Joint NEA project performs high-burnup test
An article in the OECD Nuclear Energy Agency’s July news bulletin noted that a first test has been completed for the High Burnup Experiments in Reactivity Initiated Accident (HERA) project. The project aim is to understand the performance of light water reactor fuel at high burnup under reactivity-initiated accidents (RIA).

Advanced manufacturing (AM) is a disruptive manufacturing process often referred to as “the next industrial revolution” because of its ability to fabricate components with complex geometries and site-specific materials and properties. While other industries, like automotive, aerospace, and fossil-fired power companies, are adopting and evaluating AM processes, the nuclear industry, including the fusion materials community, has been somewhat slow to capitalize on the seemingly beneficial aspects of AM. To address this gap, Oak Ridge National Laboratory is evaluating candidate AM techniques to fabricate nuclear-relevant materials including ferritic-martensitic (FM) steels. This paper discusses the development of a road map for AM approaches for FM steels. Specifically, the connection among alloy composition, additive processes, processing conditions, and postprocessing and the resulting microstructure using both wire-based and powder-based directed energy deposition techniques is detailed. Finally, strategies to develop specialized alloys for additive manufacturing are outlined.
