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
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!
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
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
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.

Proprietary Information 15
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

Prevention Design Features
27
High Pressure ContainmentEnhanced Safety
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.
28
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.
29
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. 30

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
32
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
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
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
