Goodwin, L E

A number of similar eddy current instruments were developed to measure the thickness of Zircaloy over U metal in the range of 5 to 25 mils, Zircaloy over UO/sub 2/ in the range of 20 to 40 mils, and the wall thickness of Zircaloy tubes in the range of 20 to 40 mils. The instruments were designed for use with hand-held probes or with feeder-mounted probes to measure the inside and outside cladding thickness of tubular elements and the wall thickness of Zircaloy sheaths. The instruments have a sensitivity of 3 microamps per mil change in Zircaloy thickness and an accuracy of plus or minus 1 mil. (auth)
