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 to Install 120 MW Temporary Capacity

LCG, May 29, 2003-Today the Long Island Power Authority announced that it will build temporary generating capacity to cover summer peak demand.

Six simple-cycle turbines will be mounted on trucks at the Holtsville and Shoreham substations. Each turbine has 20.5 megawatts of capacity and will be used to head off rolling blackouts in the case that demand exceeds available capacity.

Available capacity in the area is low for the summer. TransEnergie's 300-megawatt Cross Sound Cable has not been operative because regulations require such units to be buried more deeply. Also, Calpine Corporation's 45-megawatt Stony Brook plant will not be available.

The temporary turbines are likely to cost about $17 million.
