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

Adaptability to Government
Installations
•Small compact standardized design
•Passively safe
•Scalable
•Long refueling cycle
5+ years at <5% enriched U235
~10 years at <10% enriched U235
•Built in the USA
Heavy forgings from Lehigh Heavy Forge
Component fabrication at B&W’s Mt. Vernon, Indiana
facility
Fuel fabrication at B&W’s Lynchburg, VA facility
Modular construction techniques
Transportable size
Adaptability to Government
Installations
•Potential for Co-Generation
Steam
Desalination
Electrolysis for hydrogen and oxygen production
• Fischer-Tropsch?
•Sell Excess Electricity to Secondary Market
.12
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 developer
Develop a long-term power purchase agreement
•Mechanism for third-party financing
•Minimizes market risks for initial units
