• Method for storing the cut fuel debris

Plant information	Specification of canister Location and amount of fuel debris

Determination of temporary storage location

• Assumption of specification of canister
• Temporary storage for canisters
  (basically SFP should be used)

Plant information	Atmospheric environment inside PCV (temp, dose rate, etc.) Specification of canister Work space on the operation floor (Plain view)

Transporting method for canister

• Layout of canisters setting at temporary storage
