SUMMARY
OF JULY 28, 1989 MEETING ON DESIGN BASIS DOCUMENTATION PROGRAM On July 28, 1989, representatives of Duke Power Company (DPC) made a presentation to the NRC staff on the DPC Nuclear Plant Design Basis Documentation (DBD) program. The meeting was held at DPC's request. The DPC presentation described the historical background leading to the development of the program, the actual program development, program project management, and a problem resolution process.
A discussion was held on the appropriate method of reporting deficiencies and subsequent corrective actions resulting from the DBD program. It was agreed that a separate Licensee Event Report (LER) would be submitted for each reportable event resulting from the DBD with a single LER supplement submitted at the completion of the DBD covering the final resolution of each of the LER's. DPC agreed to submit details of this process to the NRC for review.
Meeting attendees are listed in Enclosure 1. Handouts distributed by DPC during the presentation are provided in Enclosure 2.

System Design Bases/Objectives Design Basis:
The VG system shall supply control air at sufficient pressure to keep the emergency diesel generator running (Reference section 20.1.2 of specification no. MCS-1609.VG-00-0001).
Objective:
Verify that a control air pressure of no less than 90 psig and no greater than 135 psig is maintained, after the diesel starts, while the emergency diesel generator is running for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (Tech. Spec. 4.8.1.1.2e(8)). The starting air compressors shall be available to start during this test.
Test Frequency:
The control air test shall be performed with the same frequency as the emergency diesel start test.
Operability:
If a diesel fails this test, then it shall be declared inoperable.
