Abstract
Since the digital technology was used in the safety digital I&C (Instrument and Control) system of nuclear power plant (NPP), its safety and reliability have been one of the most important factors to the safety operation of NPP. V&V activity is a significant method to insure the safety and reliability of the nuclear power I&C system software, the system to evaluate the efficient of V&V activity need further research. This paper on the basis of CPR1000 NPP Reactor Protection System (RPS) software development project, use the concept V&V activity for example, make a discussion for the evaluation of V&V activity, including the description of general tasks, definition of the Failure Modes, and analysis of V&V activity by FMEA (Failure Modes Effects Analysis). The results of our evaluation method in project show that the efficiency of V&V activities has been improved, and provide references for the evaluation to other NPP I&C system software development V&V activity.
