Eddy Current Testing of Zircaloy Wires

Abstract

Fuel bundles for Rajasthan Atomic Power Reactor, consist of a cluster of 19 elements held together by zir-caloy and plates and spaced by wire helices on the six elements of the inner ring and alternative elements of the outer ring. As in the case of all other reactor mater-ials, the zircaloy wire also need be inspected 100% to avoid any defective part entering the reactor system. The zircaloy wire must be free from defects such as seams, internal voids, welded spots etc apart from the dimensio-nal and metallurgical requirements.
