NuScale Power Technology: Expanding the Reach of Nuclear Energy Michigan Energy Symposium Combating Climate Change September 27, 2016

Energy and climate change Imperatives 7000 2005 U.S. CO2 Emissions (Tg) For the country: Maximize use of all clean energy sources Electrify the transportation sector Develop clean processes for liquid fuels and petrochemicals 6000 5000 Electricity 4000 3000 Transportation For nuclear energy: Reach more utilities Reach more process heat consumers Electricity contributes ~40% of US emissions Last time the US emitted 2050 goal (1000 Tg) was 1906 2000 2050 Goal Industrial 1000 Residential Commercial Misc

Reaching new customers Target customers… Smaller utilities with low capitalization/demand Larger utilities with small load growth Sites/facilities with special power requirements Non-electrical energy users (process heat) Will have new requirements… Enhanced safety margins High reliability and resilience to upsets Affordability and competitive power price Flexible deployment and operations That will require new designs… Simplified systems Multi-module plants Factory fabrication

The NuScale solution Enhanced safety Enhanced affordability integral design and natural circulation to eliminate major accident scenarios passive safety systems and extended cooling Enhanced affordability small initial capital cost staggered build-out options to reduce investment risk competitive power cost through design simplifications and factory fabrication Enhanced flexibility small module size (50 MWe) to better track power demand growth adaptability to nonelectrical applications

Nuclear power: not just for electricity

NuScale co-generation studies Oil Refinery Study Reducing Carbon Emissions (with Fluor) Hydrogen Production Study High-Temp Steam Electrolysis (with INL) 10-Module Plant coupled to a 250,000 barrels/d refinery, thus avoiding 190 MT/hr CO2 emissions 6-Module Plant producing 200 tons/d hydrogen for mid-sized ammonia plant entirely carbon free Integration with Wind Study Horse Butte Site (with UAMPS and ENW) Desalination Study Supporting a 300,000 City (with Aquatech) 1-Module balancing output of UAMPS 58 MWe wind farm 8-Module Plant producing 50 Mgal/d of clean water plus 340 MWe clean power Enabled by robust design and modularity of plant Demonstrated that supporting these applications is technical feasible and economically attractive in some regions Political and social acceptance has to be assessed on case-by-case basis

MISSION CRITICAL FACILITY Secure, reliable power Highly reliable power is required for mission-critical facilities. Hospitals, data centers, government facilities, banking or retail systems Security systems, telecommunications, air traffic control Safety systems for conventional Nuclear Plants Process failure can cause significant financial or reputational damage to the organization or may impact national security or safety UTILITY MACROGRID 570 MWe > 95% Capacity NuScale 12-Module Plant MISSION CRITICAL FACILITY DEDICATED MICROGRID 100 MWe > 99.99% Reliability for 60 years

Small Modular Reactors End game: hybrid energy systems Wind Turbines Electrical Storage Photovoltaic Solar Electricity Power Conversion Small Modular Reactors Desalination Plant Clean Water Holy Grail of energy systems: Each generator and each product process running in its “sweet spot” of performance. Provides optimal usage of natural resources and produces highest value products. Is a long-range vision: Start with one-on-one integration studies of NuScale plant with different generators and processes. Concentrated Solar Thermal Storage Petrochemical Plant Liquid Fuels
