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.

NRG, Dynegy Acquire Two Plants from Nevada Power

LCG, Nov. 20, 2000--NRG Energy Inc. and Dynegy Inc. announced jointly this morning that they will purchase two Las Vegas-area power plants with a combined capacity of 1,330 megawatts from the Nevada Power Co. subsidiary of Sierra Pacific Resources.

The 740 megawatt Clark Generating Station located in southeastern Las Vegas consists of 10 natural gas-fired units that can burn fuel oil as a backup.

The 605 megawatt Reid Gardner Generating Station, located 52 miles northeast of Las Vegas, consists of four baseload coal-fired units. Three 110 megawatt units are wholly owned by Nevada Power while a fourth 275 megawatt unit is jointly owned by Nevada Power and the California Department of Water Resources.

NRG and Dynegy will acquire Nevada Power's 85 percent interest in the fourth Reid Gardner unit and the California water agency will retain its 15 percent interest.

The sale of generation assets is a regulatory condition of the 1999 merger between Sierra Pacific Power Co. and Nevada Power Co. that formed Sierra Pacific Resources. Last month, NRG was named the successful bidder for Sierra Pacific's 50 percent interest in the 522 megawatt coal-fired North Valmy Generating Station and 100 percent interest in 25 megawatts of peaking units in northern Nevada.

The acquisition of Clark and Reid Gardner includes a transitional power purchase agreement for Nevada Power to purchase energy and ancillary services until March 1, 2003 under a contract the companies say will help provide price stability for its customers throughout the transition to an open market in Nevada.

The transaction is subject to approvals from the Federal Trade Commission, the Federal EnergyRegulatory Commission and the Nevada Public Utilities Commission. It is expected to close duringthe second quarter of 2001, the companies said.
