Research on the Verification and Validation Method of Safety Analysis Software in Nuclear Power Plants

With the wide application of software in nuclear power plants design and control process, the regulatory has strengthened its supervision. At this moment, the software used for safety analysis of nuclear power plants design also needs to carry out strict qualification work, which is the first time that the qualification of safety analysis software is required in China. How to carry out the qualification work to ensure the correctness of self-developed safety analysis software has become an urgent problem to be solved. Base on the interpretation of the regulatory requirements for safety analysis software, compare with the analysis of software verification and validation (V&V) requirements in IEEE 1012, a method for safety analysis software qualification has been pointed out in this paper. This method draws on the successful experience of nuclear power plant safety-level software V&V, provides a complete V&V process and clear V&V tasks, and characterizes by easy to execution.
