摘　　要：核电厂大修或日常期间,水池区域可能会产生异物,由于核电厂结构复杂,又兼具了辐射、水下、高温、高压等特点,给水下异物打捞工作带来了极大的困难。本文对异物落入水池进行了风险分析,并结合秦山压水堆核电厂的水下异物打捞经验,阐述了不同情况下打捞异物的方法,总结了目前采取的防异物措施,为国内外压水堆核电厂水池边防异物措施和水下异物打捞提供指导和借鉴。During the overhaul or daily period of nuclear power plant,there may be foreign matters in the pool area.Because of the complex structure of nuclear power plant and the characteristics of radiation,underwater,high temperature and high pressure,the salvage of foreign matters under water supply has brought great difficulties.In this paper,the risk analysis of foreign matters falling into the pool is carried out.Combined with the underwater foreign matter salvage experience of Qinshan nuclear power plant,the methods of foreign matter salvage under different conditions are described,and methods to prevent the foreign matters from falling that we can adopt at present are summarized,which can provide reference and guidance for the underwater foreign matter salvage work of nuclear power plant.
