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.

Alberta Grid Upgrades Urged

LCG, Feb. 12, 2002--ESBI Alberta Inc. and Alberta-based power suppliers want an expansion of the province's transmission infrastructure to handle growing demand for electric power.

Most generation capacity in Alberta is found north of Red Deer. To construct new lines from the northern part of the province to the south, where demand is growing most, ESBI, which manages the transmission system for the province, would first need to obtain rights of way. According to Richard Stout, commercial manager for ESBI, "the line building itself may only take two or three years, but the acquisition of the rights of way to the land could take six or seven years."

Stout estimates that millions of dollars could be spent to obtain necessary easements, but is not sure who would be required to pay for the rights as well as the construction costs.

At least twelve power companies want more transmission lines, among them Calgary-based Enmax Corp. Enmax not only supplies local customers, but has benefitted from exports to Washington State and California. While Alberta customers currently pay for transmission upgrades through a charge on their bills, ESBI has told the Alberta Energy Utilities Board that lines for cross-border sales should be paid for by power suppliers with licenses to conduct such sales.

The Alberta Energy Utilities Board will conduct a hearing on transmission investments in late April.
