Solution: B&W’s mPowerTM Reactor Modular Approach
• Flexible and scalable to customer requirements Integrated reactor modules Multi-unit (1-10+) plant 100 percent shop manufactured Rail-shippable
• Reduced licensing risk, construction cost, & schedule Evolved PWR-type concepts Passive safety No on-site NSSS construction Three years to start-up
• Integrated and simplified NSSS with fewer components Internal helical coil SG No need for safety-grade backup power No external pressurizer Conventional core and standard fuel
• Simplified operations and maintenance Four plus-year core design Sequential partial-plant outages Standardized BOP
Lower risk and cost solution…

Public-Private Partnerships•To be Successful Program Must:Select appropriate sites for reactor deployments•Critical missions•Strategic offensive and defensive capabilities•High energy costs and usage
−Production tax credits and loan guarantees could make nuclear power more competitive at more sites
Develop a long-term land lease agreement (EUL?)•Win-Win arrangement for Air Force and
commercial developerDevelop a long-term power purchase agreement •Mechanism for third-party financing•Minimizes market risks for initial units
