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.

Eight Utilities Propose Energy Efficiency Investments to Reduce Carbon Emissions

LCG, September 28, 2007--Eight major electric utilities are proposing energy efficiency as a means to reduce future carbon (and other) emissions while serving customers. Duke, Con Edison, Edison International, Great Plains Energy, Pepco Holdings Inc., PNM Resources, Sierra Pacific Resources and Xcel Energy yesterday announced a proposal to increase their investment in energy efficiency by $500 million per year to $1.5 billion if they can achieve regulatory changes to encourage conservation.

Jim Rogers, chairman, president and chief executive officer of Duke Energy stated, "There has been a chronic underinvestment in energy efficiency in our country. We are determined to fix that, by creating the innovative regulatory frameworks that leverage technology to address climate change, reduce power demand and keep our customers' power bills as low as possible."

Collectively, the eight utilities serve almost 20 million customers in twenty-two states. Together, they plan to invest approximately $1 billion annually over the next 3 years and about $1.5 billion annually in years four through ten, with an expectation to reduce carbon dioxide emissions approximately 30 million tons annually in the latter years. The utilities propose to work collaboratively with policymakers and other stakeholders to overcome regulatory barriers that may discourage utility investment in energy efficiency today.

The eight utilities, along with the Edison Electric Institute, also plan to create a new organization, the Institute for Electric Efficiency (IEE), that will promote the sharing of information, ideas and experiences on effective means of delivering energy efficiency.
