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.

Payer of Connecticut Utility's Congestion Charges Disputed

LCG, July 2, 2003--Charges for congestion that have been included in Connecticut Light & Power (CL&P) ratepayers' bills will continue to be the responsibility of the utility, not suppliers, unless the Federal Energy Regulatory Commission rules otherwise.

The charges, which arise when the effective limit of transmission lines' capacity is reached, were first put in place in March by the Independent System Operator - New England (ISO-NE). So far, the costs have amounted to $47 million, and represent about 6 percent on the typical customer's bill. As congestion costs change according to disparities in generation costs between different areas, they are intended to encourage investment, which would serve to drive the costs down.

The Connecticut Department of Public Utility Control (DPUC) determined that the congestion charges should be paid by CL&P at present. The utility contended that suppliers such as Northeast Utilities' Select Energy, Xcel Energy Inc.'s NRG Energy, and Duke Energy Corp. should pay the costs. FERC intends to determine a timetable for deciding the issue on July 9.
