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.

PG&E Unit Owes Rhode Island Utility for Power

LCG, July 6, 2001The Providence (R.I.) Journal wondered this morning how it was possible for a big electric power plant owned by a big utility holding company headquartered in a huge state to owe an itty-bitty local utility in the nation's smallest state more than a half-billion dollars for electricity.

The Manchester Street Station can produce enough electricity to light more than half the homes in Rhode island, yet it is in arrears on $525,000 worth of electric bills to Narragansett Electric Co., the local utility for Providence and environs and former owner of the power plant.

The new owner is USGen New England, which the paper notes is owned by PG&E National Energy Group, which is owned in turn by PG&E Corp. and is a sister company of Pacific Gas & Electric Co., which is the local utility for San Francisco and two-thirds of California.

"PG&E National Energy Group is flush with cash (and) can afford to pay its bill)" the Journal thought.

What is a 495 megawatt power plant doing buying electricity in the first place? Well, it can't run all the time, but its customers expect electricity all the time, so USGen buys power from others when it is fixing the Manchester Street Station.

Narragansett Electric says it has been sending a monthly bill to USGen, but none of the bills have been paid. "They have decided to completely blow off their electric bill since September 1998," said Ronald Gerwatowski, the lawyer for the Providence utility.

A spokeswoman for USGen told the paper that details on the purchase of electricity from Narragansett Electric were spelled out at the time USGen bought the plant, but she didn't say whether those details covered non-payment of the bill.

The Journal said the issue has gone to the Rhode Island Public Utilities Commission for resolution.
