Abstract

PURPOSE: This failure fuel detecting method samples a cooling material after covering a fuel aggregate upper part by a cap and feeding gas, improving the detecting accuracy of failure fuel by deciding cooling material sampling time at a time when cooling material temperature becomes to a setting value.
