Gen III+ iPWR • Integrates steam generator
into pressure vessel • Passive designs remove
decay heat • US Modular design
compliments macro-grid
Technology: Small and Mini
7
Gen IV reactors • Alternative cooling designs • Factory sealed, no refueling • Individual units compliment
micro-grid
Examples (MWe) Sodium Toshiba 4S – 10 Pb-Bi G4M – 25 LFR SSTAR - 20
Examples (MWe) NuScale - 45 mPower - 225 CAREM – 25 KLT-40S - 10

► CSNR: mini reactors for space exploration • Some aspects apply to northern deployment
► Design a mini Gen IV mobile reactor • Parameters
o Safe o Transportable o Passive cooling, Non-pressurized vessel o Less than 10 MWe o Long life

► Deterministic focus on Light Water Reactors • Staffing: 4 operators per shift for total 40-80 • Core Damage Frequency
► Possible Strategies for Gen IV • New Regulations – time consuming • Exemptions – complex • Risk-Informed Performance-Based Licensing

► Preferred licensing strategy for the Next Generation Nuclear Plant project
► Review process that emphasizes outcomes rather than prescriptive methods for achieving them, providing more flexibility in design
Risk-Informed Performance-Based Licensing

► Gave Legislature authority to designate land in state for nuclear facility based on economics
• Health and public safety NRC jurisdiction
► The Department of Environmental Conservation shall
adopt regulations governing the issuance of nuclear facility siting permits
• Authorization program has not been created
► Require municipal approval
Alaska Sustainable Energy Act 2010

• Remote nuclear power plants may be viable in 2020s • Continue UA R&D Partnerships
• Lack of super utility; promote stakeholder alliance – Military, Civilian, Industry – Communicate with state and federal legislators
• Licensing challenges are not insurmountable – Early site permitting – Siting facilitated through legislature
• Initial capital investments – First of a kind funding – Master Limited Partnership
Conclusions
