Cl ENCLOSURE 1 RESTATEMENT OF NOTICE OF VIOLATION"B" 50-529/97-15-03 NRC INSPECTION CONDUCTED JULY 27 THROUGH SEPTEMBER 6, 1997 INSP ECTION REPORT NO.50-528/529/530/97-15 W1 RESTATEMENT OF NOTICE OF VIOLATION"B" 50-529/97-15-03 During an NRC inspection conducted on July 27 through September 6, 1997, two violations of NRC requirements were identified.

In accordance with the"General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, violation"B" is listed below.(Note-'o response to Violation"A" is required.)

Technical Specification 6.8.1 requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.Regulatory Guide 1.33, Revision 2, Appendix A, requires, in part, written procedures for procedural adherence.

Procedure 01DP-OAP01,"Procedure Process," Revision 4, Step 7.2, required, in part, that procedure users are responsible for adhering to the requirements of the procedure.

Contrary to the above, on July 23, 1997, licensee personnel failed to adhere to the requirements of Procedure 70TI-9SP03, Chemical Passivation Of Spray Pond Piping, Revision 0.Specifically, Step 4.2 which required the control room supervisor/shift supervisor to be briefed on the test procedure and that the work group obtain permission to proceed with the test.These requirements were not performed.

Also, Step 5.8, which required a pretest briefing to be conducted, was not performed.

.This is a Severity Level IV violation (Supplement 1)50-529/97-15-03.

1 i ENCLOSURE 2 REPLY TO NOTICE OF VIOLATION"B" 50-529/97-15-03 NRC INSPECTION CONDUCTED JULY 27 THROUGH SEPTEMBER 6, 1997 INSPECTION REPORT NO.50-528/529/530/97-15 I

REPLY TO NOTICE OF VIOLATION"B" 50-529/97-15-03 Reason For The Violation On July 23, 1997, temporary piping was installed by divers in the Unit 2 spray pond.The procedure used to install the temporary piping was test and inspection procedure 70TI-9SP03,"Chemical Passivation of Spray Pond Piping." The prerequisite and initial condition sections of 70TI-9SP03 included individual signoffs for obtaining Shift Supervisor authorization and performing a prejob briefing.The Project Manager discussed the test plan with the Work Control Senior Reactor Operator and afterwards briefed the diving crew;however, the engineer responsible for conducting the test did not contact the Shift Supervisor and obtain authorization nor did he conduct and document a thorough prejob briefing with all appropriate personnel.

Failing to notify the Shift Supervisor and conduct a thorough prejob briefing resulted in missed opportunities to prevent events that compromised the personal safety of the divers.Specifically, a valve that was being used as a safety boundary during installation of the temporary piping was cycled open while divers were in the spray pond and unmonitored service air was used by some divers as a breathing air source during diving operations.

Failing to complete the prerequisite and initial conditions of 70TI-9SP03 prior to installing the temporary piping in the spray pond was contrary to approved station procedures and was a violation of Technical Specification 6.8.1.

Palo Verde's significant investigations of the event determined the reason for the violation was poor work practices on the part of the responsible engineer.A contributing factor was poor communications between operations, engineering, maintenance, and scheduling.

Corrective Ste s That Have Been Taken and Results Achieved Significant investigations were performed in accordance with Palo Verde's corrective action program.Based on the results of the investigations, the responsible engineer was coached on procedural use and adherence.

Corrective Ste s That Will Be Taken To Avoid Further Violations A newsletter will be issued by strategic communications on procedure use and adherence and procedure implementation, including responsibilities for impact reviews C and training for affected personnel by October 30, 1997.Training will be provided to all engineering support personnel on procedure use and adherence, procedure preparation and implementation, including responsibilities for impact reviews and training for affected personnel by January 31, 1998

Date When Full Com liance Will Be Achieved Full compliance was achieved on July 23, 1997 after the first phase of temporary piping was installed and 70TI-9SP03 suspended.

On September 12, 1997, prior to continuing work under 70TI-9SP03, a thorough prejob briefing was conducted and the Shift (Supervisor's authorization was obtained.
