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.

TransAlta Plant Expansion Approved

LCG, Feb. 14, 2002--TransAlta received approval from the Alberta Energy and Utilities Board Tuesday to double the capacity of the Keephills plant, 44 miles west of Edmonton.

The board said that the coal-fired plant can be expanded from two operating units to four, based on the condition that environmental design supports improved emission performance as regulations become more strict. TransAlta plans to consider whether it will move ahead with construction, and reach a decision regarding Keephills in the second quarter.

If the expansion took place, it would add 450 megawatts to Alberta's capacity by 2005. Generating companies in Alberta have complained that plant construction in Alberta's central area, where Keephills is located, is deterred by the lack of transmission infrastructure to the southern part of the province.
