Abstract

The invention provides a radioactive waste resin shielding transfer method and device. The radioactive waste resin shielding transfer method comprises the resin loading step which comprises inputting the resin to a resin storage tank from a nuclear island plant through a resin conveying pipeline due to the radioactive waste resin shielding transfer device; the resin storage tank water removal step which comprises inputting the water in the resin storage tank to the nuclear island plant through a water removal pipeline; the conveying step which comprises conveying the resin shielding transfer device to factory site waste treatment devices; the resin unloading step which comprises displacing the resin to the factory site waste treatment devices from the resin storage tank by a volumetric water displacement unloading process. The integral process of shielding transfer of the waste resin can be effectively implemented through the radioactive waste resin shielding transfer device and the series of steps and meanwhile the leakage conditions of radioactive substances can be detected in the transfer process.

Description

technical field [0001] The invention relates to a method for shielding and transferring waste resin, in particular to a method for shielding and transferring radioactive waste resin in a nuclear power plant area and a transfer device thereof. Background technique [0002] Ion exchange resins are often used for purification treatment of nuclear power plant reactor primary circuit coolant and spent fuel pool water. When the exchange capacity of ion exchange resin decreases, the resin bed cannot achieve the required purification effect or the pressure difference between the two ends of the exchange column reaches The resin needs to be replaced when the value reaches a certain value, so nuclear power plants produce a considerable amount of radioactive waste resin every year. The water content of waste resin is generally 50%-60%, and it is concentrated in fission products and activation products such as strontium and cesium. It belongs to low and medium level radioactive wet wast...
