A kind of underwater high-radioactive foreign body multifunctional suction container and salvage process

Abstract

The invention relates to a multifunctional absorbing vessel used for absorbing an underwater highly radioactive foreign matter and a fishing technology. According to the fishing technology, an underwater dust collector is used cooperatively with a fishing tool to perform fishing of the highly radioactive foreign matter under a water shielding working condition, and the highly radioactive foreign matter can be preserved in the fishing tool so that analysis and evidence obtaining work can be conveniently carried out after the fishing process. According to the multifunctional absorbing vessel used for absorbing the underwater highly radioactive foreign matter and the fishing technology, a large-scale radioactive foreign matter shielding flask does not need to be prepared, the fished highly radioactive foreign matter can be conveyed to a spentfuel storage pool for temporary storage, and the highly radioactive foreign matter can be taken out from the spentfuel storage pool at any time when needed, so that the highly radioactive foreign matter is subjected to evidence obtaining and analysis. According to the fishing technology, long time limit for a project and a large amount of cost in processing equipment for highly radioactive waste in a later period are saved, and convenient conditions for technological analysis in the later period are provided.

Description

technical field [0001] The invention relates to an underwater high-radioactive foreign matter multi-functional suction container and a salvage process. The process can complete the salvage of high-radioactive foreign matter under the working condition of water shielding by using an underwater vacuum cleaner and a salvage tool, and can keep the high-radioactive foreign matter in the In the salvage tool, in order to carry out the analysis and evidence collection work after salvage. Background technique [0002] During the operation and overhaul of nuclear power plants, it is inevitable for maintenance personnel to salvage underwater foreign objects, especially when the water level in the refueling pool is high during the overhaul of the power plant, high radioactive foreign objects appear in the core area and must be dealt with . However, once a foreign object appears in the operating system of the power plant, it will become a great hidden danger to the safe and stable opera...

AI Technical Summary

Problems solved by technology

It is impossible to transfer or dispose of these foreign objects except by using a large lead shielding container, and the large lead shielding container requires the calculation, demonstration, design of the design institute, and finds a manufacturer to customize it, which requires a lot of money and time. If only a small piece of high radioactive The preparation of a large lead shielding container for foreign matter also brings great pressure to the later stage of radioactive waste disposal. At the same time, the daily storage and management of large lead shielding containers with high radioactive foreign matter also presents high risks
