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.

Paper Company Sells Maine Hydropower Assets

LCG, Oct. 12, 2001--Canadian real estate, power generating, natural resource and financial firm Brascan Corp. announced this morning an agreement to purchase from Great Northern Paper Inc. a hydroelectric generating and transmission system in northern Maine for $156.5 million.

Brascan said the acquisition by its subsidiary, Great Lakes Power Inc., will increase Brascan's total power generating capacity to over 1,100 megawatts and enhance its ability to market power in the increasingly integrated North American energy markets.

Brascan said it will acquire 280 megawatts of combined generating capacity, consisting of six hydroelectric generating stations with 130 megawatts among them and Great Northern's thermal generating plant of 150 megawatts.

According to Brascan, the acquisition includes several generation and transmission assets.

  • Six hydroelectric generating stations located on the Penobscot River with a combined capacity of about 130 megawatts.

  • Eleven dams, the impoundments of which are capable of storing water sufficient to generate 300,000 megawatt-hours of electric power.

  • Opportunities through capital investment to enhance the system's output and improve the reliability and efficiency of its generating units.

  • Marketing agreements for up to 15 years with Great Northern for the supply of energy and the sale of surplus power production from the generating stations.

Brascan and Great Northern have also agreed to jointly study the development of a new transmission line connecting Quebec with the New England Power Pool, using Great Northern's rights of way in northern Maine which extend to the Quebec border.
