Dear Mr. Butler:
During the week of August 26, 1985, the NRC Staff and its consultants performed an on-site' audit of the Clinton Power Station Seismic and Dynamic Qualification of Equipment. Twenty pieces of equipment were selected for the audit, including two surprise items, to determine the adequacy of the equipment qualification program.
As a result of the audit. 12 specific open items were identified as well as 7 generic open items. The purpose of this letter is to provide a schedule for closure for each open item as specified by your Staff.
Attached is a description of each open item with a corresponding closure date. Please contact us if you have any questions on this matter.
