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.

Exploding Manholes Disrupt Part of Nation's Capital

LCG, June 14, 2001Morning shoppers in the fashionable Georgetown section of Washington, D.C., were dismayed today, but not surprised, to see at least a half-dozen manholes on M Street, the main street of the upscale area, spewing fire and smoke.

They were not surprised because the same thing happened yesterday and three times in May. In contrast to last month's manhole explosions, the cast iron manhole covers did not fly into the air, but that's not because of decreasing violence within the subterranean chambers.

The old manhole covers were replaced with a new, cutting edge model that is slotted to allow exploding pressures to escape to the atmosphere. The manholes and their contents are owned by Potomac Electric Power Co., or Pepco as the utility is called locally.

At 8:30 PDT today, almost noon in Washington, M Street was closed from Wisconsin Avenue to 28th Street to allow Pepco crews to inspect the cables within the manholes and make needed repairs. The street, a major commute route in and out of the federal district, will be closed throughout this evening's rush hour.

Yesterday, in mid-afternoon, the latest problems became evident when fire and smoke shot from the manholes. Stores and restaurants were evacuated and about 1,500 commercial customers were without power until late in the evening. The same customers are affected by today's problems.

"It's just one disaster after another," Dan Crockett, president of a Georgetown consumers group, told the Washington Post. "It's a frustration for the residents and it's a frustration for the businesses here."

Peter LaPorte, head of the District of Columbia Emergency Management Agency, said "We're all sick and tired of this."

Pepco spokesman Bob Dobkin said "We're trying to do a damage assessment."
