Automatic shielding door of spent fuel transport ship

Abstract

The invention relates to an automatic shielding door structure of a spent fuel transport ship, and belongs to the technical field of ships. The automatic shielding door structure comprises a door body and a door frame, the door frame is arranged on the side face of a cabin body, the door body is installed on the door frame of the cabin body, the door body is opened or closed on the door frame of the cabin body, the door body is completely covered with a shielding layer used for preventing radiation, the shielding layer and the door body are fixed together, and a sealing plate for protecting the shielding layer of the door body is additionally arranged outside the shielding layer of the door body. Compared with the prior art, the automatic shielding door structure of the spent fuel transport ship has the beneficial effects that as the shielding layer for preventing radiation is arranged on the door body, so that on the premise that the water tightness of the door body is not reduced, the door body further has good anti-radiation shielding performance, crews can conveniently move in a cabin, the time for exposing the crews in a radiation area is shortened, more safety and reliability are achieved, the structure is simple, and manufacturing and installation are convenient.

Description

technical field [0001] The invention relates to a shielding structure of a spent fuel transport ship, in particular to an automatic screen door structure of a spent fuel transport ship, and the invention belongs to the technical field of ships. Background technique [0002] Due to the reduction of traditional energy, clean energy will gradually replace traditional energy, and the application of nuclear energy will become more and more extensive. Generally, the fuel storage tanks of nuclear energy nuclear power plants have limited capacity, which can generally only meet the storage needs of spent fuel unloaded within more than ten years, while the design life of nuclear power plants is generally 40-60 years. At present, many nuclear power plants in my country are already facing the problem of insufficient in-plant storage capacity. In the future, the amount of spent fuel produced in my country will continue to increase year by year. Therefore, the safe transportation of spent...

Problems solved by technology

[0006] Since the original function of the cargo door needs to be watertight, the existing cargo door does not have the function of shielding radiation, thus weakening the penetration of the cargo door to the local shielding, which will cause radioactive particles such as neutrons and gamma rays in the cargo cabin to penetrate the area through the cargo door Radiation leakage beams are formed to reach the outside of the cargo hold, and further reach the upper deck area through the cargo hold passage, resulting in radiation hotspots in local areas, thereby limiting staff access and area management
