This 90-Day Special Report is submitted in accordance with Technical Specification (TS) 5.7.2.c. As required by TS 5.7.2.c, the report includes:

1. Number and extent of tubes inspected,
2. Location and percent of wall thickness penetration for each indication of an imperfection, j
3. Location, bobbin coil amplitude, and axial and circumferential extent (if determined) for each first span IGA indication, and ,

4. Identification of tubes plugged and sleeved.

l Reference A (TS notifications prior to ascension into MODE 4) reported the number of tubes plugged in the "A" 0TSG to be 26 tubes.

10R plugging list. '
