SUBJECT:

Shymlock of my staff concerning an enforcemnt conference to be conducteu at the Catawba Nuclear Station on September 28. 1989, at 9:30 a.m. The purpose of the meeting will be to discuss two issues. The first issue is the apparent failure to take adequate corrective action in response to a failed surveillance test on the Unit 2 turbine driven auxiliary feedwater pump. The second issue regards the apparent inability of both Unit 2 motor driven auxiliary feedwater pumps to align their suctions to the Nuclear Service Water system, the assured source of makeup water. This was discovered during the performance of a piping flush procedure. The areas we would like to discuss are identified in the enclosures.

Should you have any questions regarding these arrangements, we will be pleased to discuss them.

Sincerely,_
