METHOD FOR DETECTING CORE FLOW BLOCKAGE OF LIQUID METAL REACTOR USING TEMPERATURE FLUCTUATION AND APPARATUS THEREOF

摘要

A method and an apparatus for detecting core flow blockage of a liquid metal reactor using temperature fluctuation are provided to improve stability of the liquid metal reactor and to facilitate repair by detecting the core flow blockage during a normal operation. A method for detecting core flow blockage of a liquid metal reactor using temperature fluctuation includes the steps of: measuring a temperature of a core upper part(S3010); analyzing the measured temperature fluctuation(S3020); and determining a location and a size of the flow blockage according to the result of analysis regarding the temperature fluctuation(S3030).
