Abstract
Since the digital technology is used in the safety system of nuclear power plant (NPP), its safety and reliability are the most important factors to the safety operation of NPP. Software V&V (verification and validation) is a significant method to ensure the safety and reliability of the nuclear power safety I&C (instruments and control) system software, the system to evaluate the efficient of V&V activities needs to further research. An evaluation model of V&V activities has been described in the paper. The anomaly density, V&V effectiveness and V&V efficiency which are to measure the V&V effort, have been included in the model. In the article, the critical point of the anomaly density, V&V effectiveness, and V&V efficiency have been analyzed. Based on the V&V results of nuclear power safety I&C system software, a practice case has been performed to evaluate the V&V activities.
