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.

House Bill May Overrule Local Authorities in Favor of Transmission Construction

LCG, September 16, 2003Republicans from Western and Eastern states may face complicated negotiations over a proposed bill to give the federal government greater power in constructing electricity transmission.

The U.S. House of Representatives bill in question would give the Federal Energy Regulatory Commission power to approve electricity transmission routes even if state or local authorities have refused such routes. Companies involved in constructing transmission would be allowed to construct lines so long as they pay land-owners.

Some Republicans wholeheartedly support the bill, which gives greater powers to the federal government and the energy industry. Many Republicans oppose the bill, valuing the right to property and privacy over federal powers.

Electricity transmission construction has always lead to discord among landowners, government, and energy companies. Disagreement often is based upon environmental, health, and safety concerns, as well as property value and economic concerns.

Many of those opposed to the bill say it is based upon a faulty premise, that landowners pose a significant barrier to transmission construction. They say that opposition is rare and, when it occurs, manageable.

The Bush Administration strongly supports the bill. The Senate energy bill does not yet have a parallel provision. Republican legislators will encounter some controversy amongst themselves when discussing the bill, especially as Western and Eastern representatives are likely to have very different perspectives.
