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.

Companies Launch Voluntary Emission Trading Exchange

LCG, Jan. 17, 2002--A consortium of mostly US-based companies, as well as the cities Chicago and Mexico City, have announced their membership this week in the Chicago Climate Exchange (CCX), a voluntary organization whose members will trade allowances to emit greenhouse gases as part of a four-year pilot program.

Organized by Dr. Richard Sandor, who set up the international market in interest-rate derivatives, the exchange includes as founding members American Electric Power (AEP), Manitoba Hydro and BP, among others. Participants agree to a binding, aggregate reduction of 4 percent in greenhouse emissions compared with 1998-2001 averages, to be achieved by 2006. One reason for the participation of some members with operations in multiple countries is a desire to receive credit for overall reductions under the Kyoto Protocol, rather than needing to meet specific requirements within the borders of each participating country. The Kyoto Protocol, by which countries would be bound to reduce greenhouse emissions below 1990 levels, now requires Russia as a signatory to become enacted.

The CCX would allow credit for offsets as well as reductions of emissions. These could be achieved by non-carbon-based renewable energy development, eliminating the release of methane from landfills or agricultural operations, and by planting trees, mainly if not exclusively in the US and Brazil. Overall, the companies involved in the legally binding agreement emit 700 million tons of carbon dioxide annually. Trading will be faciliated by an Internet-based platform.

Many of the companies involved, which include Dupont and Ford Motor Company, would like to influence how any mandatory "cap-and-trade" programs covering greenhouse emissions in the US are implemented, and hope that experience gained in the CCX will serve as an advantage, should such legislation be enacted.
