Achieving Competitive Levelized Cost of Electricity (LCOE)
Competitive LCOE range: $82-97/MWh
Key Assumptions: Fuel range = $4.00 - $10.0/MMBtu (NG); $2.20/MMBtu (Coal) CO2 price range = $0 - $30/ton Capacity factor = 92% (Large Nuclear and Coal); 95% (SMR); CCGT: 85% (Base Load); 40-60% (Intermediate Load) CAPEX range = $4600 - $6000/kW (Large Nuclear)
Minimize Overnight Cost
• Optimum power output (180 MWe)
• Simple standard plant layout and design
• Competitive global supply chain
• Innovative modularization
• Short construction schedule (3 years)
• Less than $5000/kW* for 360 MWe greenfield plant
Optimize Operating Costs
• “Plug and Play” design levers existing infrastructure
• 80%* reduction in security staff with normal DBTs
• 3 licensed operators/shift for “two-pack”
• Fleet O&M support enabled by standardization
• DCWG approach with IAC for utility-centric design

Licensing Strategy Lead Plant (TVA Clinch River): 10CFR50
First U.S. site-specific SMR license application
10CFR50 license approach lowers FOAK risk
• Targeting mid-2014 CPA submittal by TVA
• Enables design changes in construction
CP is opportunity to identify NRC issues early
Manage regulatory risk with early engagement
Subsequent Plants: 10CFR52 with DC/COLA
Gain DCD efficiency by levering PSAR work
Submit DCA during 4Q13
Target Design Certification by NRC in 2017
Resolve all known FOAK issues before filing DCA
• 24 topical & technical reports planned pre-DCA
• Continue aggressive pre-DCA NRC engagement
Prepare CPA

Events and Threats mPower Design Features
Earthquakes And Floods
• Seismic attenuation: Deeply embedded reactor building dissipates energy, limits motion
• “Water-tight” : Separated, waterproof reactor compartments address unexpected events
Loss of Offsite Power • Passively safe: AC power, offsite or onsite, not required for design basis safety functions
• Defense-in-depth: 2 back-up 2.50MWe diesel generators for grid-independent AC power
Station Blackout • 3-day batteries: Safety-related DC power supports all accident mitigation for 72 hours
• APU back-up: Auxiliary Power Units inside reactor building recharge battery system
• Long-duration “station keeping”: Space allocated for 7+-day battery supply for plant monitoring/control
Emergency Core Cooling
• Gravity, not pumps: Natural circulation decay heat removal; water source in containment
• Robust margins: Core heat rate (11.5kW/m) and small core (500MWth) limit energy
• Slow accidents: Maximum break small compared to reactor inventory (4.7x10-5m2/m3)
Containment Integrity and Ultimate Heat Sink
• Passive hydrogen recombiners: Prevention of explosions without need for power supply
• Internal cooling source: Ultimate heat sink inside underground shielded reactor building
• Extended performance window: Up to 14 days without need for external intervention
Spent Fuel Pool Integrity and Cooling
• Protected structure: Underground, inside reactor service building, located on basemat
• Large heat sink: 30+ days before boiling and uncovering of fuel with 20 years of spent fuel
Multi-layer defense … mitigates extreme beyond-design basis challenges
Protection against “Fukushima-type” Events
