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.

Federal Appeals Court Reverses EPA Air Emission Standard in Alabama

LCG, March 7, 2013--The United States U.S. 11th Circuit Court of Appeals yesterday ruled in favor of Alabama Power (a Southern Company subsidiary) and against the U.S. Environmental Protection Agency (EPA) over industrial air emission standards.

In 2008 the EPA approved changes in Alabama?s rules regarding smoke emissions at industrial plants and the allowable frequency of emitting opaque smoke; however, the EPA reversed the rule changes in 2011, stating there was "sufficient likelihood" that the new rules would increase air pollution.

The three-member federal appeals court in Atlanta yesterday struck down the EPA's reversal, stating, "We conclude the 2011 disapproval was unauthorized by the Clean Air Act because the EPA failed to make the statutorily required error determination."
