SEP 14 993 Docket Nos. 50-269, 50-270, 50-287 License Nos. DRP-38, DRP-47, DRP-55 Duke Power Company ATTN: Mr. J. W. Hampton Vice President, Oconee Site P. 0. Box 1439 Seneca, SC 29679 Gentlemen,
SUBJECT:
SERVICE WATER SYSTEM OPERATIONAL PERFORMANCE INSPECTION OCONEE NUCLEAR STATION REPORT NOS. 50-269/93-25, 50-270/93-25, AND 50-287/93-25 This is to advise you of a special inspection initiative that is being performed at operating reactors. It will include an inspection at your Oconee site. The initiative is entitled the "Service Water System Operational Performance Inspection (SWSOPI)."
The purpose of the inspection is to systematically evaluate the performance of the service 'water system. Inclusive in the inspection, will be a comprehensive review of system design, maintenance, operation, and testing.
The inspection will verify the status of your initiatives associated with Generic Letter 89-13, "Service Water System Problems Affecting Safety Related Equipment."
In addition, the inspection will encompass an evaluation of your engineering and technical support activities as they relate to the service water system.
This is a-team inspection with up to seven individuals expected to be involved; one team leader and six subject matter experts. Somewhere during the first week in November, the team will visit your site to accomplish preliminary inspection activities. The entire team will be onsite the weeks of November 15-19 and November 29-December 3, 1993.
To improve the effectiveness of the inspection and lessen its impact upon your staff, there are a number of actions the team is, requesting. First, since overview presentations have been an efficient means to communicate relevant information, informal presentations from your staff during the week of November 1st, describing the multiple service water systems (design and operations), significant service water modifications since original licensing, actions in response to Generic Letter 89-13, and a history of system problems are encouraged. Second, a tour/walkdown of the service water systems during the week of November 1st by the cognizant system and design engineer would be appreciated. Third, the team will be reviewing a large amount of records, procedures, and design documents. Therefore, a request for information is provided as an enclosure to this letter. There are two categories of information. The first is information needed by October 18th. The second is information to be available and/or easily retrievable when the team is onsite.

SEP 14 I993 The team leader for this inspection will be Mr. W. G. Rogers from Region II.
Mr. Rogers will contact members of your staff in the near future to discuss the details of the inspection.
If you have any questions in the interim regarding the inspection program, we will be pleased to discuss them with you.
Sincerely,
