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.

Bowie Power Station Receives Last Environmental Permit

LCG, Mar. 31, 2003--An air quality permit has been granted to a planned 1,000-megawatt power plant being developed by the SouthWestern Power Group in Bowie, Arizona.

The permit is the first of its kind issued by the Arizona Department of Environmental Quality (ADEQ) in three years, and is the final such permit necessary before construction of the Bowie plant can begin. Other permits included the Aquifer Protection Permit last year. The Bowie plant will use wet cooling, and will minimize the use of water by zero liquid discharge. Evaporative cooling will keep efficiency relatively high even during hot summer temperatures.

The configuration of the plant is to be combined-cycle, with two phases planned. The first 500 megawatts should be installed beginning this year, with operation in late 2005. The second phase is expected to come online in 2006.
