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.

Perry Nuke Completes Best-ever Refueling in 34 Days

LCG, March 26, 2001--First Energy Nuclear Operating Co. said Friday that operators at its Perry nuclear power plant had returned the facility to service that morning, completing the shortest refueling in the plant's 13-year history.

First Energy said the refueling was done in 34 days, shaving three days off the previous best of 37 days set in May 1999. The 1,320 megawatt reactor was operating at 29 percent of capacity this morning, according to the Nuclear Regulatory Commission's daily plant status report. First Energy said output would be gradually increased to 100 percent over the next week or so.

During the outage, major work included replacing 304, or about 40 percent, of the plant's 748 fuel assemblies. The new fuel assemblies are equivalent to more than 75,000 train carloads of coal, the company said. One of the turbine rotors also was modified, allowing for increased power output of 5 percent.

"Our employees met the challenge of safely completing an ambitious work schedule," said JohnWood, site vice president at Perry. "Our team did the right work at the right time to help ensure Perryremains a top performer in the areas of safety and operations."

During its last cycle of 655 days, Perry missed only 11 days' work, posting a 98.2 percent capacity factor.
