X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Regulators Disappoint Watchdog in First Energy Case

LCG, Sept. 14, 2000The Public utilities Commission of Ohio has reaffirmed its approval of the "transition plan" proffered by First Energy Corp., and in doing so has upset a local watchdog group which says it will go to court.

Among the things that Citizen Power doesn't like is a provision in First Energy's plan that allows the company to count its affiliate First Energy Services as a competitive supplier, which makes it easier for the company to achieve a 20 percent threshold for customers switching electricity providers.

The reason Citizen Power doesn't like that provision is its beneficial (to the company) effect on stranded cost recovery. The regulators dismissed the watchdog's complaint on that issue saying if the legislature had intended to preclude switches to an affiliate of a utility it would have said so.

The order also rejected Citizen Power's arguments that First Energy should not be allowed toexclude nearby suppliers' access to 1,120 megawatts of generation capacity, and that First Energy must give up control of the transmission lines to an independent operator before competition starts.

David Hughes, executive director of Citizen Power, complained "PUCO failed to respond (positively) to a single argument we made on these important issues."

Harvey Reiter, the watchdog's lawyer, said "Citizen Power does not believe PUCO's orders are logically supportable and it intends to go to court."
