核安全级应用软件V&V过程体系建设及实践

Software Verification and Validation of Safety DCS System

依据我国核安全法规要求,在核安全级应用软件开发过程中,应通过进行一系列的验证与确认(V&V)活动来证明其正确性和安全性。通过对法规标准的研究,结合工程应用经验,明晰V&V管理、工作流程、技术文件和V&V工具4个方面的V&V要求和方法,提出一套适用于核电站安全级DCS应用软件的V&V体系。该体系已经应用在某核电站项目中,保证了软件的质量和项目的成功实施。该体系在后续的华龙一号、AP1000等先进堆型项目中也具有较好的应用前景。

According to the nuclear safety regulations, verification and validation （V＆V） activities should be carded out during the software development process. Based on the research of the regulations and standards and engineering experience, a suitable safety class DCS application software V＆V system is established. This V＆V system has been used in a nuclear power plant project, to ensure the quality of the software and the successful implementation of the project. The system also has good prospects in the follow-up projects, such as HRR1000 and AP1000 advanced reactors.
