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 Asked to Ease Caps on Northwest Power Prices

LCG, Aug. 31, 2001--A power planning group formed by the governors of four states in the Pacific Northwest has asked the Federal Energy Regulatory Commission to relax their price caps on electricity because of concern that the controls could restrict power supplies this winter.

The Northwest Power Planning Council says FERC's pricing formula, imposed in June on 11 states in the West, is based solely on the cost of producing power in California, which has little relevance for Washington, Oregon, Idaho and Montana.

In California, peak demand occurs during the summer when air conditioners are fighting a hot climate and drops during the clement winters. The situation is just the opposite in the Northwest, where many homes are heated by electricity and the winters are cold.

The council fears that FERC's pricing formula could keep prices artificially low in the Northwest and deter power producers from selling electricity into the regional market, just when it's needed most.

The council recommended several changes to FERC's rule, including one that would base power prices on the cost of production, and voted 6-2 to file the petition with FERC.

Another of the recommendations would require power producers in California to sell electricity into the four Northwestern states -- the reverse of Clinton administration rulings when the Department of Energy ordered Northwestern power producers to sell power to California during that state's energy emergencies last fall.

Those sales resulted in power shortages in the Northwest and higher prices for consumers in the four states.
