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.

Florida Power 530 Megawatt Plant Approved

LCG, Dec. 22, 2000--Florida Power Corp. said yesterday the Florida Public Service Commission has unanimously approved its request for permission to build a second 530 megawatt natural gas-fueled, combined-cycle power plant at the company's Hines Energy Complex in Polk County, east of Tampa.

The company said the new unit, scheduled to be in service by the end of 2003, will be a sister to the already operating Hines Unit 1 which began operations last year. The new Hines Unit 2 will be built by Siemens-Westinghouse, Florida Power said.

"Building Hines 2 is just one of the many ways Florida Power will meet its commitment to customersto provide competitively priced, reliable energy as the region continues to grow," said Florida PowerPresident William Habermeyer. "This new power plant ensures that we will be able to meet the growing energy needs of our customers."

There remains a regulatory hurdle for the new plant which requires Supplemental Site Certification from the Florida Department of Environmental Protection. The company filed for the certificate this last July and expects approval before next summer.

In California, that would take two or three years.
