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.

Ozone Requirement to Be Enforced

LCG, November 18, 2002-The EPA and environmental groups have come to an agreement over enforcement of air pollution standards.

In 1997 the Environmental Protection Agency adopted a program to limit ozone, an unhealthy chemical created and used in several industry processes.

The compound, O3, is important in its function farther out from the earth's surface in the ozone layer but is unsafe closer to the earth's surface where it quickly reacts with chemicals in humans and other organisms, and can damage DNA. Most commonly, the unstable chemical causes respiratory problems in humans.

Several environmental groups, including Environmental Defense, Southern Alliance for Clean Energy, and the Sierra Club, worked together to file suit against the EPA to insist that the organization enforce its 1997 rules limiting ozone in the air.

The maximum allowed ozone level is 0.08 parts per million, but the EPA never took measurements because industries complained the regulation was too strict. Ozone can be detected by the human nose at a level between 0.02 and 0.05 ppm.

The EPA has agreed to determine whether or not areas pass the requirement and to take steps to reduce ozone levels in these areas, although such steps are as yet unspecified.

Some groups estimate as many as 38 states have areas with unacceptably high ozone levels.

The American Lung Association approximates that half the US population lives in areas where air pollution is high enough to cause serious respiratory ailments, as well as other health problems.
