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.

Hydro One Plans to Build New Electric Transmission Interconnection

LCG, March 28, 2007--Hydro One earlier this week announced plans to pursue the necessary approvals to enable the construction of a 500 kv electric transmission line along an existing transmission path. The new transmission facilities will provide markets in Ontario greater access to both wind power and nuclear power generated at the Bruce Power Station. The new transmission line is scheduled to be in service by December 2011.

The Ontario Power Authority (OPA) earlier this week announced the route that it recommends. The new line would extend nearly 110 miles from the Bruce Power facility to Hydro One's Milton switching station located in the Town of Milton.

Last fall the OPA issued a report outlining how alleviation of transmission constraints may allow about 1,700 MW of new renewable power to be developed and delivered to electric customers in Ontario.
