Description

The remote-field eddy current technique for inspecting non-magnetic, zirconium - 2% niobium-alloy pressure tubes, which are used in CANDU system nuclear reactors, has been developed in laboratory tests. Techniques used to optimize the operating performance of the remote field probe are described. Experimental results are presented showing excellent signal-to-noise for remote field scans detecting relatively small external tube wall surface defects. Sensitivity is enhanced by balancing the probe against an external reference signal. (author)
