DRAFT - 07/31/2002 United States Nuclear Regulatory Commission Serial No.:
02-472 Attention: Document Control Desk LR/DEA:
R0 Washington, DC 20555-0001 Docket Nos.:
50-280/281 50-338/339 License Nos.: DPR-32/37 NPF-4/7 Gentlemen:
VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION)
SURRY AND NORTH ANNA POWER STATIONS UNITS 1 AND 2 LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION In an October 22, 2001 letter, the NRC requested additional information associated with Section 2.1 of the license renewal applications (LRAs) for Surry and North Anna Power Stations. Dominions letter dated February 1, 2002 (Serial No. 01-686A) provided the requested response. Supplemental information was also provided by letter dated May 22, 2002 (Serial No.02-163). During conversations with the NRC on July 25, 2002, the staff requested additional details of information previously provided in response to Request for Additional Information (RAI) 2.1-3. The attachment to this letter contains the requested supplemental details.
Should you have any questions regarding this submittal, please contact Mr. J. E.
Wroniewicz at (804) 273-2186.
Very truly yours, Leslie N. Hartz Vice President - Nuclear Engineering Attachment Commitments made in this letter: None

Docket Nos. 50-280/281 50-38/339 Serial No.: 02-472 Attachment Page 2 of 12 DRAFT - 07/31/2002 Supplemental Response to RAI 2.1-3:
By letter dated October 22, 2001, the NRC staff requested additional information regarding Criterion 2 systems, structures, and components (SSCs) as defined in 10 CFR 54.4(a)(2). Dominion responded to these requests in letters dated February 1, 2002 (Serial N. 01-686A) and May 22, 2002 (Serial No.02-163). These previous submittals (in response to RAI 2.1-3, particularly) identified several plant systems at both Surry and North Anna that were added to the license renewal (LR) scope as a result of the re-evaluation of the 10 CFR Part 54 Criterion 2 requirements. The RAI responses also identified systems already in the scope of LR whose evaluation boundaries were expanded as a result of the revised Criterion 2 screening requirements.
In addition to identifying systems associated with the expanded LR scope, the previous responses also identified the credited aging management activities (AMAs) for each applicable material group, environment, and aging effects combinations for each of the identified systems. This information was provided on a system basis and was not broken down into the component groups as was done in the Aging Management Review (AMR) Results tables included in Section 3 of the License Renewal Applications (LRAs). No new material/environment combinations or aging management activities were identified as a result of the added scope.
The staff subsequently requested that Dominion provide the same level of detail that was provided in the LRA AMR Results tables for each of the additional systems (added as a result of the Criterion 2 expanded scope). That additional detail is provided with this response.
Each table provided in this response has an identifying number which begins with either an S or an N indicating its applicability to Surry or North Anna, respectively. These new tables have a number sequence that would be appropriate if they were being inserted into the existing LRAs as additional AMR Results tables. The intended functions are abbreviated as LSI, Limited Structural Integrity, as defined in the previous RAI response, and PB, Pressure Boundary.
