Patent
·
OSTI ID:7185090
The 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 the target tube to a position laterally adjacent the region to be inspected on the target tube. The cassette probe is sufficiently flexible to transit regions of tight tube curvature. 8 claims, 12 drawing figures.
