摘　　要：我国已投运的核电厂陆续发生海洋异物入侵导致取水系统堵塞的运行事件,对机组的运行产生了较大影响,甚至可能会威胁核电厂的最终热阱安全.本文选取某一典型的取水口堵塞事件,利用屏障分析法列出所有能够防止事件发生的物理屏障和管理屏障,并对相关屏障失效进行分析,从而找出事件发生的根本原因,为后续预防此类事件提出指导建议.The abnormal blockage of the water intake system caused by the invasion of foreign bodies in the ocean has occurred one after another at the sites of nuclear power plants in China,which has a great impact on the operation of the units,even may threaten the safety of the nuclear power plant s final heat sink.This paper selects a typical water intake blockage incident,uses barrier analysis to list all physical barriers and management barriers that can prevent incidents,and analyzes the failure of related barriers to find out the root cause of the incident.And provide guidance for preventing such incidents.

关 键 词：屏障分析法 核电厂运行事件 根本原因分析
