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.

Terrorist Threat Could Scuttle Maryland LNG Plant

The Federal Energy Regulatory Commission on Friday met with state and local officials to discussnational security concerns connected with restarting a liquefied natural gas plant near the Calvert Cliffs nuclear power plant in southern Maryland.

Last month, FERC gave permission to The Williams Cos. to reopen and expand the company's Cove Point liquefied natural gas plant despite concerns that the facility could be subject to sabotage that would threaten a nearby nuclear plant owned by Baltimore utility Constellation Energy Group.

Massachusetts officials shut down an LNG terminal in Boston following the September 11 attacks on the World Trade Center and the Pentagon. Officials feared an LNG tanker entering Boston harbor could be subject to sabotage, causing massive damage.

Democrat Sen. Barbara Mikulski of Maryland had demanded that FERC reconsider its approval order from last month. "You must carefully consider the fact that the Cove Point facility is within 3.5 miles of the Calvert Cliffs nuclear power plant and the ships that carry liquefied natural gas from Algeria or other countries will be under foreign flag with foreign crews," Mikulski said in a letter to FERC.
