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.

Drought Affects Output at Southeastern Power Plants

LCG, Aug. 27, 2002--Hydropower and fossil-fueled electric plants are being forced to cut their output as a drought is in its fourth year in the Southeastern U.S.

Some utilities that have been accustomed to selling excess power produced cheaply at hydropower facilities to others outside the region have cut production in order to be able to continue producing for their customers. Duke Energy and Carolina Power & Light have cut hydropower output by between 70 and 80 percent, as rivers and lakes are lower than normal by an amount equal to an entire year's rainfall.

Thermal plants running on coal, oil, natural gas or nuclear fuel are also restricted due to lower-than-average levels of cooling water. At a coal plant owned by Duke, the neighboring river is 25 feet below normal.

While hydroelectric facilities make up 1 percent of CP&L's generation portfolio, their relatively low cost means that the impact of the drought is disproportionately severe in terms of profitability.
