Abstract

In order to detect defective fuel rods in fuel elements of water cooled nuclear reactors, the fuel elements are firstly subjected to a hydrostatic alternating pressure treatment. The cladding tubes of the fuel rods are then heated in the vicinity of an accessible end cap, resulting in heating of the water situated in said end cap in the event of damage. The presence of water is established by measuring the temporal temperature characteristic at the end cap or by applying ultrasonic pulses to the end cap and evaluating the echo pulses.
