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.

Midwest Gen, Union Meet in Strike Talks

LCG, July 17, 2001Official of the International Brotherhood of Electrical Workers and negotiators from Midwest Generation LLC, operator of 12 coal-fired power plants in Illinois, will meet with a federal mediator Thursday, the first indication of a thawing in the three-week old standoff.

IBEW workers walked out at the 12 plants, which account for a quarter of all the electricity generated in Illinois, on June 28 after rejecting a pay raise offered by Midwest Gen. The company countered that the union had demanded work rules changes that would have usurped its ability to effectively manage the plants.

A Midwest Gen spokesman confirmed the talks with the mediator, adding that the company welcomed the opportunity to sit down with the union to resolve their differences. The IBEW has said the company has refused to bargain in good faith. Its members have worked without a contract since April 1.

The 12 plants, seven baseload stations and five peaking plants, were purchased from Commonwealth Edison Co., and ComEd buys their output. Together, they have a capacity of about 9,300 megawatts.

Midwest Generation is owned by Edison Mission Energy, a subsidiary of Los Angeles-based Edison International Inc.
