UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 May 14, 1991 Docket Nos. 50-269, 50-270 and 50-287 Mr. M.S. Tuckman, Vice President Nuclear Operations Duke Power Company P.O. Box 1007 Charlotte, North Carolina 28201-1007
Dear Mr. Tuckman:
SUBJECT:
INSERVICE INSPECTION PROGRAM FOR SECOND TEN-YEAR INTERVAL OCONEE NUCLEAR STATION, UNITS 1, 2 AND 3 (TACS 57036/57037/57038)
The NRC has completed its review of the inservice inspection (ISI) program for the second ten years of operation of the Oconee Nuclear Station, Units 1, 2 and 3. The review was based upon changes to your ISI program through Revision 5, dated July 5, 1988. Our Safety Evaluation is enclosed (Enclosure 1).
Our safety review has been performed with the technical assistance of a contractor, Science Applications International Corporation (SAIC), and our enclosed evaluation incorporates SAIC's Technical Evaluation Report (TER), Enclosure 2. We endorse SAIC's TER, including its findings.
During the course of this review, we have determined that certain requirements of Section XI of the ASME Code for which you have requested relief are either impractical or unnecessary to perform at the Oconee Nuclear Station, and the alternate examinations specified in your submittals ensure an acceptable level of structural integrity of the subject components. The alternate methods of examination are acceptable as discussed in the TER and are imposed in lieu of the applicable Code requirements. For these requirements, relief from the Code requirements is granted as requested, or with conditions as specified in Table 1 of Enclosure 1, pursuant to 10 CFR 50.55a(a)(3)i, 50.55a(a)(3)ii, and 50.55a(g)(6)(i). The specific section is identified in Table 1. This relief is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest given due consideration to the burden that could result if the requirements were imposed on your facility.
In the case of eight requests for relief, we have determined either that relief was not required or that a finding that the requirements were either impractical or unnecessary could not be made. In each of these cases, we have denied the requests.
We have determined that the Oconee ISI program reflects compliance with Commission requirements and with ASME Code,Section XI, except as relief has been granted, or granted with alternative requirements. On this basis, we conclude that
M.S. Tuckman 2 -
May 14, 1991 Revision 5 of the Oconee Nuclear Station, Units 1, 2 and 3, Second Ten-Year Interval Inservice Inspection Program with related additional information and authorized reliefs, constitute part of the basis for meeting the requirements of 10 CFR 50.55a and the Technical Specifications.
If you have questions regarding this matter, contact Len Wiens at (301) 492-0906.
This completes our efforts on TACS 57036/57037/57038.
