Pulsed Eddy Current Defectoscopy of Irradiated WWER Fuel Rods
- 1. JSC 'SSC RIAR' Dimitrovgrad (Russian Federation)
Description
Defectoscopy of irradiated WWER fuel rods in the RIAR hot cells is performed by means of pulsed eddy current method. Uniformity defects, local geometry anomalies can be formed during the operation of fuel rods. For failed fuel rods, appearance of secondary defects related to water ingress, oxidation and hydrogenation of ZR alloy cladding is typical. The defectoscope consists of two modules built in the industrial computer-pulse generator and analog-to-digital converter (ADC). To reveal and identify anomalies, A-, D-scans, envelope curves and hodograph curves of pulse signal are used. The EC-method makes it possible to reveal damaged fuel rods in failed WWER fuel assemblies (FAs), determine location and identify primary through defects and secondary anomalies. Totally 49 WWER FAs, including 18 failed FAs, were examined by means of this method. (author)
