TVA, Holtec Gain $800M US Funding For Small Nuclear Reactor Builds

Small modular nuclear energy reactors utilizing mild water cooling know-how to be developed for U.S. business use by energy supplier Tennessee Valley Authority in its multi-state area and by personal developer Holtec Worldwide in Michigan will acquire as much as $400 million every in federal cost-share funds to advance initiatives and associated provide chains, the U.S, Power Dept. introduced this month.

Power Secretary Chris Wright mentioned the undertaking investments in third-generation nuclear energy know-how will assist advance Trump administration targets outlined earlier this 12 months to spice up that vitality supply domestically—notably to insure U.S. vitality safety and acquire international synthetic intelligence dominance. “Superior mild water SMRs will give our nation the dependable, round the clock energy we want … assist knowledge facilities and AI development, and reinforce a stronger, safer electrical grid,” he mentioned. 

The funding truly stems from a Biden-era solicitation launched in October 2024 utilizing 2021 federal infrastructure act funding that features one other $100 million to be awarded later this 12 months to assist extra deployments and tackle obstacles in design, licensing, provide chain and website readiness, mentioned DOE. However the Trump administration revised the solicitation final spring to take away required group profit monetary investments by winners.  

DOE funding will help TVA to construct the primary two-unit, estimated 600-MW GE Vernova Hitachi BWRX-300 SMR at its Clinch River website in Tennessee by the early 2030s and plan future deployments with companions Indiana Michigan Energy and BWX Applied sciences. The TVA growth group additionally contains contractors Bechtel and Ontario-based Aecon, Duke Power, Oak Ridge Related Universities and the Electrical Energy Analysis Institute.

TVA’s building allow utility to the U.S. Nuclear Regulatory Fee for the BWRX-300 at Clinch River, submitted in Might, nonetheless is beneath company overview. “This award affirms TVA’s continued management in shaping the nation’s nuclear vitality future,” mentioned Don Moul, TVA president and CEO of the impartial federal company company that provides energy to 10 million folks in most of Tennessee, northern Alabama, northeastern Mississippi, southwestern Kentucky and smaller areas of neighboring states.

“In contrast to earlier nuclear building initiatives within the U.S., contractors will work with [GE Vernova Hitachi Nuclear Energy] and TVA as a extremely built-in undertaking group to plan, design and probably procure, assemble and fee Clinch River Unit 1.” Bechtel mentioned in January. “The built-in undertaking supply mannequin is the popular technique that may make our undertaking a real group effort,” mentioned Bob Deacy, TVA senior vp and its Clinch River undertaking chief. “We are going to actively work collectively towards a goal funds and schedule – creating a big benefit to drive nuclear innovation, share dangers and scale back prices.”

TVA additionally has signed public-private partnerships with different SMR builders in latest months, together with Kairos Energy and NuScale, in addition to with nuclear fusion developer Sort One Power. TVA mentioned it at the moment has about 11 GW of requested load for AI and knowledge facilities throughout its space, together with from Google, Meta and xAI.   

TVA’s know-how collaboration associate Ontario Energy Era has began building of 4 GE Vernova BWRX-300 models, with the primary to be on-line by 2030 at its Darlington energy plant. The province accredited building plans and awarded a contract in Might to a partnership between Aecon and Kiewit Nuclear Canada for building planning and execution, and undertaking administration. Aecon mentioned its share of the contract is price about $930 million.

GE Vernova Hitachi Nuclear Power and design-build agency Samsung C&T in October additionally introduced a strategic alliance to advance BWRX-300 SMR deployment in markets exterior North America.

Going Modular in Michigan

Holtec’s funding will help firm plans to deploy its dual-unit SMR-300 reactors on the website of the 800-MW Palisades nuclear energy plant it owns and in addition seeks to restart in January in Covert, Mich., including a further 600 MW. The developer additionally signed an expanded alliance settlement with Hyundai Engineering & Development to construct a 10-GW fleet of SMR-300s in North America via the 2030s, starting with the Palisades undertaking. The contractors will handle reactor building, deployment, operation, provide chain and energy promoting. Venture value has been estimated at $2.1 billion to $2.7 billion per reactor.

“Focusing on first energy by 2030, our Mission 2030 initiative will place the Palisades SMR undertaking because the reference plant for all future SMR-300 deployments—domestically and globally,” mentioned Holtec. 

Firm founder, chairman & CEO Krishna Singh instructed attendees of an American Nuclear Society convention final month that the corporate’s SMR-300 reactor “was born the day after” the 2011 Fukushima nuclear plant meltdown in Japan, but it surely didn’t win DOE funding on the time due to company disagreement on its design. Holtec self-funded the undertaking, Singh famous, and can submit its design subsequent 12 months to the U.S. Nuclear Regulatory Fee for restricted work authorization. 

In accordance with a Holtec assertion, “DOE’s assist is a vital enabler of the Palisades SMR-300 undertaking, transferring it from growth to deployment by constructing on the federal government’s prior assist” beneath the company’s Superior Reactor Demonstration Program relationship to 2020.

Holtec additionally has a $1.52-billion conditional mortgage from DOE for the Palisades restart, though the motion faces new litigation from anti nuclear teams which have sued the developer and the fee in federal courtroom.

Different lead candidates for the $900-million SMR federal funding included utility Arizona Public Service and developer Constellation, based on media experiences. The latter additionally closed a $1-billion DOE mortgage final month to restart the undamaged 835-MW reactor unit on the Three Mile Island nuclear energy plant in Pennsylvania.
