NuScale Power Corporation is a publicly traded American company that designs and markets small modular reactors (SMRs).

[3] The current scalable 77 MWe SMR VOYGR design was submitted for NRC review on January 1, 2023, and as of December 2023 was about a third complete.

[4] NuScale's SMR designs employ 9 feet (2.7 m) diameter by 65 feet (20 m) high reactor vessels that use conventional cooling methods and run on low enriched uranium fuel assemblies based on existing light water reactor designs.

Its coolant loop uses natural convection, fed from a large water reservoir that can operate without powered pumps.

The Oregon State team continued their work building a one-third scale test lab, while inheriting related patents from the university in 2007,[11][12] in exchange for an equity stake.

[17] In January 2011, NuScale's largest investor, Kenwood Group, was investigated by the U.S. Securities and Exchange Commission (SEC) and later pleaded guilty to operating a Ponzi scheme.

[13] According to The Energy Daily, Fluor's investment saved the company, which had been "financially marooned" by its prior investor.

[25] In the second round in December 2013, NuScale won up to $226 million in "cost-sharing" funding to share the expense of obtaining government approval, through the SMR Licensing Technical Support program.

[27][28] In September 2020, the U.S. Department of Energy reported that it had provided more than $400 million since 2014 to support the NuScale development and that of other earlier stage domestic SMR designs.

[33] UAMPS operates power plants in Wyoming, New Mexico, California, and Utah, selling to local utilities.

[34] The company submitted designs to the NRC in January 2017 for a 12 reactor power plant producing 570 MWe at a build cost under $3 billion.

[38] In April 2022, Doosan Enerbility was contracted to begin manufacturing power module components for CFPP.

Doosan Enerbility expected to reach full-scale production at their plant in Changwon, South Korea, in the second half of 2023.

[39][40] In January 2023, CFPP approved a new Budget and Plan of Finance, establishing a target price of $89/MWh (¢8.9/kWh) after an estimated $30/MWh generation subsidy from the 2022 Inflation Reduction Act (IRA).

[45][7] POWER magazine reported that the project had received $232 million of DOE financial support by the time it was cancelled.

[48] The following month, Energy Northwest said it had no immediate plans to construct a nuclear power plant, but had evaluated all the available SMR technologies and identified NuScale as the best available option.

[11] In January 2018, the NRC agreed that the passive safety features allow NuScale's SMR design to operate safely without back-up power.

[55] In February 2022, NuScale and mining conglomerate KGHM announced a contract to construct an SMR in Poland by 2029.

[61] On 25 July 2024, RoPower Nuclear and Fluor Corporation signed the second stage Front-End Engineering and Design (FEED 2) contract, for the planned SMR project in Romania which will provide updated cost estimate and other analysis for a final investment decision.

[75] In the event that power is lost for normal cooling systems, the water in the pool absorbs heat and boils.

[11] The pool stores enough water to safely cool the 77 MWe reactor design core for at least 72 hours without needing manual replenishment.

[85] The main issue was that in the event of an emergency shutdown condensed steam returning to the reactor vessel would be low in boron and might not absorb enough neutrons.
