Simple solution to plant safety and O&M functions

Nuclear Island fully underground

• Lower overall seismic response

• Greater protection from external threats

Passive safety systems

• Passive cooling – AC power not required for

safety functions

• 72-hour battery supply for monitoring/control

• 14-day SBO coping time w/o outside intervention

• No Shared Safety Systems

Enhanced spent fuel pool configuration

• 20-year storage capacity

• Underground, inside protected structure

• Large heat sink, 30+ days boil-off protection

Nuclear Island Features


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

*Current estimates

LCOE Comparison US


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

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
