SUMMARY
OF MEETING WITH DUKE POWER COMPANY ON LICENSE RENEWAL ACTIVITIES FOR OCONEE NUCLEAR STATION UNITS 1, 2, AND 3 On July 17, 1997, representatives of Duke Power Company (Duke) met with the Nuclear Regulatory Commission staff to discuss Duke's technical review of mechanical components to support a potential license renewal application for Oconee Nuclear Station, Units 1, 2, and 3. A list of meeting attendees is provided in Attachment 1. The Duke handouts are contained in Attachments 2 and 3.
The meeting was requested by Duke to provide information on its integrated plant assessment (IPA) and time-limited aging analysis (TLAA) reviews for mechanical components that will be submitted as part of Duke's Oconee License Renewal Technical Information Topical Report, OLRP-1001. To demonstrate its evaluation process for mechanical components. Duke chose the standby shutdown facility fuel oil system to perform an IPA review and evaluated thermal fatigue as an example of a TLAA. Duke discussed Attachments 2 and 3 which describe their process and provides examples of documentation developed for system scoping, identification of system and component functions, component/commodity group listings, aging effects, and aging management reviews. Duke plans to submit complete examples by July 31, 1997, for staff review and to request staff feedback on the adequacy of the format and content of the information.provided.
The need for identifying in the application the evaluation boundaries for aging management reviews (AMRs) was discussed. Duke indicated that marked up drawings that are maintained onsite were used to identify the scope of mechanical systems subject to an AMR. The staff indicated that the application needs to clearly define the boundaries of the AMR in order for the staff to perform its review. Duke indicated that it will evaluate how to best describe the boundaries of the AMR in the application and may consider submitting marked up drawings.
Duke has previously submitted for staff review documents for the reactor building, electrical and instrumentation control components, and structures and structural components. After submittal of the mechanical components examples, the remaining topic for submittal is the reactor coolant system (RCS). Staff feedback was provided on the reactor building example in January 1997 and for the electrical and structural examples at a separate meeting on July 17, 1997. The staff questioned the need for submittal of an RCS example V NBCHLECENTIE COPY 9708040107 970730 PDR ADOCK 05000269
-2 requesting staff feedback on format and content. Duke agreed to evaluate the need for submittal of an RCS example.

> NRC Generic Communications search revealed GL 83-26, Clarification of Surveillance Requirements for Diesel Fuel Impurity Level Tests, which addresses fuel oil Impurity levels that may affect corrosion.
July 17, 1997 Oconee License Renewal Project 23 Mechanical IPA Example Carbon Steel Aging Effects Loss of material in carbon steel components is due to water and biological activity in the fuel oil and moist air entering the system through the tank vents Possible sources of water and biological activity in fuel oil are delivery tankers.
> Another source of water is condensation inside the storage tanks.
> Loss of material in carbon steel exposed to contaminated fuel oil and moist air is an applicable aging effect.
July 17, 1997 Oconee License Renewal Project 24
Mechanical IPA Example Stainless Steel Aging Effects
> Loss of material due to localized corrosion in stainless steel components may be caused by water and biological activity in the fuel oil.
> Possible sources of water and biological activity in fuel oil are delivery tankers.

TLAA Mechanical Example Thermal Fatigue (cont.)
Resolution of Fatigue issue:
> Historical data pertaining to actual system operation was compared to this assumption for all mechanical systems to determine thermal cycle values for all plant locations.
> O location within scopc was found to be susceptible to excessive thermal cycling.
> Piping and supports have been analyzed and modified to bring the pipe segments into Code compliance for 60 years.
