[0050] In the assembly and disassembly method of the fusion and fission cladding refueling system of the present invention, the fusion and fission cladding includes several identical cladding modules, including the steps of installing the cladding module and disassembling the cladding module, and installing the cladding module:

[0051] a. Install the hoop trolley 4 on the radial trolley 3, install the cladding module 3 on the hoop trolley, and the hydraulic cylinder on the hoop trolley lifts the cladding module to prevent the cladding module from contacting the ground. A positioning bump of corresponding length is installed on the hoop trolley;

[0052] b. Make the radial trolley 3 move to the set position along the radial track 1 to the circular track 2, make the circular trolley 4 cooperate with the circular track 2, and make the circular trolley 4 move along the circular track 2 to install each cladding module In step b, make the radial trolley 3 move to the set position along the radial track 1 to the circular track 2 to move the radial trolley to the base opening 501, that is, move the radial trolley to the rack 303 Connect with the outer rack 203, so that the first rack meshes with the upper ring rack, the second gear 404 meshes with the inner rack 204, and the sub-rack 303 meshes with the third gear 405;

[0053] c. Control the first gear, the second gear and the third gear to rotate synchronously, so as to drive the hoop to move to the trolley. After the hoop trolley 4 moves to the position where the cladding module is installed, the positioning block fits with the positioning bump and passes the sensor Send a feedback signal to the gear drive motor to stop the drive motor, thereby positioning the cladding module.

The welding robot welds the pipes, and then controls the rotation of the first gear, the second gear and the third gear, so that the hoop trolley withdraws from the bottom of the cladding module ;

[0054] d. Control the circular trolley 4 to move back to the radial trolley 3 along the circular track 2, control the radial trolley 3 to return to the starting point on the radial track 1, and install the next cladding module on the circular trolley 4 , to install the next cladding module;

[0055] e. Repeat steps a, b, c and d until the penultimate cladding module 3 is installed, then remove the radial trolley 3, and install the cladding installation part 6 on the radial rail 1, so that the cladding is installed Part 6 moves to the installation position of the last cladding module 3, that is, the base opening position of the base 5, and then installs the welding trolley 7 on the radial rail 1, so that the welding trolley moves to the outside of the cladding installation part 6, and controls The mechanical arm welds the pipeline in the cladding installation part 6 with the external circulation pipeline, then withdraws the welding trolley, and then drives out the strut installed between the inner and outer shielding layers through a hydraulic rod to withstand the cladding module, thereby Provide horizontal and vertical pressure to the cladding module to complete the installation of the entire cladding system;

[0057] Removing the cladding module is opposite to the process of installing the cladding module. f. Remove the last cladding module installed first, that is, first move the welding trolley to the outside of the cladding installation part 6 and use the mechanical arm to remove the cladding module on the cladding installation part 6. The pipeline is cut from the external circulation pipeline, and then the cladding installation part 6 is moved to the outermost end of the radial guide rail, the cladding installation part 6 is removed, and the radial trolley 3 equipped with the hoop trolley 4 is installed on the On the radial track 1; when the cladding module is disassembled, the fission products in the cladding module will continue to decay and generate heat, which means that the temperature of the module will continue to rise during the disassembly process, causing some safety hazards and increasing the difficulty of disassembly. When the cladding module is installed, after closing the valve of the cladding module and the main pipeline, the reserved pipeline of the cladding module is connected with the reserved pipeline on the water tank on the hoop trolley, and the water pump drives the water in the water tank to enter the cladding module to circulate the cladding module After cooling, the ring trolley disassembles and transports the module out, pumps out the hot water from the water tank and injects cold water to prepare for the next module to be disassembled. The cooling water tank is in the shape of a cuboid and is installed on the back of the hoop trolley. Two reserved pipes protrude from the water tank.

[0058] g. Move the radial trolley 3 to the position of the base opening 501, move the circular trolley 4 to the bottom of each cladding module, control the hydraulic cylinder to lift the cladding module, and then move the circular trolley 4 to the radial trolley (3) On, move the radial trolley 3 to the outer end of the radial track 1, and remove the cladding module 8;

[0059] h. Repeat step g to remove all cladding modules.
