Subject:
Palo Verde Nuclear Generating Station Unit 1 Notice of Violation (50-528/83-44)
Docket No. STN 50-528 File: 84-019-026
Reference:
Letter from T. Young, Jr. to C. C. Andognini, (NRC IE Report 50-528/83-44), dated December 13, 1983.
Dear Mr. Martin:
As a result of the inspection conducted on November 1-30, 1983, and in accordance with NRC Enforcement Policy, 10CFR, Part 2,
Appendix C, 47-FR-9987, the following violation was identified:
Appendix B of 10CFR50, Criterion V states in part that " Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and I
shall be accomplished in accordance with these instructions, procedures i
or drawings."
i Contrary to the above, on September 24, 1983 the No. 2 steam generator was over filled with water to the extent that water was pumped into the steam line of the. steam generator.
This occurred due to an incorrect valve line up which had not been properly reviewed prior to its implementation.
This is a level IV Violation (Supplement II).

o Mr. John B. Martin Palo Verde Nuclear Generating Station Notice of Violation (50-528/83-44)
January 13, 1984 NOLD 84-20 Arizona Public Service Company Response to the Notice of Violation The Corrective Steps Which Have Been Taken and the Results Achieved:
The Independent Safety Engineering Group (ISEG) has performed a special investigation of the above noted incident.
PVNGS Unit 1 Operations' personnel have responded to the four (4) primary recommendations of the special investigation.
These responses were developed quickly and implemented effectively to prevent a recurrence of such an incident.
A summarization of those actions follows:
Recommendations:
1.
Control Room Operators must ensure that the proper flow path exists for even the most routine action. An actual line M* line, valve by valve, origin to destination verification of flow path using the system status prints should be utilized.
Response
Each Crew has reviewed Operations Departmental Instruction #17, System Valve and Breaker Status, and the use of the laminated system status prints.
Their importance during all system manipulations has been stressed.
2.
Operations personnel should not operate equipment or systems blind, particularly where a significant parameter is out of service.
They should be instructed / advised to compare the consequences of continued operation in the abnormal mode versus the conservative action of shutting down the affected system until repair is complete.
Response
Inadequate instrumentation decisions shall be made on a judgement basis by the Shift / Assistant Shift g>
Supervisors.
Specifically, the Supervisor shall determine plant, system and/or test status and priority when making the decision to operate without proper instrumentation available.
The above directive was issued to all Unit 1 Shift Supervisors and was reviewed by the Unit 1 crews.

'.,%a Mr. John B. Martin Palo Verde Nuclear Generating Station Notice of Violation (50-528/83-44)
January 13, 1984 NOLD 84-20 3.
Reinforce to all Operations' personnel the need for complete shift turnovers, particularly when an evolution is in progress.
- Also, ensure that -the oncoming shift understands the scope of the evolution, its complete flow path, and any restrictions that may impact its completion.
Response
The importance of complete shift turnover has been stressed during Shif t Supervisor meetings, (September 28 and November 30).
Tne significance of complete shift turnover with regard to this situation was discussed in detail during the September 28, Shift Supervisors' meeting.
Shift Supervisors discussed the matters covered during these meetings, subsequently with their crews.
4.
This event emphasizes the need for Nuclear Operator III's to be questioning, and thorough, and to constantly be aware of their actions and instructions.
Inpress upon those personnel directly under their supervision the need to support and verify (for clarification, understanding and completeness) those instructions that address valve manipulations.
Response
Procedures and their use, especially during "off normal" evolutions, have been stressed in Operations' correspondence and directives.
Corrective Actions Which Will Be Taken To Avoid Further Noncompliance.
All actions for Unit 1 are complete.
Date When Full Compliance Will Be Achieved.
We are in full compliance as of January 6, 1984
