global Warming • Acid Rain • Fossil Fuel Plants emitted over 1,700 Million tons of Carbon Dioxide into the Atmosphere in 2005 • Fish and Wildlife concerns are closing Hydro-Electric plants

  10. Our Nation’s Energy Challenges(4) Cost of Energy Production1995-2007, In 2007 cents per kilowatt-hour • Costs for Oil and Natural Gas continue to rise. http://www.nei.org/documents/Vision2020_Booklet.pdf

  11. Our Nation’s Energy Challenges(5) Finding a Sustainable Energy Mix • Square miles of land required to produce 1,000 MW(e) • Renewable energy sources are diffuse.

  12. Why Nuclear Power? • 1,780 pounds of coal • 149 gallons of oil One Uranium Fuel Pellet • 17,000 cubic feet of natural gas

  13. Pressurized Water Reactor • Currently 104 operating nuclear power reactors in the U.S. • 20% of total electrical generation

  14. Recycling Used Nuclear Fuel *500 YEAR SUPPLY BREEDER REACTOR NUCLEAR WEAPONS CONVERSION TO FUEL *Assuming 2x current annual electricity usage

  15. Proprietary Information

  16. Proprietary Information Business Overview • NuScale is commercializing a 45 MWe system that can be “numbered up” to meet customer requirements of virtually any size. • NuScale technology developed and tested by Oregon State University. Company formed in 2007 with tech-transfer agreement from OSU. • Design innovations simplify construction, strengthen safety, reduce costs and financial risks, and improve reliability • Reliance on existing light water technology reduces regulatory risk and increases speed to market

  17. Key Personnel Dr. Paul Lorenzini Chief Executive Officer Experienced senior executive. President, Pacific Power & Light CEO, PowerCorp Australia VP/General Manager, Rockwell Hanford Operations Dr. Jose Reyes Chief Technical Officer Internationally recognized for leadership in developing scalable test facilities for nuclear plants. Designed, built and operated facilities used for NRC certification of Westinghouse AP600 and AP1000

  18. Strategic Partner - Kiewit Construction: NuScale / Kiewit MOU signed April 2008 • Employee-owned company; $6 billion annual revenue with 120 year history and 16,600 Employees • FORTUNE’s most admired company in the engineering and construction industry in 2007 • Major power plant constructor • Major commitment to new nuclear projects based on past nuclear construction experience • Full “one-stop shop” capability • 250-acre manufacturing facility in Corpus Christi, Texas Kiewit Corporate Headquarters Omaha, NE 18

  19. The Team: Best In Class” Industry Partners and Contractors • In addition to Kiewit, NuScale is working with industry partners, contractors, and suppliers to build a first class product delivery team.

  20. PROPRIETARY INFORMATION NuScale Power Project Organization • Owner • Site selection • Licensing (ESP/COL) • Operations • Nuclear Vendor (NuScale) • Design & Engineering (NSSS) • Licensing (Certification) • Support services A/E Constructor (Kiewit) Design & Engineering (BOP) Project Management Site Preparation & Construction Suppliers Fabricate Modules Steam Generator Forgings CRDM’s

  21. The Product: Prefabricated, Simple, Safe… • Construction Simplicity: • Entire NSSS is 60’ x 15’. Prefabricated and shipped by rail, truck or barge • Natural Circulation cooling: • Enhances safety – eliminates large break LOCA; strengthens passive safety • Improves economics -- eliminates pumps, pipes, auxiliary equipment • Below grade configuration enhances security • Flexibility: • Capacity additions match demand growth • On-line refueling improves reliability Only 1 of 2 FW trains shown

  22. … While relying on proven LWR technology • Light water technology utilizes large existing base of R&D • NuScale can be licensed within existing regulatory framework • Fully integrated prototype test facility available for licensing • “Off-the-shelf” systems (turbine-generators; fuel) facilitate commercialization

  23. Each module is an independent power module

  24. Multiple-Module Complex – Flexible Capacity (12 modules – 540 MWe)‏

  25. Multi-Module Control Room

  26. NuScale Nuclear Power Plant - Quick Facts

  27. Engineered Safety Features • High Pressure Containment Vessel • Shutdown Accumulator System (SAS)‏ • Passive Safety Systems • Decay Heat Removal System (DHRS)‏ • Containment Heat Removal System (CHRS) • Severe Accident Mitigation and Prevention Design Features

  28. Capable of 3.1 MPa (450 psia)‏ Equilibrium pressure between reactor and containment following any LOCA is always below containment design pressure. Insulating Vacuum Significantly reduces convection heat transfer during normal operation. No insulation on reactor vessel. ELIMINATES SUMP SCREEN BLOCKAGE ISSUE (GSI-191). Improves steam condensation rates during a LOCA by eliminating air. Prevents combustible hydrogen mixture in the unlikely event of a severe accident (i.e., no oxygen). Eliminates corrosion and humidity problems inside containment. High Pressure Containment Enhanced Safety

  29. Decay Heat Removal System (DHRS)‏ • Two independent trains of emergency feedwater to the steam generator tube bundles. • Water is drawn from the containment cooling pool through a sump screen. • Steam is vented through spargers and condensed in the pool. • Feedwater Accumulators provide initial feed flow while DHRS transitions to natural circulation flow. • Pool provides a 3 day cooling supply for decay heat removal.

  30. Containment Heat Removal System (CHRS) • Provides a means of removing core decay heat and limits containment pressure by: • Steam Condensation • Convective Heat Transfer • Heat Conduction • Sump Recirculation • Reactor Vessel steam is vented through the reactor vent valves (flow limiter). • Steam condenses on containment. • Condensate collects in lower containment region (sump). • Sump valves open to provide recirculation path through the core.

  31. Additional Fission Product Barriers Fuel Pellet and Cladding Reactor Vessel Containment Containment Cooling Pool Water Containment Pool Structure Biological Shield Reactor Building NOT TO SCALE

  32. Expert panel review confirms safety June 2-3, 2008, a panel of experts convened to develop a Thermal-Hydraulics/Neutronics Phenomena Identification and Ranking Table (PIRT) for the NuScale module. Large-break LOCA eliminated by design Since all water “lost” out of the primary system can be recovered by opening the sump recirculation valves, it is impossible to uncover the core during design bases LOCAs Therefore even a small-break LOCA does not challenge the safety of the reactor

  33. Enhanced Public Safety • Greater seismic resistance • Fewer accident scenarios - no LOCA, inability to uncover core • Simplified operations and safety systems • Multiple barriers and greater security • Smaller Emergency Planning Zone

  34. Reduced licensing and technology risks • Relies on existing LWR technology and licensing base • Prototype integral test facility existing and available • Plant simplicity and safety advantages reduce licensing challenges

  35. Security and Safeguards Advantages • Safety maintained without external power • Below-grade • Power Module (NSSS and Containment) • Control Room • Spent Fuel Pool • Low profile building • Containment pool Impact Shield for aircraft

  36. Capturing the Economies of “small” • Smaller unit size reduces financial exposure • Can be built faster in a series of smaller units • Interest during construction reduced • Better regulatory treatment • Moves NSSS construction off-site • Upfront capital requirements reduced • Capacity added to meet demand growth • Less generation per shaft – avoids large “single shaft risk.” • “Pinch Points” avoided Forgings for conventional nuclear plants done by Japan Steel Works.

  37. NuScale Status Progress and Momentum in 2008 • Engaged industry’s best • Raised company profile • Kiewit finalizing costs estimates and construction plan • Second NRC pre-application held in November 2008 • On track to file Design Certification application 2010 • Discussing MOUs for feasibility studies with prospective domestic and international customers
