SUMMARY
OF JULY 13, 1989 MEETING AT OCONEE ON SELF-INITIATED TECHNICAL AUDIT On July 13, 1989, NRC staff members met with representatives of Duke Power Company (DPC) comprising a Self-Initiated Technical Audit (SITA) team. The purpose of the meeting was to discuss in detail the SITA process as it was being applied to the Oconee emergency power distribution system.
DPC made a brief presentation of the SITA process and introduced the SITA team members.
The remainder of the meeting was comprised of questions and answers between the NRC and the SITA team.
As presented by the DPC representatives, the SITA process will perform an indepth engineering review of a vertical slice of the emergency electrical system.
The review will encompass the system design, Technical Specifications, operating procedures, administrative procedures, preventative maintenance, surveillances and operator training. When reviewing various areas, the SITA team is to evaluate both whether the requirements are being met and if the requirements are appropriate. The SITA process will review to a level that will ensure the system can adequately perform its design function, and will include support and auxiliary systems as necessary, including those at the Keowee Station. If a weakness is found in a component or subsystem, other similar components or subsystems will be reviewed to determine if a generic problem exits. The present SITA was recently started and no major design weaknesses have been found to date.
It was also stated that a Design Basis Documentation (DBD) program is being conducted on the Oconee emergency electrical system concurrently with the SITA.
Any technical attributes of the SITA which could be affected by changes in the DBD will be revisited by the SITA team. A formal report of the SITA will be prepared.
After the meeting with the SITA team concluded, the NRC staff members toured the Keowee hydrostation.
