Abstract: In response to the treatment requirements of radioactive waste filter cartridge, two sets of volume reduction devices for waste filter cartridge have been developed. The first device adopts the "overall crushing and compression" process, which crushes and compresses the waste filter cartridge as a whole. This device significantly reduces the volume of the waste and provides technical support for waste minimization. During the use of the filter, most of the radioactive dust and aerosols are retained on the cartridge material, while the metal shell is lightly contaminated mainly on the surface and can be decontaminated and reused through cleaning. The second device was developed to adopt different treatment measures for the metal frame and cartridge material. The second device uses a step-by-step processing method of "separation and compression". That is, separating the cartridge material and the metal frame, and the cartridge material is reduced in volume through compression, while the metal frame is cleaned of the outer surface by processes such as adhesive removal and wiping, with the aim for clearance or preparation. The waste filter cartridge volume reduction device of separating and compressing the filter cartridge can effectively reduce the volume of the waste filter cartridge, and has the advantages of high automation, good vovlume reduction effect, and high radiation protection effctiveness.
