Multifrequency eddy current system for steam generator tubing inspection. Volume 1: Progress Summary. Interim report

Description

A multifrequency eddy current testing system has been developed to test nuclear steam generator tubes and has been evaluated on a steam generator mockup. Results to date show that use of more than one inspection frequency facilitates electronic assessment of flaw depth, thereby reducing reliance on visual interpretation of signal information by operators. This interim report on Research Project 403 consists of two volumes. Volume I, Progress Summary, provides details on the system design and an evaluation of the system's performance on a steam generator mockup. The system consists of a four frequency signal generator, which excites the inspection coil, followed by a Walsh function instrument which extracts information from any two of the four frequencies present in the composite test signal
