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.

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.

Duane Arnold Nuke Near Restart After Electric Fix
LCG, Oct. 23, 2001--A spokeswoman for the company that manages operation of Alliant Energy Corp.'s 535 megawatt Duane Arnold nuclear power plant near Cedar Rapids, Iowa, said the plant was preparing for a restart after repairs made to a faulty electric system.Maureen Brown, a spokeswoman for Nuclear Management Co., the plant's operator, said the maintenance work had been completed and the reactor was in "hot standby" yesterday morning. The continued shutdown of the Nuclear Regulatory Commission Website, and its daily plant status report, makes it difficult to know whether the plant has been restarted.Brown declined to guess at when the plant would be back in service, though yesterday's hot standby could mean today's restart. According to the Nuclear management Co. Website, Duane Arnold was at 7.8 percent power this morning. It will take several days to ramp the reactor up to full power.The plant was shut down manually on October 17 when operators noticed a fault in the electric system that controls cooling water circulation. Workers took advantage of the shutdown to replace a pump seal that had been scheduled for repairs later this month. Alliant Energy's IES Utilities Inc. owns 70 percent of Duane Arnold. Central Iowa Power Cooperative, with 20 percent, and Corn Belt Power Cooperative, with 10 percent, are the other owners.
