SUMMARY

OF SEPTEMBER 25, 1990 PUBLIC MEETING ON INSTALLATION OF SCHEDULE AND DEDICATION OF SIXTH DIESEL GENERATOR AT DIABLO CANYON On September 25, 1990 the NRC staff met with the Pacific Gas and Electric Company (PG&E or the licensee) in Rockvi lie, Maryland to discuss the above subjects.

Attendees at the meeting are given in Enclosure 1.

Viewgraphs presented by PG&E at the meeting are given in Enclosure 2.

At the meeting PG&E discussed the schedule for installation, testing, and final tie-in of the sixth diesel, and the basis for the schedule.

Also discussed were some aspects of the dedication process for the diesel generator.

At the conclusion of the the meeting, the licensee indicated that it would be prepared to discuss the dedication program in more detai 1 in about two months, and that a meeting for that purpose could be arranged.
