Abstract

PURPOSE: To provide an accurate detection of the leaked fuel by gradually suctioning entire coolant in the fuel assembly under a loaded condition of the reactor core, measuring a concentration of the radioactivity of the fission product and comparing the concentration of the radioactivity at the upper part of the fuel assembly.
