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.

Northeastern, Mid-Atlantic States to Begin Talks on Plant Emissions

LCG, July 25, 2003--Discussion on a possible cap-and-trade program for power plant emissions will begin between the states of New York, Connecticut, New Jersey, Vermont, New Hampshire, Delaware, Maine, Pennsylvania, Massachusetts, and Rhode Island, with an agreement envisioned by April 2005.

The talks were proposed by Gov. George Pataki, of New York. The responses from the states have varied, with some, such as New Jersey, looking at restricting multiple pollutants, rather than creating a market for credits for carbon dioxide alone, which is what is addressed by Pataki's proposal.

The director of the air and energy program of the Natural Resources Defense Council, Ashok Gupta, told the New York Times that the conservation organization is "hopeful that this will be the precursor to a national cap-and-trade program for carbon dioxide." Thus far, the Bush administration has not given support to a cap-and-trade proposal by Senators Joseph Lieberman, D-Conn., and John McCain, R-Ariz., but has asked industry to consider voluntary reductions of their emissions, in the belief that outright limits would cause economic harm. It has also asked for more research into the science of global warming. Aides to Gov. Pataki, a Republican, have said that the talks do not represent conflict with the administration's climate policy.
