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.

Energy Market May Lead to Mothballing of 16 AEP Texas Plants

LCG, September 12, 2002-American Electric Power, or AEP, may mothball as many as 16 of its Texas power plants in order to ease its financial situation.

The plants, all of which are gas-fired, are located within the Electric Reliability Council of Texas (ERCOT). ERCOT will determine which plants are RMR, or "reliability must run," and the remaining, less-than-vital plants will be pulled off line by the end of this year.

AEP officials say the mothballing is in response to deregulation-related growth in the Texas power industry, which has pushed wholesale electricity prices below AEP production costs. Plant employees affected by mothballing will reportedly assume inactive status and receive severance pay.

The sixteen plants in question, representing some 2,663 megawatts of capacity, are Abilene, B.M. Davis, E.S. Joslin, Fort Phantom, Fort Stockton, J.L. Bates, La Palma, Lake Pauline, Laredo, Lon C. Hill, Nueces Bay, Oak Creek, Paint Creek, Rio Pecos, San Angelo, and Victoria.
