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.

Close Delayed on Two NRG Energy Plant Acquisitions

LCG, July 26, 2001-- NRG Energy Inc. said this morning that the Federal Energy Regulatory Commission has instructed its staff to convene a technical conference to "further explore issues related to the competitive effects" resulting from NRG's proposed acquisition of the Bridgeport and New Haven Harbor Stations in Connecticut.

The order directs FERC staff to report back to the Commission within 90 days after exploring "issues regarding market power concerns."

NRG has planned extensive emissions upgrades to the 660 megawatt Bridgeport plant and the 460 megawatt New Haven station, both of which it is buying from United Illuminating Co. FERC's action will delay closing the transaction beyond this summer, the original target of the companies, NRG said.

"Upon review of the FERC order received yesterday, it is clear some issues have yet to be resolved. However, NRG is confident the FERC will ultimately approve the transaction," said Craig A. Mataczynski, chief executive of NRG North America.

"Connecticut will benefit from this acquisition as it will help to ensure a healthy fuel diversity within New England's power grid so that affordable, reliable and environmentally responsible electricity is available when and where it is needed," he added.

Mataczynski said his company plans significant cuts in emission from both plants. , "NRG remains committed to reducing sulphur emissions at the New Haven facility by 50 percent and, after installing additional environmental controls, reducing sulphur emissions by more than 90 percent at the Bridgeport Harbor facility," he said.

The transaction also requires approval by the U.S. Department of Justice.
