CONVERGENCE REACTOR IN-CORE DETECTOR ASSEMBLY FOR CORE MONITORING AND PROTECTION

摘要

The present invention relates to a convergence reactor in-core detector assembly for core monitoring and protection, which is a convergence reactor in-core detector assembly for simultaneously carrying out a reactor core monitoring function and a reactor core protection function, comprising: five vanadium detectors and one background detector for carrying out the reactor core monitoring function; three platinum detectors which are arranged to overlap each other so as to respectively use three input algorithms of an upper, middle and lower ex-core detector for carrying out the reactor core protection function; and one integrated core exit thermocouple. According to the present invention, the reactor core monitoring function and the reactor core protection function can be simultaneously carried out by using the vanadium detectors and the platinum detectors.
