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.

Peabody's Thoroughbred Energy Campus Permit in Limbo

LCG, August 17, 2005--Development plans for Peabody Energy's Thoroughbred Energy Campus, a proposed 1,500-MW, coal-fired power plant hit a snag last week when a Kentucky hearing officer recommended that its permit be withheld until a number of items are resolved. The project is located near Central City, Kentucky and would be supplied by coal from an adjacent mine.

In her 400-page report, hearing officer Janet Thompson found that the Kentucky Division of Air Quality erred in granting the permit and recommended that the air permit for the plant be sent back to regulators for further evaluation of a number of issues, including how emissions might affect animals and consideration of technologies that would reduce emissions to lower levels.

Parties have two weeks to submit comments on the report and recommendations. A Peabody spokesperson stated that its response would be put in writing shortly. Environmental and Public Protection Cabinet Secretary LaJuana Wilcher will review the report, recommendations and comments and will then decide whether to accept some or all of them, or call for further hearings. Parties may then appeal Wilcher's findings to the Franklin Circuit Court.
