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 Proposes Standard Market Framework

LCG, March 13, 2002--The Federal Energy Regulatory Commission (FERC) presented an outline for nationally standardizing the U.S. energy market.

The Commission will provide a paper on standard market design involving the development of open-access transmission tariff which would fall under the administration of regional transmission organizers (RTO). RTO's will be responsible for preventing generators from influencing prices by withholding power.

After the Supreme Court Decision last week validating FERC's authority over wholesale transmission sales, the commission is in a position to dictate rules for the competitive market, taking control from the hands of state regulators.

FERC plans to instate a method for electricity pricing called Location Marginal Pricing (LMP), an approach used by mid-Atlantic PJM Interconnection LLC which allows those in the market to circumvent price risk from congestion.
