Public Meeting Summary Management Meeting for Dresden Nuclear Power Station March 10 Management Meeting Summary:

This management meeting was conducted as a part of continuing, periodic oversight of the performance of the Dresden Station. The most recent past public management meeting on Dresden was conducted on December 15, 1998, at the Dresden Station and was largely focused on material condition improvements and reviews of the Operations, Maintenance, Engineering, and Plant. Support departments. This March 10, 1999, meeting was primarily centered on plant performance and planned material condition improvements, a review of the just completed Unit 3 refueling outage, and a functional review of the Operations, Maintenance, Engineering, Plant Support, and Nuclear Oversight departments. NRC representatives questioned Com Ed management personnel on the specifics of some of the issues and planned licensee corrective actions.

The licensee presented information contained in the applicable handout in Enclosure 2 during the meeting.
