Heavy water reactor spent fuel dry storage shielded transport container

Abstract

The invention belongs to the technical field of heavy water reactor spent fuel dry-type storage shielding shipping container and in particular relates to a heavy water reactor spent fuel dry-type storage shielding shipping container. Two ends of a lifting yoke assembly of the heavy water reactor spent fuel dry-type storage shielding shipping container are respectively connected with two opposite sides of a shielding barrel; an electric chain hoist is arranged at the lower end of the middle part of the lifting yoke assembly, the chain of the electric chain hoist is connected with one end of a gripper head adapter, the other end of the gripper head adapter is connected with a gripper head, and the gripper head adapter and the gripper head are arranged in the shielding barrel; one side of the lower part of the shielding barrel is provided with a rectangular translation gate slot, rails are arranged the left side and right side of the translation gate slot, a rail extension structure is arranged outside the shielding barrel, two rails are paved onto the rail extension structure from the interior of the shielding barrel, a translation gate is arranged between the two rails, a translation gate driving mechanism is arranged at the rear end of the rail extension structure, the translation gate can move between the two rails under the action of the translation gate driving mechanism and can enter into the translation gate slot of the shielding barrel. The operation safety and reliability of the heavy water reactor spent fuel dry-type storage shielding shipping container are higher.

Description

technical field [0001] The invention belongs to the technical field of heavy water reactor spent fuel dry storage, in particular to a heavy water reactor spent fuel dry storage shielding transport container. Background technique [0002] With the operation of heavy water reactors, a large amount of spent fuel will be produced. The spent fuel produced by the heavy water reactor is stored in the spent fuel pool after unloading. However, the spent fuel pool will eventually be filled, so the problem of the outlet of the spent fuel must be solved, otherwise the normal operation of the nuclear power plant will be seriously affected. [0003] At present, the international solution to the way out of spent fuel is to use the method of temporary dry storage of spent fuel from heavy water reactors in nuclear power plants, that is, to build dry storage modules for spent fuel from heavy water reactors. The outside of the storage module is a rectangular reinforced concrete structure. Ea...
