NRC DOCKET 50-321 OPERATING LICENSE DPR-57 VIOLATION 90-15-01 AND GPC RESPONSE

{

VIOLATION 90-15-01 l Technical Specification 6.8.1.a requires that written proceduras be established, implemented, and maintained as recommended in Appendix "A* of i Regulatory Guide 1.33, Revision 2, February 1978. '

Section 4 of Appendix "A" of Regulatory Guide.l.33 recommends procedures for the operation of the Emergency Core Cooling Systems. The Core Spray l system is an Emergency Core Cooling System at Plant Hatch. '

t Procedure 34S0-E21-001-IS, Rev. 8, ' Core Spray System," provides written instructions for the operation of the Unit 1 Core Spray System and  ;

specifies that valves IE21-F0258 and IE21-F027B be maintained in the closed  :

position and that valve IE21-F30llA be maintained in the open position when the system is in its standby mode.  ;

Contrary to the above, between July 23-25, 1990, valves IE21-F025B and  !

lE21-F027B were found in the open position and valve IE21-F30llA was found  ;

in the closed position. At the time of these findings, Unit I was operating at approximately 100 percent of rated power and the Core Spray system was in its normal standby mode. .

This is a Severity Level IV Violation (Supplement 1). l RESPONSE TO VIOLATION 90-15-01 Admission or denial of violation:

The violation occurred as described in the Notice of Violation.

l ENCLOSURE 1 (Continued) l yl0LAT10N 90-15-01 AND GPC RESPONSI l Reason for the violation:

f The first event, in which valves IE21-F025B and IE21-F027B were found i mispositioned, was caused by a less than adequate procedure. The Core i Spray System had been aligned to the Condensate Transfer System, the alternate keep-fill system, per plant procedure 3450-E21-001-IS, " Core .j Spray System," on 5/14/90. This was done because both Jockey Pumps, the  ;

primary keep-fill system, had been taken out of service on Clearance  ;

l-90-1261. When the Core Spray System was aligned to the Condensate Transfer System, valves IE21-F0258 and IE21-F027B were opened as required ,

by the procedure.

Jockey Pump IE21-C002B was returned to service on 5/21/90. As part of the return-to-service activities, an operability test was performed on the  :

Jockey Pump. This was done per the " Jockey Pump Startup" section of procedure 34S0-E21-001-IS. This section of the procedure does not require r valves IE21-F025B and IE21-F0278 to be verified to be closed.

l Consequently, the procedure was not adequate to ensure valves IE21-F025B -

and IE21-F027B were returned to their proper position when transferring from the alternate keep-fill system to the primary keep-fill system.

The second event, in which valve IE21-F30llA was found mispositioned, was caused by personnel error. Instrument and Control (l&C) technicians who '

i performed procedure 57SV-E21-001-IS, " Core Spray Discharge Line level Instrument FT&C, on 7/9/90 failed to follow procedural requirements  ;

regarding the positioning, independent verification, and sealing in position of valve IE21-F30llA. The first I&C technician failed to follow

• l' procedural requirements in that he failed to open the valve as required by procedure 57SV-E21-001-IS and he sealed it in position contrary to the requirements of procedure 51GM-SPR-001-0N, " Sealing of Instrument Valves."

The second I&C technician failed to follow procedural requirements in that -

he failed to verify independently the valve was in the open position as ,

required by procedure 57SV-E21-001-IS and he failed to seal it in the open  !

position as required by procedure 51GM-SPR-001-0N.

VIOLATION 90-15-01 AND GPC RESPONSE Corrective steos which have been taken and the results achieved:

As a result of these events, the following actions have been taken:

1. Upon discovery, the mispositioned valves were placed in their correct positions. Valves 1E21-F0258 and IE21-F027B were closed on 7/24/90 and valve IE21-F30llA was opened on 7/25/90.

2. Procedure 3450-E21-001-15 was marked-up to include the necessary steps in the " Jockey Pump Startup" section to ensure valves lE21-F025A and B and IE21-F027A and B are closed. The procedure revision currently is in the review and approval process and will be issued effective by 9/28/90. (The designs of the Unit 1 and Unit 2 Core Spray Systems are different in that the Unit 2 Core Spray System does not have an alternate keep-fill system; therefore, procedure 3450-E21-001-25, " Core Spray System," does not need to be revised.)

3, The two I&C technicians were disciplined per GPC's Positive Discipline Program.

Corrective steos which will be taken to avoid further violations:

No further corrective actions are necessary to prevent recurrence.

Date when full como11ance will be achieved:

For the first eveht, full compliance was achieved on 7/24/90 when valves 1E21-F025B and 1E21-F027B were moved to the correct (closed) position.- For the second event, full compliance was achieved on 7/25/90 when valve 1E21-F3011A was moved to the correct (open) position.
