SUMMARY
OF MEETING HELD ON SEPTEMBER 2, 1992, REGARDING INTEGRATED SCHEDULING PROGRAM This refers to the meeting conducted at the request of Carolina Power & Light Company (CP&L) at One White Flint North, Rockville, Maryland, on September 2, 1992. The purpose of the meeting was for CP&L to brief the NRC on the progress of their Integrated Scheduling Program (ISP).
A list of attendees and a copy of the CP&L handouts are enclosed (Enclosures 1 and 2).
This meeting is the third ISP meeting including the June 10, 1992, and July 29, 1992, ISP meetings with CP&L. During this meeting, CP&L discussed the prioritization process in the scheduling of projects within the scope of the ISP. The prioritization process will be applied to Level II ( NRC Commitment) and Level III (CP&L Initiatives) projects. Level I items (NRC Requirement),
projects with specific implementation dates in response to a rule, order or license condition, will not be scheduled with the ISP prioritization process.
For those other projects (Level II and Level III projects), the ISP will assign rankings through a Schedule Index. CP&L discussed the methodology and the use of probabilistic risk analysis data to generate the Schedule Index.
Following the meeting, CP&L provided the staff with a copy of the prioritization procedure, Nuclear Generation Group Manual (NGGM 305-05),
"Prioritization Process".
This procedure is now available in the NRC Public Document Room (PDR).
The staff informed CP&L that the final policy paper on ISP should be issued shortly, and no significant changes from the proposed policy paper are expected. The present draft Brunswick ISP contains a substantial update of the Level II projects. CP&L informed the staff that the next draft ISP will incorporate, in detail, the guidance of the Commission's ISP Policy paper regarding the scheduling of Level II items.

PURPOSE OF TODAY'S MEETING THIRD IN A SERIES OF WORKING-LEVEL MEETINGS BETWEEN CP&L AND NRC TO FAMILIARIZE NRC WITH THE ISP EFFORTS THESE COMMUNICATION SESSIONS WILL HELP ENSURE THE ISP SUBMITTAL AND SUBSEQUENT FEEDBACK CONTAIN NO SURPRISES FOR EITHER THE NRC OR CP&L PLAN TO FOCUS ON PRIORITIZATION PROCESS APPLICATION OF PRA TO THE PRIORITIZATION PROCESS RESPOND TO FOLLOW-UP ITEMS FROM LAST SESSION NEED CANDID FEEDBACK (WWS134)
INTEGRATED SCHEDULE PROGRAM (ISP)
PRIORITIZATION PROCESS Three (3) components Priority number (1 - 9)
Schedule Index (0 - 100)
Economic Evaluation ( 2 $250K)
Priority number Priority 1 - 3 implies fix it now (as dictated by Tech Specs)
Priority 1 - 3 automatically given a Schedule Index of 100 Priority 1 - 3 projects do not show up on ISP ISP only contains items that need attention for the long range ISP projects ranked by Schedule Index (WWS1341 INTEGRATED SCHEDULE PROGRAM (ISP)
PRIORITIZATION PROCESS (Continued)
Schedule Index provides a ranking of major projects by key attributes Nuclear Safety (32)
