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.

Wisconsin Sets Route for New Transmission Line

LCG, Oct. 25, 2001--The Public Service Commission of Wisconsin said yesterday it has issued the details and route specifics of the 220-mile electric transmission line from Wausau to Duluth. The PSCW had approved the line on August 17.

The new transmission line, backed both by Wisconsin utilities and state officials as necessary to relieve annual summer power shortages by making it possible to import electricity from states to the west and from Canada, had been opposed by "not in my backyard" interests.

The commission, in its order, managed to squeeze about 83 percent of the new line into existing rights-of-way, minimizing the impact on landowners in northern Wisconsin.

The new transmission line is a joint venture between Wisconsin Public Service Corp. and Minnesota Power Co. With the PSCW's written final order, the utilities will proceed with the project and begin the engineering and geographical surveys that need to be completed before 2002 when construction is expected to begin which is expected to take about three years.

"We are pleased the final order has been issued," said Don Shippar, chief operating officer of Minnesota Power. "We hope this project can be an example to show how communities, utilities and private landowners in Wisconsin and Minnesota can work together to solve the electric reliability problem in this region."

Patrick Schrickel, president and chief operating officer of Wisconsin Public Service, attempted to put landowners at ease. "We intend to work fairly with any private and public land owners who may require easements on their property," he said. "It's a negotiated process which is guided by state law."
