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.

California Supply Situation Could Deteriorate Quickly

LCG, Apr. 9, 2003--Testimony by the head of the California Independent System Operator (ISO) and others before a House Government Reform subcommittee Tuesday indicated that while California's power supply appears adequate for the approaching summer, uncertainty still looms, and could be exacerbated by better economic conditions.

Terry Winter said that if the economy does not accelerate quickly, supply might be sufficient to guard against shortages until 2006 and 2007. Nonethless, given the possibility that Silicon Valley's economy will pick up by next year, Winter said he had "considerable concerns." Another witness, George Fraser of the Northern California Power Agency, noted that changes proposed by the ISO to remake California's power market structure were advancing towards implementation slowly, and did not have provisions for encouraging new transmission investment.

Legislation was to be announced today by members of the state legislature, including Senate President Pro Tem John Burton, D-San Francisco, that would dismantle key features of AB 1890, and undo the state's "failed experiment with energy deregulation." Besides the risks posed by reluctance to invest in new generation and transmission, California's supply situation is affected by runoff for hydro. If dry conditions were to suppress power generation from that source, the subcommittee Chairman Doug Ose, R-Sacramento noted, "we could be getting into trouble in 2005, 2004 with bad weather."

The Federal Energy Regulatory Commission's chairman, Pat Wood III, said that not just wholesale but retail changes in regulations, and price-responsive conservation from businesses and consumers, would be needed while investment improves the excess of supply relative to demand.
