Duke Power Company Reply To A Notico Of Violation 413/90-29-02 Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained covering the activities referenced in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978 which includes surveillance testing.

Procedure PT/1/A/4230/53A, 1FW-28 Partial Stroke Test, Enclosure 13.2, step 8.0, requires that valve IND-7, the 1A Residual Heat Removal (ND) pump suction line drain valve, be closed and locked prior to opening 1FW-27A, the ND Pump suction valve from the Refueling Water Storage Tank in Step 11.0.

Contrary to the above, on October 18, 1990, a Non-Licensed Operator (NLO) failed to follow procedural requirements in that he signed-off Step 8.0 of PT/1/A/4200/53A indicatlag that valve IND-7 had been closed and locked when in fact the valve was locked open. Subsequently, the Control Room Operator performed Step 11.0 of the procedure which opened 1FW-27A, creating a direct flowpath from the Refueling Water Storage Tank, through an open vent valve downstream of 1ND-7, resulting in the spraydown of the ND pump room.

RESPONSE

1. Admission or Denial of Violation Duke Power admits the violation.

2. Reasons for Violation if Admitted The incident is attributed to Inappropriate action.

The operator in question signed off the valve as being in the closed position. The operator became confused in dealing with the reach rod resulting in the valve actually being left open.

3. Corrective Actions Taken to Avoid Further Violations And Results Achieved The operator involved in this event has been counseled on the importance of determining valve position and the need to notify supervision when questions arise. This was considered an isolated case.

A letter was written by Maintenance Engineering Services (MES) on 11/14/90 requesting Radiation Protection, Chemistry and Operations to provide l

contacts to help establish an appropriate Preventive Maintenance (PM) program for the reach rods.

4. Corrective Actions to be Taken To Avoid Further Violations Maintenance Engineering Services will evaluate the reliability of valve reach rods and the need-for a Preventive Maintenance program for reach rods and improve general reliability, (no PM is currently performed). This evaluation will be complete by 3/1/91. ,

5. Date of Full Compliance Duke Power is now in full compliance.
