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.

Bankruptcy Court Apprvoes PG&E Transmission Upgrades

LCG, Feb. 12, 2002--Requests made by Pacific Gas and Electric last month for approval of two major transmission projects have been answered in the affirmative by the U.S. Bankruptcy Court.

Due to PG&E's bankrupt status, spending items of over $50 million must be reviewed by the court. The Path 15 upgrade's financing is being overseen by public and private entities, many of which will co-own the lines. PG&E has been allowed to spend up to $75 million for the upgrades, which will join lines connected to the Los Banos and Gates substations.

The other item approved, the Tri-Valley Capacity Upgrade project, will lead to improvements of the California transmission system east of San Francisco. The system is nearing capacity, and serves Dublin, Livermore, Pleasanton and San Ramon, among other communities. These municipalities have granted their own approvals, as has the Official Creditors' Committee. The project will receive as much as $136.9 milion.

The Path 15 upgrade in particular was seen last year as a means of preventing future supply crises in California due to transmission bottlenecks.
