Description

Technical Field

[0001] The utility model relates to the technical field of nuclear engineering, in particular to a disturbance device of a fast retrieval device of a spent fuel storage system. Background Art

[0002] As a fourth-generation advanced reactor type, the high-temperature gas-cooled reactor is a nuclear power generation technology with complete independent intellectual property rights in my country.

[0003] During the power generation process of high-temperature gas-cooled reactors, a large amount of spent fuel will be generated. The so-called "spent fuel" refers to the used fuel elements that are unloaded after a nuclear power plant, reactor or other power reactor fuel element has been used for a refueling cycle and the burnup has reached a certain level. Spent fuel is highly radioactive and toxic and contains a large amount of highly radioactive substances. These spent fuels pose a potential threat to human safety and the ecological environment. Therefore, the spent fuel needs to be processed. The process of processing spent fuel is called spent fuel reprocessing, which aims to recover and utilize useful materials in spent fuel and reduce the amount of radioactive waste that ultimately needs to be processed.

[0004] In the spent fuel reprocessing of high-temperature gas-cooled reactors, radioactive graphite balls are a type of spent fuel that needs to be processed. The radioactive graphite balls need to be taken out of the storage tanks for recycling. Considering the destructive effects of nuclear radiation on human health, the retrieval of radioactive graphite balls should not be done manually and needs to be fully automated.

[0005] Now, a spent fuel rapid retrieval device is usually used to retrieve the radioactive graphite balls in the storage tank. The spent fuel rapid retrieval device includes a ball suction tube, one end of which is connected to the storage tank, and the other end of the ball suction tube is connected to the negative pressure device. By controlling the operation of the negative pressure device, the radioactive graphite balls are sucked out of the storage tank.

[0006] In actual application of the spent fuel rapid retrieval device, since the connection between the input end of the ball suction tube and the storage tank is fixed and the axial direction of the input end of the ball suction tube is fixed, the ball suction tube can only retrieve radioactive graphite balls in a certain area in the storage tank, resulting in a low retrieval rate of radioactive graphite balls in the spent fuel rapid retrieval device under fully automated conditions, that is, all radioactive graphite balls cannot be taken out of the storage tank during the fully automated retrieval process.

[0007] The utility model aims to provide a disturbance device suitable for a spent fuel rapid retrieval device, a nuclear fuel rapid retrieval device and a graphite ball rapid retrieval device, and is used to improve the retrieval rate of spent fuel, nuclear fuel and radioactive graphite balls.
