Nondestructive Examination of Irradiated Fuel Rods by Pulsed Eddy Current Techniques.

摘要

A number of fuel rods and unfueled zircaloy cladding tubes which had been irradiated in the Saxton reactor have undergone extensive nondestructive and corroborative destructive examinations by Aerojet Nuclear Company as part of the Water Reactor Safety Research Program,Irradiation Effects Test Series. This report discusses the pulsed eddy current (PEC) nondestructive examinations on the fuel rods and tubing and the metallography results on two fuel rods and one irradiated zircaloy tube. The PEC equipment,designed jointly by Argonne National Laboratory and Aerojet,performed very satisfactorily the functions of diameter,profile,and wall thickness measurements and OD and ID surface defect detection. The destructive examination provided reasonably good confirmation of ''defects''detected in the nondestructive examination. (ERA citation 01:012948)
