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.

Wait 'Til Next Year for New EPA Power Plant Rules

LCG, Nov. 12, 2001--The U.S. Environmental Protection Agency said Friday it will likely miss its self-imposed year-end deadline for issuing stricter power plant air pollution standards.

New proposals from the Bush administration are also being awaited by the Senate Environment and Public Works Committee headed by Sen. James M. Jeffords, the Independent from Vermont. The committee has said it will move ahead with legislation calling for cuts of at least 75 percent in power plant emissions.

A recent EPA study supported claims by U.S. utilities that the proposed limits on carbon dioxide, sulphur dioxide, nitrogen oxides and mercury would increase the cost of power by more than a third and have a calamitous effect on the U.S. economy.

Last week, Bill Harnett, a division director of EPA's Office of Air Quality Planning and Standards, told a meeting of the National Coal Council that the EPA would likely issue its new standards early next year.

Jeffords wants the 75 percent emissions cuts in place sometime in the coming year, but the Bush administration said last week it will oppose the legislation. The administration would regard carbon dioxide as a non-pollutant and provide trading mechanisms for the other three.
