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.

Reporting to Energy Price Index Publications Falls Off

LCG, Nov. 15, 2002--Traders at a number of large energy companies have begun not to provide any price data concerning their transactions to industry publications, and in some cases are releasing the information themselves through their risk oversight units.

The likely result of the change in reporting patterns is to make the price indexes less representative and reliable as a source of market information. William Hogan, a professor at Harvard University who serves as director of research for the Harvard Electricity Policy Group, told the Wall Street Journal, "The tradeoff here is between easy access to imperfect information and difficult access to better information. It's not completely obvious to me which one is beter and which is worse. There is a real danger here that everybody decides to clam up."

Regional differences in the numbers of deals taking place will affect some indexes more than others, where the published indexes are concerned. One of the most widely known set of indexes is published by Platts, a company owned by McGraw-Hill Cos. Both electricity and natural gas, for which trading volumes are greater, have experienced changes. Constellation Energy Group, El Paso, Reliant Resources Inc., PPL Corp., Williams and CMS are no longer reporting prices in any way.

While some companies have disclosed that false prices were submitted to index publishers by their traders and are now cooperating with federal authorities, others who may fear being subpoenaed appear to have decided it is less risky to simply not report should they make an error in reporting. "If you start losing the price transparency, it creates advantages for big companies and probably leads to higher prices," said Phili Verleger Jr., an economic consultant in Newport Beach, Calif.
