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.

RTO for U.S. Northeast 'Do-able', PJM Chief Says

LCG, July 25, 2001The chairman of the PJM Interconnection said yesterday that the independent system operators in the U.S. Northeast were on track to combining their operations into a regional transmission organization.

The Federal Energy Regulatory Commission on July 11 ordered the New York Independent System Operator, PJM, PJM West, Northeast ISO and New England ISO to form a single RTO.

"I think that's do-able," Phillip Harris told reporters at a briefing covering a closed door hearing held Monday before FERC Administrative Law Judge Peter Young. Officials of all four ISOs met to begin 45 days of negotiations aimed at forming a single Northwest RTO.

"We can't solve all of the issues, but we can come up with a plan" during that time, Harris said.

Separately, PPL Corp., which has operations in PJM, Northeast ISO and New York ISO areas, said it supports a Northeast ISO as a "significant step toward establishing a reliable and properly functioning wholesale electricity market."

FERC has said the PJM system which serves Pennsylvania, New Jersey and Maryland could serve as a model for regional organizations nationwide, but the agency has turned down requests by to New York and Northeast ISOs to retain their status as separate independent system operators.

PPL tempered its enthusiasm for PJM, saying the organization has "significant problems with its markets and structures that must be resolved" before it could absorb the other ISOs.

Earlier this year, FERC proposed that there be four regional RTOs covering the U.S., but Harris said their could be as many as 10. He also endorsed the PJM model, saying "The technology is there to make it happen," adding "it's hard to find something bigger than what we're doing."
