Dear Sir:

The NRC was notified of a potentially reportable deficiency in reference (A),

and an interim report by reference (B). At that time it was estimated that a final report would be available by January 15, 1987.

Due to the extensive investigation and evaluation required to address the complexity of this issue, a time extension is needed. It is now expected that this information will be finalized by February 16, 1987 at which time a complete report will be submitted. There is no new information or change to the interim report at this time.

Very truly yours,
