LEAKAGE DETECTION SYSTEM AND LEAKAGE DETECTION METHOD

A leakage detection system (1) detects leakage of sodium in an air cooler (210) in a decay heat removal system for removing decay heat generated in a reactor internal by using sodium as a coolant. The leakage detection system (1) includes a camera (2) that detects at least one of a sodium droplet an...

Zusammenfassung:A leakage detection system (1) detects leakage of sodium in an air cooler (210) in a decay heat removal system for removing decay heat generated in a reactor internal by using sodium as a coolant. The leakage detection system (1) includes a camera (2) that detects at least one of a sodium droplet and sodium aerosol in a flow path of air in the air cooler (210), a measurement device (3) that measures concentration of sodium in the air at a downstream side of the camera (2), and a determination unit (43) that determines detection of leakage of sodium based on a detection result of the camera (2) and a measurement result of the measurement device (3).
