File: 84-019-026; D.4.33.2
Reference:
Telephone Conversation between D. Hollenbach and T. Bradish on July 24, 1984
Dear Sir:
The NRC was notified of a potentially reportable deficiency in the referenced telephone conversation. At that time, it was estimated that a determination of reportability would be made within thirty (30) days.
Due to the extensive investigation and evaluation required, an Interim Report is attached. It is now expected that this information will be finalized by September 20, 1984, at which time a complete report will be submitted.
Very truly yours, g
