The US Department of Energy selected the Tennessee Valley Authority (TVA) and Holtec Government Services to receive up to $800 million in combined federal cost-shared funding — $400 million each — to accelerate deployment of advanced light-water small modular reactors (SMRs). TVA's award backs a GE Vernova Hitachi BWRX-300 unit at the Clinch River site in Oak Ridge, Tennessee, targeted to be the nation's first commercial SMR (commercial operation targeted early 2030s), with domestic supply-chain partners Scot Forge, North American Forgemasters, BWX Technologies and Aecon. Holtec's award backs deployment of two SMR-300 units at the Palisades Nuclear Generating Station site in Covert, Michigan. The program is intended to expand US SMR manufacturing capacity and seed follow-on domestic and export supply chains.

Analyst notesShow

Mechanism

DOE cost-shared federal grant funding (up to $400M per project, $800M combined) awarded under the Department's SMR deployment support program to two separate utility-led project teams. This is direct capital de-risking for first-of-a-kind commercial SMR construction rather than R&D funding — both projects target near-term construction and grid connection (TVA's Clinch River BWRX-300 aims for commercial operation in the early 2030s). The award explicitly names domestic forging and heavy-manufacturing suppliers (Scot Forge, North American Forgemasters, BWX Technologies, Aecon), signalling an intent to seed a reshored SMR component supply chain rather than fund a single plant in isolation.

Downstream implications

First subsidized path to a commercially operating SMR in the US;

successful delivery would be a reference case other utilities and export markets (Holtec markets SMR-300 internationally) could point to.

Concentrates near-term US SMR heavy-forging demand on a small number of

domestic suppliers (Scot Forge, North American Forgemasters, BWX Tech), a potential bottleneck if multiple follow-on SMR orders materialize.

Complements the broader 2025-26 US nuclear-acceleration push (executive

orders, NRC licensing reform) — this action is the capital layer.

Open questions

Final cost-sharing split (DOE vs. TVA/Holtec/private co-investment) and

total project cost were not fully disclosed at announcement.

Timeline risk: BWRX-300 and SMR-300 are both first-of-a-kind builds in

the US regulatory environment; schedule slippage is the primary risk to the "first commercial SMR" framing.
