Research of Test Scheme of Verification and Validation of Reactor Protection System Based on TXS Platform

Based on IEC60880 standard for software used in nuclear power plant safety systems, the test scheme of verification and validation（V＆V） test for reactor protection system（RPS） of Ling’ao nuclear power plant（NPP） based on safety digital TXS platform is introduced. Furthermore, the completeness and correctness of V＆V test is analyzed accordingly. The successful commercial operation of Ling’ao NPP fully proves the importance and necessity of RPS V＆V test, what is more important, the research provides good experiences and references for RPS V＆V test in future nuclear power plants based on other I＆C platform.
