C-B SGN 23R- 2 CR-IP2-2006-02723 - Found a recordable indication. The indication is YES subsurface, not connected to the Inside Diameter (ID)and has Ultrasonic Testing (UT) characteristics consistent with fabrication anomoly. The UT examination results were compared to the preservice radiographic inspection report (and verified on the film) which showed porosity and slag inclusions in the area of the indication. The indication is not service induced. Based on the crack growth evaluation the as found indication meets ASME Section XI Code, 1989 Edition No Addenda flaw acceptance criteria and is acceptable for the duration of plant life. No repair is necessary.

C-F-1 Weld 16 - 193 CR-IP2-2006-01962 - A subsurface indication was found. The weld was YES then ground-flush to allow for sizing of the indication. The indication is not connected to the IDand was characterized and sized as a subsurface indication and found to be acceptable for continued service inaccordance with ASME Section XI Code, 1989 Edition No Addenda.

No further actions are required.
