Dear Sir:

The NRC was notified of a potentially reportable deficiency in Ref erence ( A), an Interim Report was transmitted by Reference (B), and Time Extensions were requested by References (C), (D), (E), (F), and (C). At that time, it was estimated that a Final Report would be available by September 25, 1984 Due to the extensive investigation and evaluation required, it is now expected that this inf ormation will be finalized by October 25,1984, at which time a complete report will be submitted.

There is no new inf ormation or change to the Interim Report at this time.

Very truly yours, t
