STARS ENCLOSURE 1

Diablo Canyon Nuclear Power Plant, Units 1 and 2 License Renewal Application Request for Additional Information Aging Management Programs 82.1.18-2 (follow-up)

In its November 24, 2010, response to RAI B2.1.18-2 (follow-up), the applicant provided additional details on the Buried Piping and Tanks Inspection Program.

Discussion:

The staff was unclear of the inspection details of the in-scope buried copper valves in the makeup water system. In addition, the staff was not clear of the actual length of steel piping in the makeup water system that is buried. The staff was concerned that the applicant's commitment appeared to allow for non-destructive examinations instead of visual examinations.

The applicant agreed to supplement its response to RAI B2.1.18-2 (follow-up) to address the staff's concerns.
