The Tennessee Valley Authority (TVA) has signed a first-of-its-kind power purchase agreement (PPA) with advanced nuclear technology firm Kairos Power to buy power from the company’s planned Hermes 2, a molten salt nuclear reactor in Oak Ridge, Tennessee. The deal makes TVA the first U.S. utility to contract for electricity from a Gen-IV reactor. Under […]

Centrus Energy has produced and delivered 900 kilograms (kg) of High-Assay, Low-Enriched Uranium (HALEU) to the U.S. Department of Energy (DOE), completing Phase II of its pioneering enrichment contract with the agency. The shipment marks the first significant domestic production of HALEU—a specialized fuel required for many advanced reactors now under development—and stands as a […]

The U.S. Air Force has formally reaffirmed its selection of Oklo’s liquid metal-cooled fast reactor to provide nuclear energy at Eielson Air Force Base in Alaska, re-issuing a Notice of Intent to Award (NOITA) for the company’s Aurora Powerhouse following a comprehensive evaluation process. The June 10 announcement, issued by the Defense Logistics Agency Energy […]

In a critical step aimed at bolstering advanced reactor development and their domestic nuclear fuel readiness, the U.S. Department of Energy (DOE) has issued its first round of allocations for high-assay low-enriched uranium (HALEU) under its HALEU Availability Program to five American nuclear developers. On April 9, the DOE said it made conditional commitments to […]

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)
