A Brief Analysis on Nuclear Instrument System Interface and Periodic Test Framework of Nuclear Power Plant

In order to optimize the interface and periodic test framework of the nuclear instrument system of nuclear power plant, this study compares and analyzes the difference between four kinds of interface and periodic test framework used by Rolls-Royce based on Spinline3 platform and AREVA based on TXS platform in different nuclear power plants, which are mainly used in the nuclear instrument system of PWR nuclear power plants in China. The analysis results show that using the interface of analog output and built-in signal source, and collecting feedback from downstream system, can avoid information inconsistency and improve the reliability of the equipment. The interface and periodic test framework proposed in this study can be used as a reference for the design of new nuclear power plants.
