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.

FPL Files to Build New Nuclear Reactors

LCG, October 18, 2007--Florida Power & Light Company (FPL) Tuesday filed plans to construct two nuclear reactors at its Turkey Point Generating Station with the Florida Public Service Commission (PSC). The project would add approximately 2,200 to 3,000 MW of new, base-load electric generating capacity to meet the growing demand for power of FPL's customers by the year 2020.

The filing, which requests a determination of need, was the initial step toward receiving approval from the state to build the new reactors. The new reactors, which have no carbon emissions, would be consistent with Florida Governor Crist?s objective to reduce global greenhouse gas (GHG) emissions.

In August, FPL announce plans to add the two nuclear reactors at a Florida PSC workshop on future energy needs. In addition, FPL stated that it plans to increase electric generating capacity at the existing St. Lucie nuclear power plant and at Turkey Point by a total of 400 MW. The increase is scheduled by 2012, given timely regulatory approvals.

FPL noted that, prior to its making a final decision to pursuethe construction of the two new reactors, it will be involved in wide-ranging discussions and consultations with local residents and governments and must obtain approvals from several state and federal agencies, including the federal government?s Nuclear Regulatory Commission (NRC). FPL also noted that, together with the PSC, it will evaluate the cost-effectiveness of the project at every stage.

FPL is not alone in planning new nuclear reactors in Florida. In December of 2006, Progress Energy Florida selected a site in Levy County, Florida about eight miles north of its existing Crystal River Energy Complex for the possible construction of a new nuclear power plant. Furthermore, Progress Energy Florida in July announced that Westinghouse Electric Co.'s AP1000 was selected for nuclear reactor additions in Florida. The company has stated that it plans to file a need case with the Florida PSC in early 2008. Assuming the decision is to proceed, construction could begin in 2012, with commercial operation scheduled for 2016, according to Progress.
