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 Files Suit Against CA ISO for Noncompliance

LCG, August 19, 2002-The Federal Energy Regulatory Commission has filed a lawsuit against the California Independent System Operator because the ISO did not comply with a FERC order to change its governing board.

FERC ordered the California ISO to disband and restructure itself into a two-tiered board. The board was to be divided into independent and advisory boards, the latter containing industry members such as consumer advocates, utility officials, and plant owners. FERC asserts that the ISO board is not independent enough.

Earlier this month, the ISO's board, which was appointed by Governor Gray Davis, voted to ignore FERC's order, and nine days later FERC brought a lawsuit against the organization.

The deadline for compliance was Thursday; Friday, FERC filed the suit in a Washington federal court.

Governor Davis and State Attorney General Bill Lockyer are among those most vocally opposed to FERC's attempt to regulate the organization responsible for California's electricity transmission reliability.

Some have pointed out that FERC members were appointed in a similar way by President Bush.
