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.

FERC Conference Exposes Transmission Cost Conflict

LCG, November 7, 2002-In a Wednesday meeting, utilities and energy companies disagreed over the method by which transmission upgrades should be funded.

The Federal Energy Regulatory Commission held a day-long conference on some energy issues yesterday, including repairing the nation's transmission bottlenecks.

A FERC study released last year estimated that $12.6 billion would be needed to streamline transmission by constructing new transmission lines.

Energy companies who own plants and sell power assert that new transmission benefits retail customers and should therefore be paid by ratepayers in general via "rolled-in pricing."

Large investor-owned utilities oppose this idea, saying that ratepayers will be forced to pay for energy assets that do not benefit them. Utilities and some utility commissions insist that those who directly benefit from new projects coming on line should pay, whether state consumers, industrial users, or energy firms.

Calpine Corporation also took the opportunity to voice its concerns over unfair practices in transmission control, alleging that some utilities prevented electricity to be sold from its plants even though Calpine's power was cheaper and cleaner.
