초록
A multi-purpose canister (MPC) was developed for the purpose of transportation, storageand disposal of spent nuclear fuel (SNF) and has the advantage of minimizing repackaging betweenmanagement stages of SNF. Considering the typical rock characteristics in Korea, a disposal canisteris expected to contain 4 assemblies of Pressurized water reactor (PWR) SNF. The capacity of the MPCshould be similarly designed with the disposal canister. However, the MPC with four SNF assemblies isexpected to be less efficient in transporting and storing compared to a large-capacity canister. Therefore,a preliminary concept was derived for an auxiliary equipment that can transport and store multiple MPCsin a large overpack. A previously derived concept from US was thoroughly reviewed, and the preliminaryconcept was revised considering domestic situations including crane capacity and others. In addition,the safety of the normal transportation and storage of the MPC placed in transportation and storageoverpack was evaluated with the auxiliary equipment.
