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.

Long Island Getting Juice from 18 Fuel Cells

LCG, Nov. 1, 2001--Fuel cell maker Plug Power Inc. said yesterday that 18 of its proton exchange membrane generators have been fully installed at a Babylon, N.Y., substation owned by New York State's Long Island Power Authority and are supplying power to the local transmission grid.

The 18 are part of a project that will eventually have 75 of the fuel cells hooked up, the company said. So far, 55 have been installed. The project is part of an initiative proposed by New York Gov. George Pataki as a way to promote new energy techniques and energy conservation projects.

According to Plug Power, the fuel cells could produce as much as one million kilowatt-hours of electricity over the duration of the program, which is enough electricity to power about 100 average-sized homes.

LIPA Chairman Richard M. Kessel said "Fuel cells are an environmentally friendly electric generating technology, and this project will help us develop a better understanding of how fuel cells can be integrated into our electric grid."

A fuel cell is a device that converts the energy of a fuel such as hydrogen, natural gas, methanol or gasoline and an oxidant which can simply be air into useable electricity through an electrochemical process from which no particulate matter is produced.

Locally, the fuel cells were well received. "The town of Babylon recognizes the need to look toward alternative fuel technologies as a way of supplying clean, efficient power for the future," said Babylon Town Councilman Steve Bellone.

The program is being funded through LIPA's Clean Energy Initiative, a five-year, $170 million program designed, in part, to foster the development and application of clean energy technologies, such as fuel cells, solar, wind generation and geothermal systems, Plug Power said.
