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.

Reliant Takes Over Duke's Florida Power Project

LCG, June 12, 2001Reliant Resources Inc., a subsidiary of Houston-based Reliant Energy Inc., said yesterday it had taken over from Duke Energy Corp. the development of a 500 megawatt power plant in New Smyrna Beach, Fla.

In August 1998, Duke announced that it would build the merchant plant in conjunction with the Utilities Commission of New Smyrna Beach, conforming to Florida law which bans non-utility power plants unless built in partnership with municipal utilities. In March 1999, the Florida Public Service Commission gave Duke permission to build the plant.

But Florida's investor-owned utilities didn't want an out-of-state company building power plants on their turf, and brought suit to block the plant in the state's highly parochial Supreme Court. In April 2000, the Florida high court sided with the utilities, banning the project on a 6-1 vote.

Duke recently terminated its agreement with the New Smyrna Beach municipal utility, and Reliant has stepped in to take on the project.

"Florida is a key market for us, and the New Smyrna Beach Power Project represents another step in our strategy to meet demand for electricity in one of the fastest-growing areas of the country," saidCurtis Morgan, president of Reliant Resources Eastern Region.

"We are excited about the prospects of working with the City of New Smyrna Beach and other Florida load-serving entities on this project," he added. "We believe that this additional base-load capacity will be well received by the local wholesale market."
