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.

Iceland Chooses Hydrogen

LCG, June 3, 2002-Iceland has decided to phase out fossil fuels, choosing to power the country by means of hydrogen fuel cells.

Iceland, which is home to a mere 278,000, already powers 93 percent of homes with geothermal-derived electricity. Now the country will switch its vehicles to hydrogen, with the help of DaimlerChryler, Royal Dutch Shell, and Norsk Hydro. The three companies will invest in the newly-created Icelandic New Energy.

Hydrogen fuel, which produces water as its only exhaust, will be produced relatively emission-free by way of hydroelectric and geothermal sources.

DaimlerChrysler is responsible for the design of new Icelandic buses, which will be in service next year.

Iceland is more ambitious than merely converting the buses, however, and plans eliminate the need for fossil fuel from its 180,000 vehicles over a period of 30 or 40 years.

Icelandic electricity production is already clean, but the country suffers from high carbon dioxide emissions because of its metal smelting industry.

Although hydrogen, when used as a fuel, is a pollution-free energy source, the volatile element needs to be obtained by some method usually requiring a lot of energy since hydrogen does not easily exist alone and unreacted in nature. Electrolysis separates water with the help of electricity yielding oxygen and hydrogen, which is the reverse reaction of hydrogen when it acts as a fuel producing electricity and water. Other sources of hydrogen, such as hydrogen-producing algae, are currently being researched.
