核电厂安全级软件工具鉴定

Identification of safety level software tools for nuclear power plant

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。

Tool used in design and verification and validation is necessary in safety system of nuclear power plant(NPP).Then the reliability and rationality of tool are important,affecting the reliability of final products.So,in this article,the requirements of standards used in instrumentation and control systems of NPP are discussed,and emphasizing the demands of tool qualification. The methods and flow of software tool qualification in safety system of NPP are concluded, by analysising the standards requirements.This gives references for suppliers and users of software tool used in safety system of NPP.
