Dear Sir:

The NRC was notified of a potentially reportable deficiency in Ref-crence (A) and an Interim Report was transmitted by Reference (B).

At that time,it was estimated that a Final Report would be available by May 17, 1985.

The bolt nut retention mechanisms have been installed on the affected

Presently, the Project is completing the evaluation for reportability and assembling the final written report.

It is expected the Final Report will be transmitted to the NRC by June 15, 1985.

Very truly yours,
