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.

Siting of New York City Plant Not Finalized

LCG, Aug. 26, 2003--A power plant that could provide both steam and electricity to New York City and which developer TransGas hopes to build in Greenpoint, Brooklyn, would be better located in an industrial area, according to Michael Bloomberg and some neighborhood groups.

According to a lawyer for TransGas, Sam Laniado, it did not have communications from the city about alternative locations. A spokesman for Mayor Bloomberg, Jordan Barowitz, agrees that New York City needs to address both transmission and generation deficiencies to avert future blackouts. Other blackouts took place in the city in 1999 and 2002.

Bloomberg said that although a power plant has to be built, opposition to siting in residential areas is essentially universal. The city is hoping to have development of the Greenpoint area that would replace old docks and warehouses with housing. Greenpoint, which stretches for about one-and-a-half miles, offers excellent views of the Manhattan skyline, as well as superb transmission access, according to TransGas. Laniado noted that the city would not have final authority in the siting of the plant it plans to build.
