Subject:
Interim Report - DER 84-67 A 50.55(e) Potentially Reportable Deficiency Relating To Target Rock Solenoid Valves.
File: 84-019-026; D.4.33.2.
Reference : Telephone Conversation between D. Hollenbach and T. Bradish on September 7, 1984 1
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 October 30, 1984, at which time a complete report will be submitted.
Very truly yours, ONN E. E. Van Brunt, Jr.

are Target Rock solenoid valves used in steam: drain trap
. applications. These'are fail-close valves.that did not stroke
. when. required during testing. The control room indication lights were initially reported not to' reflect the true state of the valve.- However, later investigation indicated that'the valves were mechanicallyf stuck;.
II..
Approach To and Status Of ~ Proposed Res'olution -
1 Two other DERs -(84-58 and 84-63) have been written to document
~
similar situations on Target Rock solenoid valves for other i
systems.
i-Bechtel Engineering is currently studying this problem to determine Reportability and technical ' justification for l-corrective action.

and Submittal of the Final Report The complete evaluation and final report are forecast to be completed by October 30, 1984 l
