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.

TXU Mothballs Generation in UK Portfolio

LCG, Jan. 14, 2002--Citing falling wholesale prices and overcapacity in the UK power market, TXU will mothball part of two generating plants first commissioned over thirty years ago.

Wholesale power prices in the UK have dropped roughly 25 percent with the institution of the New Electricity Trading Arrangements (NETA) in March 2001. The NETA represents a more competitive market structure than the former England and Wales Electricity Pool of old. This, plus "specific issues of age, efficiency, reliability and maintenance requirements" were mentioned by Martin Stanley, TXU's president of trading and production, by way of explanation.

TXU, which negotiated the sale of the 2,000-megawatt West Burton power plant to Electricite de France for 366 million pounds ($530 million) two months ago, left open the possibility that generators at the Drakelow C and High Marnham plants could be brought back into service if the market warrants the move. The effect of mothballing the two plants will be to withdraw 522 megawatts from the UK market, which leaves more than 99 percent of the former capacity total intact.

Reuters reported that Paul Taylor, vice president of UK power trading did not foresee any additional generators being mothballed.
