摘要

The life cycle of software can be divided into the concept, requirements, design, construction and integration phase and so on. The risk analysis and management should been executed during the software life cycle. The risks of the instrumentation and control (I&C) system include the technical and management risks. The concern of risk analysis is different in the software life cycle. The verification and validation (V&V) effort may identify the technical and management risks that have a measureable possibility of negative consequences to I&C system in nuclear power plants (NPPs). The risk analysis is one of the minimum tasks of the software verification and validation. The IEEE 1012-2017 Annex J has described the risk analysis, risk estimation and risk evaluation in general. The risks of the software V&V activities will be identified in this paper. Based on the risks of the software V&V activities, the risk management strategy has been proposed.
