Abstract
Thin-walled nickel tubes are used for fabrication of cover gas hydrogen sensors of fast breeder reactors. Eddy current non-destructive testing of these thin-walled nickel tubes poses difficulties due to the high magnetic permeability of nickel and non-availability of proper standards for testing tubes with diameter and wall thickness less than 3.0 mm and 0.9 mm, respectively. In this work, a saturation-based eddy current procedure has been developed for the quality control of nickel tubes of 2.5 mm outer diameter and 0.25 mm wall thickness. This procedure has reliably detected small dents as shallow as 0.1 mm deep on the outer surface as also verified by visual examination.
