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 Wants DOE Order to Switch on Cable

LCG, Aug. 15, 2002--With demand for power on Long Island straining available power capacity, the Long Island Power Authority is asking the Department of Energy to order a transmission cable to Long Island from Connecticut be turned on.

The request is not routine, in that the DOE rarely grants intervention on behalf of states. Some LIPA staff are warning that with unexpectedly high demand compared to last year, region-wide blackouts could occur if the cable is not activated. Connecticut's attorney general, Richard Blumenthal, has said that regardless of the supply situation on Long Island, Connecticut should not be forced to allow transmission of up to 330 megawatts of power across the Long Island Sound.

The New England Independent System Operator supports the New York position, while Connecticut's governor John G. Rowland has delayed the cable's operation, on the grounds that environmental reviews should be completed to determine possible effects on sea life on the bed of the sound. The cable's owner, TransEnergie, a subsidiary of Hydro-Quebec, cooperated with a request for more environmental reviews before operating the cable, which was not buried to the depth that was previously thought necessary not to disrupt sea life. The cable could otherwise be brought into operation within eight hours following an order.

The Department of Energy is seeking comment from grid operators and stakeholders before issuing a response to the LIPA's request.
