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.

Nevada Power's Chuck Lenzie Generating Station Fully Operational

LCG, April 19, 2006--The Nevada Power Company, a subsidiary of Sierra Pacific Resources, announced yesterday that the second of two, 580-MW, electric generating plants at the Chuck Lenzie Generating Station has commenced commercial operations well ahead of the June 30, 2006 target.

The new, gas-fired, Chuck Lenzie Generating Station is located about 20 miles northeast of Las Vegas in the Moapa Valley. Each of the two plants at the station includes two combustion turbines, a steam turbine and two heat recovery steam generators operating in combined-cycle mode. The station receives gas from the Kern River Pipeline.

The facility, formerly known as the Moapa Power Plant, was purchased from Duke Energy Corporation in October 2004, when the project was about 50% complete. In an order related to the plant, the Public Utilities Commission of Nevada (PUCN) allowed for an additional one percent rate of return incentive for timely completion of the plant. Specifically, the plant's two units were to be on line by March 31, 2006, and June 30, 2006.
