摘要

Nuclear power plant safety grade software performs important safety functions in nuclear power plants, and the consequences are very serious once the failure occurs. In order to ensure the safety and reliability of such software, software verification and validation of the entire life cycle is required in accordance with standards and regulations. Traceability analysis is an important method for software verification and validation. How to use this method correcdy in engineering practice is one of the difficulties of software V&V. In the industry, requirements are often split and itemized according to document chapters, and then traceability analysis is performed. This can lead to poor results in retrospective analysis and is time consuming and labor intensive. Based on the experience of engineering practice, this paper discusses in detail the advantages and disadvantages of different requirements items methods, the main points of traceability analysis, traceability analysis and other V&V tasks. Finally, the itemization method based on quality attribute is proposed, and the execution method and suggestion of traceability analysis are given, which provides a technical reference for the traceability analysis of the safety software of nuclear power plants.
