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.

FERC Judge Finds El Paso Withheld Natural Gas

LCG, Sep. 23, 2002--During the period Nov. 1, 2000, to Mar. 31, 2001, El Paso Natural Gas failed to release gas supplies to California that could have been used to provide electric power, a Federal Energy Regulatory Commission judge ruled today.

The ruling by Chief Judge Curtis Wagner stated that "El Paso Pipeline withheld extremely large amounts of capacity that it could have flowed to its California delivery points and in violation of its 10-year settlement agreement, which substantially tightened the supply of natural gas at the California border significantly, broadening the basis differential."

The company's chairman, William Wise, said in a statement, "We are disappointed that today's proposed decision does not recognize the substantial record evidence supporting El Paso Natural Gas' position that the pipeline was operated properly."

The ruling reflected a change in Wagner's assessment of El Paso's role in the power market. Last fall, the judge did not find evidence that El Paso had manipulated the market. Today's ruling was based on his conclusion that extra supplies of natural gas had been available to El Paso at the time.
