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.

Long Island Power Study Points to Re-Powering, Not New Plants

LCG, August 6, 2002-C.W. Post's Center for Management Analysis released a study on Long Island, New York's power supply.

The report, developed at Long Island University's C.W. Post campus, comes to the conclusion that existing, old plants can be converted easily into combined cycle facilities, a process which could result in three times the current Long Island capacity.

According to Center for Management Analysis director Dr. Matthew C. Cordaro, as much as 4,700 new megawatts might be added through combined-cycle conversions.

Although the Center's study emphasizes bringing new technology to old plants, it also suggests that the completion of current New York power projects will prevent overextending the area's electricity capacity while improvements are made elsewhere.
