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.

Talks Between EPA and NJ Utility End in Settlement

LCG, Jan. 25, 2002--Following more than a year of talks between Public Service Enterprise Group Fossil LLC and the Environmental Protection Agency, the New Jersey utility will pay $1.4 million in fines and make improvements at two power plants worth $340 million.

The EPA found that the power plants, in Jersey City and Hamilton, were subject to mid-1990's rules covering coal-fired plants. The agency administrator, Christie Todd Whitman, said the result is "an excellent example of how effective federal and state partnerships in enforcement actions can greatly benefit the environment and assure public health protection."

Following the Bush administration's call in the spring of 2001 for a review of EPA enforcement of the Clean Air Act, lawsuits filed under the Clinton administration were temporarily halted. A week ago, the Justice Department announced that the suits against owners of 51 coal-burning power plants would go forward.

The settlement, which will need to be approved by a federal judge, would mean that PSEG Fossil will cut emissions of sulfur dioxide from the plants by 36,000 tons annualy. Nitrogen dioxide emissions would be cut by 18,000 tons.

Frank Cassidy, PSEG Fossil's president, stated, "coal has been, and will continue to be, the backbone of affordable energy in this country. But technologies exist to burn coal cleanly."
