This remarkable collaboration will strengthen supply chain capabilities as NuScale Power approaches commercialization

Grant secured through Commonwealth of Pennsylvania for work with Concurrent Technologies and North American Forgemasters

Today, NuScale Power and the U.S. Reactor Forging Consortium (RFC), comprised of North American Forgemasters (NAF), Scot Forge, and ATI Forged Products, announced they have signed a Collaboration Agreement to leverage the existing robust forging supply chain in the U.S., to prepare NuScale to deploy its small modular reactor (SMR) technology to customers worldwide and to support, retain, and expand U.S. manufacturing jobs.

The RFC is the combination of highly qualified expert suppliers of nuclear-grade forgings for the worldwide nuclear industry. The combined three companies act as the only fully integrated manufacturer of large alloy and stainless steel open die, seamless rolled ring, and large uniquely-shaped forgings (heads with integral nozzles) in the Western Hemisphere with as-forged piece weights exceeding 160 tons.

Under the Collaboration Agreement, the RFC and NuScale will cooperate in design for manufacturability reviews for forged geometries to reduce welding, chemical composition tailoring and optimized configuration for fabrication. The collaboration will support the U.S. supply chain planning as NuScale approaches near term commercialization of the NuScale Power Modules™ (NPM).

The Collaboration Agreement supports the U.S. Department of Energy’s (DOE) report released earlier this year, “America’s Strategy to Secure the Supply Chain for a Robust Clean Energy Transition,” designed to retain and develop U.S. jobs through the exploration of mutually beneficial domestic business relationships. This includes, but is not limited to, U.S. and State Government grants and funding opportunities, development of FC member company capabilities and capacities, and other U.S. manufacturing opportunities.

Consortium member NAF is currently partnering with Pennsylvania-based Center for Advanced Nuclear Manufacturing, operated by Concurrent Technologies Corporation (CTC), on a full production size shell research project that will focus on the use of austenitic stainless steel for reactor and containment vessels in SMRs and advance reactors. Financed in part by a grant from the Commonwealth of Pennsylvania, Department of Economic Development, NAF in collaboration with its joint venture owners Scot Forge and ELLWOOD Group, INC. will perform melting, forging, heat treating, rough machining, mechanical testing, and non-destructive testing while CTC oversees the development and performs independent technical evaluations of the forged material. This partnership will serve to create jobs by establishing a supply chain in Pennsylvania and ultimately benefit the overall development of SMRs and advanced reactor deployment.

The RFC partners are strategically located across the U.S. and are helping NuScale strengthen its U.S. supply chain. NAF has its principal office in New Castle, Pennsylvania; Scot Forge is headquartered in Spring Grove, Illinois; and ATI Forged Products has its office in Cudahy, Wisconsin. NAF, Scot Forge, and ATI have previously worked collaboratively on the refinement of designs and manufacturing feasibility of large nuclear grade forgings for the NPM.

About NuScale Power

NuScale Power is poised to meet the diverse energy needs of customers across the world. It has developed a new modular light water reactor nuclear power plant to supply energy for electrical generation, district heating, desalination, hydrogen production and other process heat applications. The groundbreaking NuScale Power Module™ (NPM), a small, safe, pressurized water reactor, can generate 77 MWe of electricity and can be scaled to meet customer needs. The VOYGR™-12 power plant is capable of generating 924 MWe, and NuScale also offers four-module VOYGR-4 (308 MWe) and six-module VOYGR-6 (462 MWe) plants and other configurations based on customer needs. The majority investor in NuScale is Fluor Corporation, a global engineering, procurement, and construction company with more than 70 years supporting nuclear projects.

NuScale is headquartered in Portland, Ore. and has offices in Corvallis, Ore.; Rockville, Md.; Charlotte, N.C.; Richland, Wash.; and London, UK. Follow us on Twitter: @NuScale_Power, Facebook: NuScale Power, LLC, LinkedIn: NuScale-Power, and Instagram: nuscale_power. Visit NuScale Power's website.

On December 14, 2021, NuScale announced a definitive business combination agreement with Spring Valley Acquisition Corp. (Nasdaq: SV, SVSVW). Upon the closing of the business combination, NuScale will become publicly traded under the new ticker symbol “SMR.” Additional information about the transaction can be viewed here: https://www.nuscalepower.com/about-us/investors

About North American Forgemasters Company

NAF is a 50/50 joint venture between two privately owned 100% domestic companies, Scot Forge and ELLWOOD Group, Inc. In 2015 NAF commissioned its 10,121T open die forging press aimed at expanding the domestic capabilities and capacity for the ultra large forgings required for the advanced reactor market. NAF produces forgings too large for its JV owners ranging from as-forged weights starting at approximately 100,000 lbs to exceeding 320,000 lbs. Furthermore, NAF’s strategic location takes advantage of the ingot steelmaking facility (ELLWOOD Quality Steels) located within the same complex. The molten metal now solidified is kept hot and at NAF is forged into rings, shells, discs, heads and custom forged shapes. Located in western Pennsylvania, NAF serves as the only fully integrated manufacturer of ultra large open die forgings in the Western Hemisphere. NAF, through the continuous investments made by its JV owners, represents American manufacturing at its finest. Learn more at www.naforgemasters.com.
