____.m MTACilliENT I VIOLATION:
Technical Specification 6.8.1 requires that written procedures shall be established, implemented and maintained that meet or exceed the requirements of Regulatory Guide (Reg Guide) 1.33, Revision 2, " Quality Assurance Program Requirements (Operation)".
Reg Guide 1.33, Appendix A requires that procedures be written for surveillance testing of the containment Spray system.
(
Station procedure 604.4.007, Revision 13, " Containment Spray and Emerger.cy Service Water System 1 Pump Operability and Incervice Test", step
- 6. 20, requires the Containment Spray and Emergency Service Water (ESW) purnps to be secured if inservice testing (IST.'.
is not required to be performed.
Contrary to the above, on April 20,
- 1992, the Control Room operator failed to implement procedure 604.4.007 in that the containment Spray and ESW pumps were not secured when performance of IST was not required before proceeding to the next step in the e
procedure.
As a result of this action, the system was aligned to spray the containment when the operator placed the system control switch in the AUTO position, and approximately 825 gallons of water were sprayed into the containment.
GPUN RESPOE4El GPU Nuclear concurs in the violation.
The incident has-been attributed to operator error, in that the control Room Operator performing the surveillance procedure f ailed tc apply self-checking in_its execution.
The operator overlooked a step in the procedure requiring him to stop the Containment Spray Pump, and proceeded to reposition the mode switch with the pump stil.1 running.
This allowed approximately 825 gallons of
-torus water to-be sprayed into the Drywell.
Corrective Actions Taken and Results Achieved:
The pump was tripped approximately 29 seconds after the error, and flow to the Drywell was terminated.
The operators
-took the_ actions required by the Alarm Besponse Procedures for the alarms received.
The expectationb of Operations Department Management regarding compliance with the operations Department Standard t
on Procedure Compliance were communicated to all department personnel.

The operator involved in the procedure violation was disqualified. Operations Department Management discussed the need to perform self-checking with the
- operator, and i
emphasized the Operations Department Standard on Procedure compliance.
A training ana requalification program was developed for the operator who had performed the surveillance, to be completed prior to resuming
.t icensed duties.
The Station Director met with all operating shift crews to discuss management's expectations regarding human performance issues and the requirement for all operators to use self-checking techniques.
Additionally, temporary proceduro changes were issued for the surveillance procedures which separated and clarified the required actions involved into distinct steps (one for each system).
Corrective Action t.g be Taken to Ay_oid Further V.tolationgi Procedure changes will be developed for the two surveillance procedures, which will upgrade them to the format required by the Procedure Writer's Standard.
The concept of Crev Self-Checking will be developed and training-implemented for all operating crews _.
Qafe When-Full Compliance was Achieved:
l.
Full compliance was ar.hj eved on April 20, 1992, when the running Containment Spray Pump was tripped, approximately 29
- seconds after the error was made.
