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.

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.

NuScale Power Receives Design Approval from the NRC for Small Modular Reactor
LCG, August 28, 2020--NuScale Power announced today that the U.S. Nuclear Regulatory Commission (NRC) completed the last and final review (Phase 6) of the Design Certification Application (DCA) for the company’s small modular reactor (SMR) with the issuance of the Final Safety Evaluation Report (FSER). The FSER represents completion of the technical review and approval of the NuScale SMR design. With this final phase of NuScale’s DCA now complete, customers can proceed with plans to develop NuScale power plants with the understanding that the NRC has approved the safety aspects of the NuScale design.
NuScale's new SMR is a light water reactor design that features a fully factory-fabricated NuScale Power Module™ capable of generating 60 MW of electricity using a safer, smaller, and scalable version of pressurized water reactor (PWR) technology. The scalable design can house up to 12 individual power modules at a power plant. The scalable design provides the benefits of carbon-free energy and reduces the financial commitments associated with gigawatt-sized nuclear power projects. The majority investor in NuScale is Fluor Corporation.
NuScale's Chairman and Chief Executive Officer stated, "This is a significant milestone not only for NuScale, but also for the entire U.S. nuclear sector and the other advanced nuclear technologies that will follow. This clearly establishes the leadership of NuScale and the U.S. in the race to bring SMRs to market. The approval of NuScale’s design is an incredible accomplishment and we would like to extend our deepest thanks to the NRC for their comprehensive review, to the U.S. Department of Energy (DOE) for its continued commitment to our successful private-public partnership to bring the country’s first SMR to market, and to the many other individuals who have dedicated countless hours to make this extraordinary moment a reality. Additionally, the cost-shared funding provided by Congress over the past several years has accelerated NuScale’s advancement through the NRC Design Certification process. This is what DOE’s SMR Program was created to do, and our success is credited to strong bipartisan support from Congress."
The DCA was completed in December 2016 and accepted by the NRC in March 2017. NuScale's Vice President of Regulatory Affairs stated, "The NRC embraced the challenge of reviewing the first-ever small modular reactor DCA, which at the time not only marked an important milestone for NuScale, but also for the nuclear industry as a whole. NuScale appreciates the dedication, time, and effort of the NRC throughout this multi-year process, often with reviews completing ahead of schedule."
NuScale states that it fields growing domestic and international customer interest from those who see the NuScale power plant as a long-term solution for providing reliable, safe, affordable, and operationally flexible carbon-free energy for diverse applications. NuScale has signed agreements with entities in the U.S., Canada, Romania, the Czech Republic, and Jordan. Similar agreements with other entities are being negotiated.
