SUBJECT:

DAILY HIGHLIGHT - R. E. GINNA The ruptured tube in the Ginna steam generator was inspected in May 1981.

The ECT results showed that there was 20% penetration (an OD signal) 3 to 6 in, above the tubesheet. The failed tube is in row 42, column 55 which is near the periphery of steam generator.

It.is located in the " wedge area" of the steam generator. This is the section of the support plates that does not have flow holes. Three of the six previous small leaks that have been experienced have been in that area.

There is no sludge pile in that area.
