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).

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.

Springfield Citizens Vote Down New Power Plant

LCG, August 4, 2004--In an unusual set-back for a municipal power provider, voters in Springfield, Missouri yesterday voted down a new, coal-fired power plant proposed by City Utilities of Springfield (CU). The 300-MW plant was estimated to cost $578.5 million and was proposed to meet Springfield's growing demands for power, which CU officials forecast will exceed CU's supplies by 2007 or 2008.

The vote was 19,587 for and 21,073 against the plant, with all Greene County precincts reporting. Voters were deciding whether to accept a 16 percent electric rate increase spread over four years to help pay for the new, Southwest 2 plant. Door-to-door campaigning was heavy, with labor union members and the Springfield Area Chamber of Commerce supporting the plant. Opponents of the proposed plant included Rate Payers for Affordable Utilities, who questioned the need. CU was not allowed to campaign directly.

With the proposed plant rejected, CU will need to develop a new plan acceptable to its citizens to serve the growing power demands of the area.
