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.

Constellation Moves on 680 Megawatt Florida Plant

LCG, April 2, 2001A subsidiary of Constellation Energy Group Inc. said Friday it has begun site clearing for a 680 megawatt merchant power plant to be built in an industrial area close to the city of Cocoa, Fla.

The facility, called the Oleander Power Plant, will sell 80 percent of its output to the Seminole Electric Cooperative of Tampa under a seven-year arrangement which will begin late next year. The remainder of the plant's power will be sold into the Florida wholesale market.

"Building a peaking power plant to serve the Sunshine State is important because electric generation reserves in the state have declined in recent years," said Oleander project manager Richard L. Wolfinger. "The Oleander Plant will provide additional capacity to Seminole Electric Cooperative and, because it will increase electric generation reserves, it will also offer added electric reliability for Florida."

The city of Cocoa has agreed to supply enough reclaimed water to the Oleander Power Plant to meet at least 65 percent of the facility's water requirements.
