A Study About Software Development QC and QA of the Digital RPS in Nuclear Power Plant

Reactor protection system (RPS) is one of the very important systems in nuclear power plant (NPP). Since the digital technology was used in RPS, for the software development,the quality control (QC) and quality assurance (QA) should be further researched. Based on the CPR1000 digital RPS software development project, this paper discusses the definitions and necessity for QC and QA, illustrates the software life cycle, proposes the practical verification and validation (V&V) activities, describes V&V process through in software development. In each stage of V&V process, the V&V activities that QC and QA works and products implemented by are detailed introduced, provides a practical and efficient reference of QC and QA method for other nuclear digital safety system software development projects.
