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.

FERC Holds Hearing over Contested Nevada Power Contracts

LCG, April 24, 2003The Federal Energy Regulatory Commission will determine whether or not to use recent market reports in deciding the fate of long-term power contracts in Nevada.

At the end of last year, a FERC administrative law judge suggested filings by Western states be thrown out because market manipulation effects were not significant enough during the Western power crisis to warrant the rewriting of contracts. Nevada Power, along with municipal utilities from Washington and California, complained that their long-term contracts to purchase power were unfairly costly since they were made at a time when electricity prices were possibly falsely inflated.

The contracts in question were made with Enron Corp., El Paso Corp, BP Plc, Allegheny Energy, and Mirant Corp.

The legal climate changed when FERC staff released a report March 26 that detailed widespread market manipulation during the California power crisis of 2000/2001.

Now utilities want to bring the FERC report into consideration regarding the decision over whether or not to rewrite contracts.

Energy companies find the request unreasonable and believe that FERC should not protect utilities from bad decisions such as signing costly contracts. They warn that a legal outcome in favor of the utilities may have serious and devastating effects on Western energy markets, especially in terms of new investment.

Utilities find that in desperation they were forced into expensive contracts because of serious lack of capacity and high prices, and many have asserted that their customers are suffering because of what they say are high costs resulting from fraudulent behavior. Utilities also noted that FERC advised utilities to sign long-term contracts during 2001 in order to avoid astronomical short-term electricity prices.

FERC is also reviewing contracts made by Washington municipal utility district Snohomish and Southern California Water Company, and heard arguments yesterday.
