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 Receives Criticism Over Grid Incentives

LCG, Mar. 14, 2003--The period allowed by Federal Energy Regulatory Commission (FERC) for public comment on current rulemaking proposals ended yesterday, with a number of commercial energy users and state agencies questioning a method to reward utilities that sell their transmission assets or make them part of regional grids.

Numerous estimates were made of how much energy consumers would pay to utilities that were allowed incentives of up to 300 basis points in higher rates of return to yield control of their transmission assets. FERC believes that opening the transmission grid by encouraging regional transmission organizations would lead to lower energy prices. While the Edison Electric Institute, a representative for a group of large investor-owned utilities, put the cost of the incentives at $20 million per year, a group of state consumer advocates estimated their cost at $711 million per year.

Profit margins of 15 percent could be possible for utilities under the proposed rules. Williams Cos. Inc. found that the reduction of discrimination in grid access would be beneficial, with the incentives costing residential consumers less than $2 per year. Companies submitting comments to the FERC included Boeing Co., Georgia-Pacific Corp., Hewlett-Packard Co. and Weyerhauser Co. Members of that group found the rates of return that would be allowed to be excessive.
