Abstract

The invention provides a filtering element dismounting device for a radioactive water filter. The filtering element dismounting device comprises a cylindrical shielding container, a filtering element gripping apparatus and a temporary hatch cover, the shielding container is provided with a containing cavity arranged in the axial direction of the shielding container, the containing cavity forms an open butt joint port at the lower end of the shielding container, and the containing cavity forms a gripper guide hole with the caliber smaller than that of the containing cavity at the upper end of the cylindrical shielding container. The filtering element gripping apparatus comprises a rod-shaped gripping apparatus guide part and a gripping part arranged at the lower end of the gripping apparatus guide part, the gripping apparatus guide part is connected with the gripping apparatus guide hole in a sliding fit manner, and the gripping part is arranged in the containing cavity; and the temporary hatch cover is provided with a middle interface corresponding to the butt joint interface. When the filtering element is detached, the radiation dosage borne by workers can be effectively reduced, the efficiency of the detaching process is high, and a large amount of operation time can be saved.

Description

technical field [0001] The invention relates to a dismantling device for a filter element of a radioactive water filter and a transfer tool thereof, and belongs to the field of dismantling and transferring of radioactive components of a nuclear power plant. Background technique [0002] The radioactive water filter is one of the very important equipments of the nuclear power plant. As a filter device for the radioactive water circuit of the nuclear power plant, it plays the role of filtering the corrosion and activation products, fission products and other granular impurities of the primary circuit and its auxiliary system. The radioactive water filter element needs to be replaced after one cycle of operation or high pressure difference alarm before and after the filter. After being transported across multiple workshops, it is stored in the waste filter element storage pool. [0003] After long-term operation of nuclear power plants, the corrosion and activation products of ...
