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.

Exelon Announces Plan to Install 195 MW of Additional Peaking Capacity in Medway, Massachusetts

LCG, February 6, 2015--Exelon Generation announced yesterday that it will add two gas-fired peaking units at an existing power plant in Medway, Massachusetts. The expansion project is in the permitting phase now, and construction is expected to begin in 2017. The project is scheduled to be completed by the summer of 2018.

The project will add 195 MW of capacity to the existing West Medway Generating Station, which was acquired by Exelon from Boston Edison in 2002. The existing plant capacity is 117 MW and includes three peaking units that can be fueled by either natural gas or oil. The two new units will also have dual fuel capability.

The new peaking capacity is planned to improve regional reliability and complement the growing intermittent solar and wind resources.

The president of Exelon Power stated, "We are excited to develop this new project in the greater Boston area.This project demonstrates the new 'pay for performance' capacity construct works and that it will attract development of new resources needed in the region."
