1 Nuclear Energy for Remote Applications 23 October, 2014 Michael Kuca (University of Alaska) Vishal Patel (Texas A&M) Alana Vilagi (University of Alaska) 1

2 Objectives Consider GenIII+/GenIV nuclear power plants for remote applications ACEP INL/CSNR collaboration: POLAR design team Taylor Duffin (University of Utah) Michael Kuca (University of Alaska) Haley McIntyre (University of Alaska) Christopher Morrison (Rensselaer Polytechnic Institute) Vishal Patel (Texas A&M) Alana Vilagi (University of Alaska) Opportunities and Obstacles to deployment 2

3 Fuel Supply Chain; Consumer Costs AK utilities: $0.20 to $1.30 per kwh Remote fuel price:$5 to $10 per gallon ISER (2010) Alaska Dispatch (2012) 3

4 Technology: Big Picture INL (2013) 5

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

6 CSNR ACEP Collaboration CSNR: mini reactors for space exploration Some aspects apply to northern deployment Design a mini Gen IV mobile reactor Parameters o o o o o Safe Transportable Passive cooling, Non-pressurized vessel Less than 10 MWe Long life 8

7 POLAR Passively Operated Lead Arctic Reactor 15MWth/5MWe PbBi cooled, natural circulation Core Outlet Temp 550 C Open air Brayton Cycle 500 C Ship weight 100 ton 9

8 POLAR Lifetimes at 5 MWe Case Approximate Lifetime (years) W-Cermet Fuel Loading 1 6 W-Cermet Fuel Loading 2 10 SiC Fuel 15 UZr Fuel 20 10

9 Process Heat Applications Application Temperature Range (Celsius) Fish Processing Greenhouse District Heating Desalination Biomass to Biofuels Oil Production Coal to liquid fuels Hydrogen Production

10 Process Heat Applications 0 C 1000 C 12

11 Licensing Issues for SMRs Deterministic focus on Light Water Reactors Staffing: 4 operators per shift for total Core Damage Frequency Possible Strategies for Gen IV New Regulations time consuming Exemptions complex Risk-Informed Performance-Based Licensing 13

12 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 14

13 NRC Licensing Timeline 15

14 Alaska Sustainable Energy Act 2010 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 16

15 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 17
