Subject:

Time Extension For Report - DER 84-68 A 50.55(e) Potentially Reportable Deficiency Relating To The Essential Chiller Temperature Switch.

File: 84-019-026; D.4.33.2

Reference:

( A) Telephone conversation between L. Miller and K. Parrish on September 10, 1984 (B) ANPP-30785 (Interim Report)

Dear Sir:

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

At that time, it was estimated that a Final Report would be available by October 30, 1984.

Due to the extensive investigation and evaluation required, it is now expected that this information will be finalized by November 15, 1984, 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,

(
