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.

Davis Says He'll Have 5,000 New Megawatts by July

LCG, Feb. 9, 2001California Gov. Gray Davis, in a news conference held at the construction site of a 545 megawatt power plant, said yesterday he would have 5,000 megawatts of new generation on line by July of this year and another 15,000 by July of 2004.

The new power plants were only part of a package of executive orders signed by the governor yesterday. In addition to directing regulators to speed up the licensing process for new plants something he ordered last fall with little effect he directed the California Air Resources Board to set up an emissions credit scheme that would allow merchant plant operators to pay into a fund in order to keep their plants running. Money in the fund would be used to install pollution mitigation equipment.

Not everyone was happy with the orders and no one seemed to know where 5,000 megawatts could suddenly be found.

The Sierra Club warned that Davis' plans could wipe out years of work done to clean up California air. "We must ensure we have aggressive energy conservation and efficiency," said spokesman Carl Zichella. "Get the cleaner power plants on line and prevent any increase in air pollution."

The governor's 5,000 megawatts includes two plants currently under construction by Calpine Corp., will have a combined capacity of about 1,200 megawatts. Of the remaining 3,800 megawatts, it appears Davis is hoping plans by the California Energy Commission to add 2,100 megawatts of small peaking facilities will work out.

So far, one such peaker out of a total of seven remains in development. The others were cancelled because of "not in my backyard" objections, which carry great weight in California.

The remaining 1,700 megawatts is to come from upgrades to existing plants and from renewable resources.
