Description

Technical Field

[0001] The utility model relates to the technical field of radioactive waste treatment, in particular to a manual operation device for a HIC gripper. Background Art

[0002] During the operation and maintenance of nuclear power plants, radioactive solid wastes such as spent ion exchange resins, spent filter cartridges, spent activated carbon, and zeolites are generated. Nuclear power plants need to select reasonable waste treatment processes to meet the requirements of waste minimization and control of the total amount of packaged waste.

[0003] At present, the site waste treatment facilities (SRTF) and radioactive solid waste treatment systems designed for AP1000 nuclear power plants are used to treat and dispose of radioactive solid wastes such as spent resins, spent activated carbon, zeolites, and spent filter cartridges. Among them, solid wastes such as spent resins and zeolites are first flushed by water to the storage tank of the radioactive solid waste treatment system, and then transported by water to the resin-type high-integrity container (HIC). When the high-integrity container (HIC) reaches the high liquid level, it will stop receiving. After dehydration treatment, it is transported to the HIC storage well in the HIC temporary storage of the site waste treatment facility through a shielded transport container; the spent filter cartridges are transported to the radioactive waste plant through a transfer container, stored and drained, filled into a water filter-type high-integrity container, and transported to the HIC storage well in the HIC temporary storage of the site waste treatment facility through a shielded transport container.

[0004] Among them, the operations of transferring the high-integrity container (HIC) to the shielded transport container and transferring the high-integrity container (HIC) from the shielded transport container to the HIC storage well in the prior art need to be operated through the HIC gripper. The gripper consists of equipment such as pin claws, a locking device, a control motor, and a transmission mechanism. When the HIC is transported, the traveling crane suspends the gripper through a hook to align with the HIC cover, and the control motor controls the pin claws to lock the HIC cover and complete the lifting and transportation of the HIC. However, the above HIC lifting operation has the following risks and problems: during the HIC lifting operation, the control motor fails, resulting in the pin claws of the HIC gripper being unable to release after being locked; due to the high positions of the shielded transport container and the HIC storage well, it is difficult for the operator to manually handle the failure; and the HIC has a high radiation dose, which will increase the radiation dose received by the staff when manually handling the failure.
