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.

Missouri Gas Asks for $39 Million Rate Hike

LCG, Nov. 8, 2000--Missouri Gas Energy Co. yesterday asked regulators for authority to raise rates by $39 million a year. The increase would be in a form that would increase householders' natural gas bills by about $5 per month regardless of how much gas they used.

The Missouri Public Service Commission has 11 months to decide whether to grant the company's request.

The company, which last raised its rates three years ago, said the increased revenues were needed to replace gas lines and install new lines to serve housing developments. Paul Snider, a spokesman for the utility, said "The bottom line is: We aren't making enough to recover our expenses and make a reasonable rate of return."

The stipulation that customers pay a higher monthly charge regardless of gas usage is like to face opposition. Doug Micheel, senior counsel with the Missouri Office of Public Counsel, said "We have traditionally been against the top-loading of fixed charges on consumers."

The rate increase would increase the flat customer service charge by $7.45 from $9.05 per month to $16.50. But the charge for energy would decrease by about $2.50 for the typical customer, resulting in a $5 increase.

Raising the customer charge would allow the utility to count on a stable flow of revenue, Snider said. He also noted that the new rate would stabilize customers' gas bills, spreading out fluctuations in the price of the commodity over 12 months.
