[0045] First, the cup containing the radioactive material is placed into the feeding chamber 2 through the feeding sealing door 9, and the operator controls the master-slave manipulator 27 to transfer the cup into the mixing and cutting chamber 3;

[0046] In the mixing and cutting chamber 3, the operator places the material cup in the mixing device 21 by controlling the master-slave manipulator. Under the action of the mixing device 21, the radioactive materials in the mixing device 21 are evenly mixed. Then, the operator transfers the material cup to the outer cup cutting device by operating the master-slave manipulator, and the outer cup cutting device opens the outer cup of the material cup. Then, the operator transfers the opened material cup to the opening and packaging chamber 4 by controlling the master-slave manipulator 27.

[0047] In the lid opening and packaging chamber, the inner cup of the material cup is opened by the inner cup lid opening device 24, and the material dispensing device 25 repacks the radioactive material in the material cup;

[0048] Then the packed radioactive materials are transferred to the discharging glove box 5 by the master-slave manipulator 27;

[0049] When the mixing device 21 , the outer cup cutting device 23 , the inner cup cover opening device 24 , and the material dividing device 25 fail, the operator can enter the maintenance room 7 and repair or replace the above-mentioned devices through the glove hole 15 .
