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 $961 Million Rate Hike Not Half Enough;Casino Operators Balk at Prospect of $1 . Billion More

LCG, Dec. 28, 2001--Nevada Power Co., which has asked state utility regulators for a whopping $961 million (as in $0.96 billion) rate increase could be back asking for another rate hike of about $1 billion a year from now, the Las Vegas Review-Journal reported yesterday.

Casino operators, who are pretty good on figuring the odds, think it could happen and are unhappy about it.

The Nevada Energy Buyers Network, which represents casinos and other commercial customers, questioned the way Nevada Power based part of its proposed rates on future costs. The utility has based those costs on prices in contracts for wholesale power it either can't or chooses not to generate itself.

Nevada Power is confident it can renegotiate contracts with wholesale power providers so that it will pay less than the contract terms. Based on those assumed renegotiations, Nevada Power projects that its "going forward" cost should be 5.4 cents per kilowatt hour. But other utility documents show the rate should be 11.8 percent per kilowatt hour, the paper said.

The difference between the two is about $1.05 billion in annual revenue for Nevada Power.

Steve Boss, president of the buyer's network, said "The magnitude of the increase is a substantial financial impact on our clients, and our clients want to make sure in fact that the costs were prudently incurred as required (under state law)."
