ENCLOSURE 2 t

Meeting Summary The Regional Administrator opened the meeting by stating that the NRC has received the Carolina Power and Light Company (CP&L) submittals for the Brunswick Unit 2 Integrated Restart Schedule and the Corporate Improvement initiatives.

He expressed concern with the lack of quantitative goals for those items that will not be 100 3ercent complete before restart.

CP&L's proposed readiness reviews of bot 1 cquipment and personnel which are described i

in the November 30, 1992, submittal need to be strengthened.

He requested that CP&L meet with the NRC after completion of their readiness reviews to present their results.

CP&L representatives provided an overview of the progress on the Unit 1 scope and schedule.

The system work logic has been defined and is being sequenced i

into the outage networks.

A definitive plan will be submitted by December 30, 1992.

The licensee emphasized that their commitments for restart of Unit 2 are contained in Appendix 3 to their July _ 23, 1992, submittal.

Discussion of the status of each item is contained in their November 30, 1992 letter. The licensee intends to conduct their readiness review by their Nuclear Assessment Department, and will use INPO to review select systems and to train Brunswick's personnel.

Inspections of the site's four Emergency Diesel Generators is continuing and will be performed sequentially and not in parallel.

Shutdown risk is being performed by a process comparable to NUMARC 91-06.

This will ensure defense in depth.

Changes to the scheduled work are assessed for risk prior to implementation. Diesel Generator No. 1 issues are being actively pursued.

Upon completion of repairs, the diesel will undergo break-in as well as a 13-day endurance run.

The backlog review of Short-term Structural Integrity (STSI) issues is continuing using the criteria specified in PN-30 to determine which items can be delayed until after restart.

However, the licensee indicated that all STSI issues will be completed by the end of the next Refueling Outage.

The validation of previous hotside/coldside_ walkdowns began on December 1.

1992.

The percent of revalidation will depend on the number of discrepancies identified and the licensee's evaluation of any operability question.

Walkdowns of the miscellaneous steel verification program are complete and components requiring repair are being corrected.

Building walls requiring repair will be completed by the end of January 1993.

During the closing remarks the Regional Administrator stated that the tour of l

the_ facility indicated _that progress was being made in rectifying deficient conditions.

He believed the-meeting to be very productive.

He suggested the next meeting be held in early January to maintain communications on the status of open issues. The next meeting agenda-should include as a minimum:
