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 to Conduct a New Standard Market Study

LCG, January 14, 2003The Federal Energy Regulatory Commission has agreed to take a second look at the implications of a standardized energy market, after some states voiced their concern over FERCs plans to create a set of rules for wholesale energy markets.

FERC suggested a new framework regarding the countrys electricity market last July, but some states have been worried over the transfer of authority from states to the federal government. Some members of the Congress have asserted that FERC plans to take power from state public utility agencies.

Energy officials from some 15 states have publicly voiced apprehension over FERCs plans, noting that consumers in Southern and Western states may have to pay more for power if the electricity market follows the proposed rules. Some industrial companies, who purchase and consume large amounts of electricity, worry that they will have to pay an unfair proportion of charges for transmission improvements.

The state of Louisiana requested that FERC scrap its market plans, while some industry groups have asked for looser guidelines.

Due to increased pressure, FERC has agreed to reassess its 2004 market design plans and delay the implementation of them. The main body of the plans addresses transmission issues, endeavoring to smooth out the energy market between states. The plans also include real-time trading and some measures to prevent gaming.
