November 25, 1998 Mr. William R. McCollum, Jr.
Vice President, Oconee Nuclear Site Duke Energy Corporation P. 0. Box 1439 Seneca, SC 29679
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3, LICENSE RENEWAL APPLICATION
Dear Mr. McCollum:
By letter dated July 6, 1998, Duke Energy Corporation (Duke) submitted for the Nuclear Regulatory Commission's (NRC's) review an application pursuant to 10 CFR Part 54, to renew the operating licenses for the Oconee Nuclear Station (Oconee), Units 1, 2, and 3. Exhibit A to the application is the Oconee Nuclear Station License Renewal Technical Information Report (OLRP-1001), which contains the technical information required by 10 CFR Part 54. The NRC staff is reviewing the information contained in OLRP-1001 and has identified, in the enclosure, areas where additional information is needed to complete its review. Specifically, the enclosed questions are from the Civil Engineering and Geosciences Branch regarding OLRP-1001 Section 3.2.
Please provide a schedule by letter, electronic mail, or telephonically for the submittal of your responses within 30 days of the receipt of this letter. Additionally, the staff would be willing to meet with Duke prior to the submittal of the responses to provide clarifications of the staff's requests for additional information.
Sincerely, M
Stephen T. Hoffman, Senior Project Manager.

3.2 Description of the Process to Identify Applicable Aging Effects 3.2-2 Oconee operating experience has indicated that certain portions of the structures and structural components are subjected to moisture/water exposure on a sustained basis, whether from natural sources (such as ground and river water) or operating conditions (system leakages), that have resulted in material degradation. Provide justification as to why moisture/water (Section 3.2.2.3) should not be considered an applicable aging effect that would warrant an aging management review for the structures and structural components subjected to this environment. Event driven corrective actions do not appear to be an aging management process sufficient to address this issue in a comprehensive manner for the extended period of operation.
3.2-3 Table 3.2-2 provides assessments of structures for 40 year and 60 year radiation exposure in terms of the integrated doses in 'rads.' However, the important parameters affecting the structural properties are high-flux neutrons and integrated gamma doses.
Provide the Table in terms of these parameters. For the reactor cavities, the steam generator cavities, and the spent fuel pools (Auxiliary Buildings) provide an assessment of synergistic effects of temperatures and radiation on the structural properties of the structures and components (e.g., concrete walls, concrete reactor supports, steel supports, and anchor bolts) and address as such as part of the aging management programs in these areas.
