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 Gets Okay to Reopen Killer Gas Line

LCG, July 9, 2001El Paso Energy Corp. has been given permission to resume natural gas transmission on its pipeline which was shut down by an explosion last August killing 12 people camped alongside it near Carlsbad, N.M.

El Paso's South Mainline system consists of three trunklines that carry gas from West Texas to California. Together, they were carrying about 1.1 billion cubic feet of das per day at the time of the rupture. Following the blast, transmission was cut to 835 million cubic feet per day but has recently held steady at around 920 million cubic feet.

The Department of Transportation said on Friday that El Paso could begin operating the damaged line at 80 percent of capacity as it completes its final inspection of repairs. Patricia Klinger, a DOT spokeswoman, explained "The line needs to be running to conduct internal inspections."

"They are finished with the reconstruction, the hydro testing and internal cleaning. Just the internal inspection is required now," Klinger said. Federal inspectors will make the final determination whether the pipeline can run at full capacity, she added.

El Paso has begun switching the flow of gas from one of the others pipeline to the repaired line, but that will not for the time being increase the overall amount of gas heading to California, a company spokeswoman said. She said shippers would be notified when increased pressure allowed additional gas to be moved.

The federal agency fined El Paso $2.52 million last month for the fatal explosion, the largest fine ever against a gas pipeline operator.
