Equipment Type: Fuel Rack
Abstract: A typical high density fuel storage rack, as described in , is a cellular structure supported on a set of pedestals. The bottom extremity of each storage cell is welded to a common baseplate which serves to provide the support surface for the stored nuclear fuel. The cellular region consists of a set of narrow prismatic cavities each sized to accept a single fuel assembly. The term “active fuel region” denotes the vertical space above the baseplate where the enriched uranium is located. A principal safety function of the fuel rack is to protect the geometry of the “active fuel region” from being affected under any credible accident event, the most severe of them is the plant’s postulated earthquake events.
