Abstract

The present invention relates to a hybrid reactor in-core detector assembly for core monitoring and protection and, specifically, a hybrid reactor in-core detector assembly for simultaneously carrying out a reactor core monitoring function and a reactor core protection function, comprising: vanadium detectors and a background detector for carrying out the reactor core monitoring function; platinum detectors for carrying out the reactor core protection function; and one integrated core exit thermocouple. According to the present invention, since the reactor in-core detector assembly using the vanadium detectors and the platinum detectors is a hybrid type, the reactor core monitoring function and the reactor core protection function can be simultaneously carried out.

Description

technical field [0001] The present invention relates to an in-core detector assembly, and more particularly, to a hybrid in-core detector assembly capable of simultaneously performing core monitoring and core protection functions. Background technique [0002] The most important index for safe operation of a nuclear reactor is the power crest factor, and in order to monitor the value of the power crest factor, it is necessary to continuously and accurately measure the three-dimensional core power distribution. In-core detectors for performing core monitoring of a nuclear power plant are classified into a mobile type (for a WH type nuclear power plant) and a fixed type (for an OPR1000 nuclear power plant). [0003] The mobile in-core detector can accurately measure the three-dimensional core power distribution, but cannot perform on-line measurement because the power distribution is only measured periodically. On the other hand, fixed in-core detectors are capable of perform...
