Abstract
With the popularity of digital electronic instruments, more and more attention is paid to the safety-related software quality. RPN (nuclear instrumentation system) is a class 1E protection system. RPN is designed to provide a snapshot of neutron activity within the reactor core. RPN provides the snapshot throughout all operational phases, from start-up to full power and post-accident situations. In order to verify the reliability of the software of the digital RPN, the software verification and validation activities are carried out, according to HAD102/16-2004 and IEC60880-2006. The activities include compiling software verification and validation plan, determining the software lifecycle model, verifying the system specification, verifying software requirement, verifying software design, analying code rule, carrying out software unit test, carrying out software integration test and carrying out validation test. These works show that the reliability of the software of the RPN meets the requirements of HAD102/16-2004 and IEC60880-2006, and the performance meets the requirements of the technical specifications.
