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.

NRC Approves License Transfers in Unicom-Peco Merger

LCG, Aug. 7, 2000--The Nuclear Regulatory Commission said Friday it has approved the transfer of operating licenses for 20 commercial nuclear reactors from Commonwealth Edison Co. and Peco Energy Co. to Exelon Generation Co.

Exelon Generation will be a subsidiary of the new holding company formed by the pending merger between ComEd and Peco.

Affected by the approval are 13 ComEd reactors, including two at the permanently-shuttered Zion plant and the Dresden Unit 1 reactor, which is also permanently shut down. Five Peco reactors are affected, including Peach Bottom Unit 1, which is permanently shut down.

Salem Units 1 and 2 were also affected by the approval because Peco has an ownership interest in them, though they are operated by Public Service Electric & Gas Co.

The NRC said notices of the requests for approval and for an opportunity for a hearing were published in the Federal Register on March 9. The Commission received no comments or hearing requests. The technical staff's approval becomes effective immediately.
