The NuScale small modular reactor plant program is a series of nuclear power plants built around NuScale’s 77 megawatt module, and its largest US prospect, up to 6 gigawatts for the Tennessee Valley Authority through ENTRA1 Energy, remains a nonbinding agreement with no power purchase agreement signed.
NuScale Small Modular Reactor Plants Gain a Romanian Investment Decision as Fluor Exits Its Stake
Fluor sold its last NuScale shares in April 2026 but remains the preferred construction partner, and Romania approved a final investment decision in February for a six module, 462 megawatt plant. In South Carolina, the Westinghouse LEU+ fuel facility expansion won a 40 year county tax package on October 20.
Project Overview
- Project Name: NuScale small modular reactor power plants (VOYGR)
- Technology: NuScale 77 megawatt power module, with a six module plant rated at 462 megawatts, and the uprated module approved by the US Nuclear Regulatory Commission in May 2025
- US Prospect: Up to 6 gigawatts across the Tennessee Valley Authority region, developed by ENTRA1 Energy under a September 2025 agreement
- US Status: Agreement is nonbinding, and NuScale said in its second quarter 2026 results that ENTRA1 and TVA were still working toward a definitive power purchase agreement
- Romania Project: Six NuScale modules totaling 462 megawatts at the former Doicesti coal plant, with shareholders of Nuclearelectrica approving a final investment decision on February 13, 2026
- Romania Cost and Timing: The Romanian Prime Minister cited a cost of $6 billion to $7 billion and said investment would proceed once a funding formula is found
- Engineering and Construction: Fluor, as preferred partner and lead on the Doicesti design work
- Design Support: Sargent & Lundy, under the 2020 collaboration agreement with Fluor
- Fluor Equity: Fluor completed the sale of its remaining NuScale shares in April 2026
- NuScale Finances: Second quarter 2026 revenue of $75,000 and about $1.9 billion in cash, per press coverage

Reported 17th November 2020: New Carbon-Free small modular nuclear reactor plants are set to be built in North America. This is after Fluor Corporation announced that the company has reached an agreement with Sargent & Lundy to collaborate with joint marketing and design services for the execution of the nuclear reactor plants.
Under the new agreement with Sargent & Lundy, Fluor will design the turbine island and balance-of-plant facilities with Sargent & Lundy providing the design for the nuclear island.
NuScale’s groundbreaking Nuclear Regulatory Commission-certified technology is the world’s first and only small modular reactor to gain design certification approval by the US Nuclear Regulatory Commission. Sargent & Lundy and NuScale agreed to work together in late July 2019 with Sargent & Lundy providing standard plant design services as well as architect-engineering support.

Bringing new carbon-free energy to the US
According to Alan Boeckmann, Fluor’s executive chairman, Fluor has been a leader in serving the nuclear industry for more than 70 years including the design and construction support for more than 25 units, plus nearly 100 million hours of operations and maintenance work. “This collaboration agreement with one of the most respected companies serving the nuclear power industry brings nearly 150 years of combined experience and further solidifies the opportunity to bring new carbon-free energy to the US and North America,” he added.
Sargent & Lundy Chairman, President and Chief Executive Officer Thomas R. White said that the opportunity to team with NuScale and Fluor for the design and construction of small modular reactor plants further extends Sargent & Lundy’s history of being at the forefront of nuclear new generation design. “We’re excited to support NuScale’s groundbreaking technology – a simplified, scalable, resilient design that is poised to support global demand,” he affirmed.
In addition to previously announced strategic partners and investors in NuScale, which includes Sargent & Lundy, Fluor and NuScale continue to engage with potential customers, capital investors, manufacturers and other supply chain partners for new small modular reactor development efforts.
