NPF-7 VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNIT 2 REQUEST FOR ADDITIONAL INFORMATION ASME SECTION Xi INSERVICE INSPECTION PROGRAM RELIEF REQUEST CMP-020 EXAMINATION OF REACTOR PRESSURE VESSEL HEAD-TO-FLANGE WELD In a January 28, 2003 letter (Serial No.03-050), Virginia Electric and Power Company (Dominion) submitted a request for relief from certain requirements of ASME Section Xi.
Specifically, the preservice examinations for the North Anna Unit 2 replacement head were conducted to the requirements of the 1995 Edition through 1996 Addenda of ASME Section Xl. However, interferences due to lifting lugs and the weld configuration prohibited complete examination of the reactor pressure vessel head-to-flange weld.
During an April 21, 2003 telephone conference call, the NRC staff requested additional information regarding the examination interferences and the inservice inspection interval dates for Unit 2 to complete the review of the proposed relief request. The requested information is provided below and in Attachment 1 of this letter.
North Anna Unit 2 is currently in the third Inservice Inspection Interval that started December 14, 2001 and is scheduled to end December 13, 2010.
The reactor vessel head (RVH) fabrication drawings provided in Attachment 1 are North Anna Unit 1 drawings.
These drawings are typical of the RVHs fabricated by Framatome for North Anna Units 1 and 2 and the Surry Unit 1 replacement heads and provide the details of the examination interferences.
Framatome ANP considers information on the RVH drawings as proprietary. To conform to the requirements of 10 CFR 2.790 conceming the protection of proprietary information, the proprietary information in Attachment 1 is contained within brackets. A non-proprietary redacted version of Attachment 1 is also provided in Attachment 2. Where the proprietary information has been deleted in the non-proprietary version, only the brackets remain.
Framatome ANP's basis for classifying the information proprietary pursuant to 10 CFR 2.790(b)(1) is included in the affidavit included in Attachment 3.
Accordingly, it is requested that the information that is proprietary to Framatome ANP in Attachment 1 be 8 0 41
.withheld from public disclosure in accordance with 10 CFR 2.790 of the Commission's regulations.
If you have any additional questions conceming this request, please contact Mr.
Thomas Shaub at (804) 273-2763.
Very truly yours, Leslie N. Hart Vice President - Nuclear Engineering Attachments
