Description

Technical Field

[0001] The utility model relates to the technical field of radioactive waste cleaning, in particular to a device for cleaning the bottom and wall of a refueling pool of radioactive waste. Background Art

[0002] Nuclear power plant refueling pools require regular unloading and loading operations. After long-term operation, corrosion activation products containing radioactive substances are generated within the pools, adhering to the pool bottom and walls. During each major overhaul, some maintenance work requires personnel to work below the pool bottom. To reduce radiation doses and the risk of contamination to maintenance personnel, the pool bottom and walls must be cleaned and decontaminated before they begin their work. This ensures a clean and safe working environment for maintenance personnel and the environment, ensuring radiation safety for both personnel and the environment. Currently, three common decontamination techniques for refueling pools in nuclear power plants are mechanical decontamination, chemical decontamination, and chemical-mechanical decontamination. Mechanical decontamination uses cleaning tools (such as scrapers, mops, scrapers, and submersible pumps); chemical decontamination uses chemical cleaning agents; and chemical-mechanical decontamination combines mechanical and chemical decontamination to achieve decontamination. All three existing technologies require nuclear cleaning personnel to manually clean the pool floor and walls, which not only results in high radiation doses, high workload and low efficiency for nuclear cleaning personnel, but also occupies the critical path for overhaul. Incomplete cleaning leads to unplanned increases in radiation doses for maintenance personnel.

[0003] To this end, the utility model addresses the current problem that manual cleaning of the walls of nuclear power plant refueling pools results in high radiation doses to personnel and occupies the key path of overhaul. It carries out research on equipment for cleaning radioactive attachments on stainless steel walls, focusing on breakthroughs in the attachment cleaning process and attachment collection process technology, replacing the existing purely manual cleaning method, and achieving efficient cleaning of the pool walls, thereby reducing the radiation dose to personnel and the time occupied in the key path of overhaul, and solving the above-mentioned problems.
