Behavior of High-Density Spent-Fuel Storage Racks

摘要

Included in this report is a summary of information on neutron-absorbing materials such as B sub 4 C in an aluminum matrix or organic binder material, stainless steel-boron and aluminum-boron alloys, and stainless steetl-clad cadmium that are used in high-density spent fuel storage racks. A list of the types of neutron-absorbing materials being used in spent fuel storage racks at domestic commercial plants is provided. Recent cases at several domestic plants where swelling of rack side plates (where the B sub 4 C in an aluminum matrix and B sub 4 C in an organic binder material were located) occurred are reviewed.
