Recognizing their desirable attributes and long-term potential to meet data center demands for power, several technology companies have announced their intention to team up with nuclear developers. At the same time, three companies with shuttered nuclear plants have notified the U.S. Nuclear Regulatory Commission of their plans to restart those facilities, which were closed for economic reasons.

The U.S. Nuclear Regulatory Commission (NRC) has completed its draft safety evaluation (SE) a month ahead of schedule—albeit with open items—for TerraPower’s Kemmerer Power Station Unit 1, a pioneering 345-MWe sodium-cooled fast reactor (SFR) under development in Wyoming. Editor’s note: This article was substantially updated on Feb. 27 at 11 a.m. CST to provide deeper […]

Last Energy has formally launched the UK’s nuclear site licensing (NSL) process for plans to develop four 20-MWe microreactors in South Wales, becoming the first small modular reactor (SMR) developer to make the move. The UK Office for Nuclear Regulation (ONR) on Feb. 17 confirmed the U.S.-based nuclear technology firm’s entry into the critical licensing […]

Advanced nuclear technology firm Oklo is partnering with Texas-based prime and backup solutions company RPower to roll out an innovative “phased energy model” that will combine natural gas and nuclear to offer a scalable and sustainable turnkey solution for data centers. The companies on Jan. 17 said they signed a memorandum of understanding (MOU) to […]

DeepGEO, a multinational spent nuclear fuel (SNF) repository developer, and Copenhagen Atomics, a Danish advanced thorium reactor innovator, have signed a first-of-its-kind collaboration agreement that seeks to revolutionize the nuclear fuel cycle by aligning emerging waste management solutions with next-generation reactor technologies. The landmark collaboration marks an industry-first effort to unite a reactor designer and […]

As global nuclear ambitions surge, the industry’s fuel supply chain faces critical gaps. Can advanced fuels like HALEU (high-assay low-enriched uranium) and TRISO (TRi-structural ISOtropic particle fuel)

Ultra Safe Nuclear Corp. (USNC), a developer of much-watched microreactor technology and advanced nuclear fuel, has filed for Chapter 11 bankruptcy. The move signals a critical restructuring phase through which the company will seek to secure new ownership while ensuring uninterrupted operations. The company’s Oct. 29 filings at the U.S. Bankruptcy Court for the District […]

The U.S. Dept. of Energy (DOE) announced six companies have successfully bid to provide deconversion services for high-assay low-enriched uranium (HALEU) fuel to support advanced nuclear reactors. The DOE on October 8 announced the complete list of successful bidders. They include Nuclear Fuel Services, part of BWX Technologies (BWXT); American Centrifuge Operating, part of Centrus […]

The Nuclear Regulatory Commission (NRC) has granted Abilene Christian University (ACU) a construction permit to build its Molten Salt Research Reactor (MSRR) facility on the university’s campus in Texas. The approval is the regulatory body’s first for a liquid-fueled advanced reactor, the first for a research reactor in decades, and its second for any advanced […]

(Updated—June 1, 2024): Framatome and TerraPower will team to design and develop a pilot line for high-assay low-enriched uranium (HALEU) metallization, a crucial deconversion process, at Framatome’s nuclear fuel manufacturing facility in Richland, Washington. The pilot line, which will convert uranium oxide into HALEU metal, is scheduled to be ready for testing in early 2025, […]
