Abstract
The automatic modeling of fault tree for nuclear power safety I&C configuration is designed to meet the requirements of reducing the workload and improving the traceability during the nuclear power safety I&C system reliability assessment work. To complete the fault tree automatic modeling, the Visio Automation software technology is used to analyze the topology of the nuclear power safety I&C system hardware device and software function. The good result in practical implementations shows that the nuclear power safety I&C system fault tree modeling work is successfully simplified.

Summary
This paper takes nuclear power safety Instrumentation and Control system, or I&C system for short, as the modeling object. In ordinary verification modeling process, fault trees are built manually after analyzing the topology of hardware and the function of the software, which becomes time-consuming, and inconsistent with style, coding, assumption and other factors. To make it worse, the errors usually occur during the manual modeling process gradually. Visio Automation software technology is used to analyze the topology of the nuclear power safety I&C system hardware device and software function to complete the fault tree automatic modeling work [6]. The good result in practical implementations shows that the nuclear power safety I&C system fault tree modeling work is successfully simplified
