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 Reaffirms Approval of Kern River Gas Projects

LCG, Oct. 25, 2001--The Federal Energy Regulatory Commission yesterday reaffirmed its approval of two projects by a unit of The Williams Cos. aimed at increasing capacity on a natural gas pipeline into California.

Objections to the Kern River Gas Transmission Co. projects had been raised by companies that are presently shippers on the line. They complained that expanding capacity for new customers would reduce space available for their gas and asked FERC to reconsider the project approval.

Noting that there is a "critical need" for more pipeline capacity to serve California's growing fleet of gas-fueled power plants, FERC said the benefits of the projects outweighed any potential adverse impact on existing customers.

The two projects, called "The California Action Project" and the "2002 Expansion Project" will provide almost 150 million cubic feet of gas per day from Wyoming to California, and are scheduled for completion next May. The Kern River pipeline stretches 922 miles from gas fields in Wyoming to California.

Separately, Fern River has asked FERC for approval of plans to add 900 million cubic feet of daily capacity to the line in a project that would more than double current capacity and cost around $1 billion.
