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.

Rhode Island Legislature Passes Revisions to Increase RPS Goals to 40 Percent

LCG, June 28, 2016--The Rhode Island legislature last week passed legislation to increase the state's renewable energy target from 14.5 percent by 2019 to 40 percent by 2035. The legislation is expected to be signed into law by Governor Gina Raimondo.

The legislation proposes to revise Rhode Island's original renewable portfolio standard (RPS) approved in June 2004. The original RPS targeted 3 percent renewable energy by 2007; it would then rise an additional 0.5 percent through 2010, an additional 1.0 percent through 2014, and an additional 1.5 percent of renewable energy each year through 2019, when it would reach 16 percent. However, in December 2014, the PUC decided to delay the 1.5 percent increase for 2015 by one year, thus reducing the 2019 goal from 16 percent to 14.5 percent.

A House amendment attached to the new legislation gives the PUC more flexibility to delay a planned increase in the RPS in the event of an inadequate supply of renewable energy credits.

Last month, Maryland Governor Larry Hogan vetoed legislation that would increase the state's RPS from 20% to 25% by 2020. According to the Governor, Maryland consumers in 2014 paid over $104 million for renewable energy credits, and the higher standard would increase the burden on ratepayers. The tax increases were estimated to be up to $196 million in 2020 under the proposed legislation.
