- 194 - AN ADVANCED HEAT EXCHANGER EDDY CURRENT INSPECTION SYSTEM M. Ve.Ve.Mno, H. Ghznt, H. Licht Atomic Energy oß Canada Limi.te.cl Chalk Rivz/i, Ontario ABSTRACT Heat exchangers are important components in many process industries, especially nuclear power plants. Nondestructive testing techniques and equipment are required for fast, reliable testing of heat exchanger tubes during both unanticipated and scheduled inspections. An advanced eddy current inspection system has been developed at Chalk River Nuclear Laboratories to meet this need. This system was designed to meet the needs of the operator, analyst, station manager and regulatory agencies. The inspection system provides real-time data acquisition, display, recording and hardcopying to allow on-line analysis by a qualified eddy current analyst. In real time, a one page printout containing impedance images and strip chart traces of eddy current signals is produced for each tube. Tube coordinates, inspection data, print number and data acquisition validity messages are also included for record keeping purposes. This record enables the signal analyst to readily identify, analyze and comment on anomalous signals. Three pairs of eddy current test data (X and Y components) can be fed into the system. All three data sets plus probe position and tube information are stored on FM tape. The operator can select one data set for real-time display. A sophisticated tape playback feature permits a convenient means of further analyzing data. The real-time hardcopying allows the inspection team to provide the utility manager with a copy of the data and inspection results immediately following the inspection. This inspection system, known as R'Eddy Record, requires two people to operate, can realistically inspect 400 tubes/8 h shift, and is compatible with all commercially available single and multifrequency eddy current instruments using either absolute or differential type probes. A particularly impressive feature of the format used to present the data is the inherent ability of comparing previous inspection data with current inspection data. This provides a convenient means of monitoring a heat exchanger's tube performance, and permits long range planning for tube plugging and/or heat exchanger replacement. This paper describes the complete inspection system, how it is operated and field experience to date.
