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.

El Paso to Check Killer Gas Line This Week

LCG, March 20, 2001El Paso Natural Gas Co. said yesterday that it would conduct a two-day inspection tomorrow and Thursday of the natural gas pipeline that exploded last August near Carlsbad, N.M., killing 12 persons who were camped near the line.

The inspection has been twice delayed as El Paso removed debris left by repair. "We will complete the line cleaning today and begin the inspection on South Mainline on March 21 and 22," a spokeswoman for El Paso Energy Corp. said yesterday.

The South Mainline, which connects a Texas gas basin to California, was repaired following the blast, but has been operating below capacity because of federal restrictions, cutting gas flows to the west by 200 million cubic feet per day. This week's test should be one of the last hurdles before the line can be restored to its full 1.1 billion cubic feet per day capacity.

The El Paso spokeswoman said the inspection process will reduce flows by another 335 million cubic feet per day. Following the test, results will be submitted to the U.S. Office of Pipeline Safety, a division of the Department of Transportation, which will determine whether the South Mainline is safe for regular service.
