核电厂安全级仪控设备的研发和验证与确认必然会引入工具,因而工具的可靠性和合理性会直接影响最终产品的可靠性。本文论述了核电厂仪控系统标准在工具应用方面的要求,重点论述了工具鉴定的要求。通过对国际通用标准的分析研究,总结出核电厂安全级软件工具鉴定的方法和流程,为核电厂安全级软件工具供货商和应用商提供参考。
R & D and validation and verification of safety instrumentation at nuclear power plants will inevitably introduce tools, so the reliability and rationality of the tools will directly affect the reliability of the final product. This article discusses the requirements of instrumentation system standards for nuclear power plant applications and focuses on the requirements of tool qualification. Through the analysis of international common standards, this paper summarizes the methods and procedures for the appraisal of safety-level software tools in nuclear power plants and provides reference for suppliers and applicants of safety-level software tools for nuclear power plants.
