A Study About Software VV Evaluation of Safety IC System in Nuclear Power Plant

摘要

Software verification and validation (V&V) is internationally recognized as an important technology to improve software reliability. The promulgation of new regulations and standards related to nuclear safety software may put forward new and higher requirements, so that existing software V&V technical solutions cannot fully cover the new requirements. There is still a gap between the new requirements of the new regulations, the new standards and the software V&V experience feedback on issues of Generic Design Assessment (GDA) of Office for Nuclear Regulation (ONR). Therefore, relevant research of software V&V is needed so as to meet the new requirements for domestic and international safety reviews. Based on the comparative analysis of the new and old nuclear safety standards, such as Institute of Electrical and Electronic Engineers (IEEE) 1012 and International Atomic Energy Agency (IAEA) No. SSG-39 and ONR review principles, as well as the technical opinion report of European Union (EU) safety software certification, the main technical differences were sorted out to provide technical reference for the establishment of better applicability or the optimization of the nuclear safety I&C system software V&V solution.
