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.

New 300-MW Coal Unit Dedicated in Missouri

LCG, November 17, 2010--City Utilities of Springfield (CU) last Wednesday dedicated and synched to the grid Southwest Power Station Unit 2, a 300-MW coal unit located in Springfield, Missouri. Following additional testing, commercial operation is scheduled to commence in early January.

The coal-fired project, which cost $697 million (including financing), was built following persistent opposition to the plant. Springfield voters turned down the municipal power project in August 2004, but later approved the project in June 2006.

The President and CEO of the American Public Power Association attended the event and stated, "We are currently having a national debate about the merits of different power resources - coal, natural gas, renewable, nuclear and energy efficiency. But the fact, is that we need all of them, including coal, to maintain a diverse, reliable power supply. The state-of-the art technology built into SW2 assures that its power will not only be affordable and reliable, but will also meet the strictest emissions standards."
