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.

US GAO Affirms CA Crisis Related to Shortage

LCG, June 25, 2002-The United States General Accounting Office released a report yesterday which finds that the California energy crisis was due to a lack of capacity in the state.

Politicians have disagreed over the origin of the California crisis, and recently exposed market manipulation pratices have set politicians' fingers pointing at energy companies.

The GAO report asserts that market manipulation alone did not result in the crisis and that the state had a higher demand than supply.

The report also pointed out that new generation was built in other deregulated sates, such as Pennsylvania and Texas, at a much higher rate relative to forecasted need than that in California. Through 2001 California built a quarter of its forecasted capacity needs, while Texas built more than twice is forecasted capacity need.

The GAO included several reasons for a lack of generation investment in California, including more unpredictable regulatory review and a longer permit process, 4 months longer than Pennsylvania and 10 months longer than Texas. Also, the GAO reports that Clean Air Act standards complicate permitting in California, and the unstable California market may scare off energy development.

Republican Representative Doug Ose has lauded the report and finds it supports his efforts to eliminate governor Gray Davis' control of the California Independent System Operator. Ose also asserts that changes must be made or shortages will plague the state again soon, although many energy officials have already asserted that the state has sufficient supply, and new energy projects are under development.
