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.

Six Firms Qualify for Brazil's Cesp Auction

LCG, May 11, 2001The energy secretariat of Sao Paulo state in Brazil said yesterday that a Brazilian utility and five foreign firms have qualified for the May 16 auction of Cesp Parana, which provides about half of the electric power consumed in Brazil's most populous state.

Attempts to auction Cesp fizzled last year when all bidders withdrew at the last minute, citing risks in the utility's debt portfolio and its inability to fill the reservoir behind one of its largest hydroelectric facilities. Most of the companies problems have been resolved, observers say.

Base price for next Wednesday's auction has been set at 1.74 billion reals ($765 million U.S.), the same price in reals as last year's attempt. The price is lower in U.S. dollars, however, because of sharp declines in the Brazilian currency against that of the U.S.

A spokeswoman for Sao Paulo state said Duke Energy Corp., AES Corp. and NRG Energy Inc. of the U.S.; Electricit de France, and Electricidade de Portugal qualified to bid for Cesp. Minas Gerais state utility Cemig, which was restricted from bidding for a controlling stake in Cesp, was authorized to participate provided that it forms a bidding consortium with another firm.
