Abstract

The assessment method for software of computer based Instrumentation & Control (I&C) system is one of the major sticking points in Probabilistic Safety Assessment (PSA) of Nuclear Power Plant (NPP). This paper introduces a conservative method of cut-off value for software modeling of computer based I&C system to consider the impaction of software in the PSA modeling, and sensitivity study of software is performed to analyze the significance of each software part of computer based I&C system. Finally, a case study is presented to show how to model the software and perform sensitivity study.
