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.

European Power Outage Affects Nearly 4 Million

LCG, Sept. 26, 2003--Early Tuesday evening, southern Sweden and eastern Denmark experienced a blackout that was apparently caused by a failure on a transmission line, and which lasted several hours.

Denmark's capital city of Copenhagen as well as an industrialized area of Sweden were affected by the outage, which was estimated to have affected almost four million people across the two countries. The line that failed crosses the border between Sweden and Denmark.

The economic impact of the blackout was thought to be "very modest", according to an economist with Dankse Bank, Jesper Hansen, who was quoted in Dow Jones Newswires. While some pharmaceutical factories and other industrial facilities were forced to shut down, and nearly all businesses in Copenhagen closed, financial markets remained open, thanks to backup generators. Traffic congestion resulted on roadways, and airlines and rail traffic were temporarily disrupted until power was restored, first in Sweden and next in the islands of Denmark that had been impacted.
