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.

Japanese Approve New 2,740 Megawatt Nuclear Plant

LCG, May 16, 2001A panel of the Japanese Economy, Trade and Industry Ministry this morning approved plans to build a large, new nuclear power plant near Hiroshima in southern Japan.

Nuclear development in Japan, which gets about a third of its electricity from nuclear plants, has been at a standstill since an accident at a fuel processing plant in Tokaimura killed two workers in 1999.

Koichi Sakamoto, a spokesman for the ministry, said the approval by the electric power panel is expected to be officially endorsed by the ministry next month. He added that Chugoku Electric Power Co., which will operate the plant, had worked with local governments and had obtained the backing of residents in Yamaguchi prefecture.

Chugoku plans to build two 1,370 megawatt reactors at the site in Kaminoseki, the first to be completed in 2012 and the second in 2015.
