Public Meeting Summary
-Management Meeting for Dresden Nuclear Power Station October 1 Managem~nt 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 May 29, 1998, at the Dresden site and was largely focused on scram history and material condition. This October 1, 1998, meeting was primarily centered on recent difficulties with Technical Specification compliance and configuration control, work *
- control activities, and material condition improvements. From June 1998, through August 1998, the Dresden Station experienced approximately five instances where Technical 'Specification Limiting Conditions for Operation were inadvertently entered without operators being properly aware of the entry, including one instance where the Technical Specification requirements were actually violated. Com Ed presented a thorough discussion of the events, circumstances and causes contributing to their occurrence, and subsequent corrective actions* being taken by the Station. NRC representatives questioned ComEd on the specifics of some of the events and the corrective actions. The work control dialogue highlighted improvements made at Dresden from the state of work management deficiencies as of the beginning of 1998. In the area of material condition, ComEd discussed systems where improvements had resulted in relative success, such as the high pressure coolant injection and feedwater systems, as well as systems where further improvement is needed, such as the off gas system.
The licensee presented information contained in the applicable handout in Enclosure 2 during the meeting.
