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.

US Signs Energy Research Agreement with European Union

LCG, March 6, 2003Today EU and US officials agreed to have scientists join efforts in hydrogen and nuclear power research.

Spencer Abraham, the U.S. Secretary of Energy, signed a pact with the European Union in the office of EU Research Commissioner Philippe Busquin.

According to the agreement, researchers studying nuclear fission, nuclear fusion, hydrogen power, and carbon dioxide removal will be able to work together in order to quicken technology development.

While the document says nothing about how much money the EU or U.S. will put toward joint projects, the signing marked a new direction for the Bush administration, which pulled the U.S. out of the Kyoto Protocol in 2001 to broad internatinoal dismay.

Meanwhile the Bush administration has earmarked at least $1.5 billion in funding for hydrogen fuel cell research. Fuel cells are complicated systems in which petroleum or other hydrocarbons undergo a series of reactions, yielding water, carbon dioxide, and energy. Hydrogen, which is too reactive to survive long in elemental form in nature, can also be separated from carbon compounds and stored as gas. When elemental hydrogen reacts with oxygen, it yields energy and water vapor.

The EU and U.S. have both noted interest in turning to a hydrogen-based economy, a somewhat misleading proposition in that, according to the current direction of research, hydrogen will be derived from natural gas, coal or oil. In any case, the signing comes as part of a growing international effort to change the face of power production.
