CGIEGQBY CQtOIIION B-G-2. One Steam Generator Primary Manway Stud was rejected visually due to excessive galling in the shaft area. This galling was a result of improper extraction.
B-P One 1" socket meld was found to be leaking during the Reactor Coolant System Leak Test. The weld was in the Reactor Coolant Pump Sealmater Injection System.
B-G Steam Generator Tubing Defects:
GEN _1 GEN _E GEN _3 Indications:
> 40% 3 19 11 20-40% 3 26 13
< 20% 2 22 17 The tube wall degradation was detected in 3 key areas: the center vertical support strap, the region associated with a sludge pile, and the steam blanketed region postulated to exist at U-bends in rows 5 thru 8. The defect indications at the vertical straps and tight U-bends are characteristic of a corrosion phenomenon. This is consistant with the suspected presence of dry-boiling and a resultant concentration of causative contaminants in the effective regions. Pitting type indications were observed immediately above, at the top, and below a classical sludge pile surface contour associated with a PWR steam generator.
No recordable defects were found during the remaining examinations.

B-P The leaking weld found during the RCS Leak Test was isolated, ground out in area of defect, and rewelded. A liquid penetrant exam was performed after grinding to ensure that the entire defect was removed. A final liquid penetrant exam and leak test was performed to verify the integrity of the weld.
B-G In Steam Generator 1, the 3 tubes which were found to have indications greater than 40% through wall were plugged.
In Steam Generator 2, the 19 tubes which were found to have indications greater than 40% through wall plus 3 others were plugged.
^
In Steam Generator 3, the 11 tubes which were found to have indications greater than 40% tnrough wall were plugged.
Al1~ plugs were rolled in place.
