By e-mail dated July 22, 2010, the staff sent D-RAIs to PG&E regarding scoping and screening and aging management review.

Enclosure 2 Diablo Canyon Nuclear Power Plant, Units 1 and 2 License Renewal Application Draft Request for Additional Information Scoping and Screening/Aging Management Review D-RAI 2.3.3.4-01

On LRA drawings LR-DCPP-14-106714-03 and LR-DCPP-14-107714-03, the applicant depicts the label "stuffing box" at locations 31-C, 33-C, and 35-C, but the components are not shown.

On the LRA AMR Table 2.3.3-4 for the component cooling water (CCW) system, the "stuffing box" component is not listed. The staff requests that the applicant justify the exclusion of the stuffing box from LRA Table 2.3.3-4.

Discussion

Based on discussion with the applicant, it was determined that the stuffing box for the pumps were within the scope of license renewal and covered within the pump component type in LRA Table 2.3.3-4. Therefore, this question is withdrawn and will not be sent as a formal RAI.
