US lab tests GE Vernova nuclear fuel after 6 years in commercial use

Scientists at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have begun analyzing advanced nuclear fuel rods developed by Global Nuclear Fuel (GNF), a GE Vernova-led joint venture with Hitachi Ltd., after six years of commercial reactor use. These high burnup fuel rods, designed to enhance nuclear reactor efficiency and reduce spent fuel waste, were manufactured at GNF’s Wilmington, NC facility and operated through extended cycles beyond current US Nuclear Regulatory Commission (NRC) licensing limits. The examination at PNNL aims to assess the fuel and cladding performance after prolonged reactor exposure, supporting ongoing development under the DOE’s Accident Tolerant Fuel program. High burnup fuels utilize more fissile material, allowing reactors to operate longer and more efficiently while generating less nuclear waste, which improves fuel cycle economics and safety. The advanced fuel is expected to remain in reactor cores for extended periods, potentially enabling fuel cycle lengths of 36-48 months. GE Vernova plans to use this fuel design
