ABSTRACT:
Apparatus and a method for the inspection of tubes in a steam generator include a film-bearing cassette probe insertable into a target tube to a predetermined region to be inspected and a source of radiation, preferably a radioisotope, insertable into a tube adjacent said target tube to a position therealong laterally adjacent the region to be inspected on said target tube. The cassette probe is sufficiently flexible to transit regions of tight tube curvature.
