摘　　要：首先对国际国内相关的标准和法规进行研究,明确仪表可用性分析的顶层要求。其次确定了5个关键可用性分析要素;在此基础上提出了一种曲线包络对比的分析方法,形成完整的分析流程。采用所提出的分析方法,能够可信地对核电厂仪表在严重事故条件下的可用性进行分析,有效提高应对严重事故的能力。对国内目前仪表可用性仍然存在的问题进行了分析,并提出了相关的技术见解。Firstly the related international and domestic standards, laws and regulations were studied, to identify the top requirements on the survivability assessment of the instruments. Secondly an assessment method of curve comparison and integrated assessment procedure were provided based on the definition of 5 key assessment factors. The proposed analysis methods can be used to assess reliably the availability of the instruments, to effectively improve its ability of handling the severe accidents. In the end, this paper analyzed the existing assessment issues in China and put forward the corresponding technical opinions.
