Abstract
Nuclear reactor fuel rod leakage is determined by measurement of vibrational characteristics of a resilient, flexible means sealed within the upper end caps of the fuel elements. The flexible means, which is preferably a metallic diaphragm, is set into motion and the vibration measurements are made by a special tool which fits over the end cap of the fuel element to be tested.
