DYNAMIC RESPONSE OF CRACKED HEXAGONAL SUBASSEMBLY DUCTS.
Journal Article (Journal Article)
The hexagonal subassembly ducts (hexcans) of current Liquid Metal Fast Breeder Reactor (LMFBR) designs are typically made of 20% coldworked Type 316 stainless steel. Prolonged exposure of this initially tough and ductile material to a fast neutron flux at high temperatures can result in severe embrittlement. This paper examines the dynamic elastic response of flawed and unflawed fast reactor sub-assembly ducts. A plane-strain finite element analysis was performed for ducts containing internal corner cracks, as well as external midflat cracks.
