Box 53999, Sta.

Mr. M. F.
Conway Executive Vice President, Nuclear Gentlemen:
SUBJECT'IAGNOSTIC EVALUATION TEAM REPORT FOR PALO VERDE NUCLEAR GENERATING STATION - NOTICE OF VIOLATION The Diagnostic Evaluation Team (DET) Report for the Palo Verde Nuclear Generating Station was forwarded to the Arizona Public Service Company (APS) in a letter dated March 16, 1990.
The preliminary findings were discussed with APS managers on January 24, 1990.
In addition, discussions were held on April 10, 1990 regarding the proposed response to the DET Report and the submittal of an APS "business plan" which would address APS'anagement perspectives of the DET Report findings.
As discussed in the April 16, 1990 letter from J. Taylor, we understand that an initial version of a "business plan" will be provided by the end of July 1990.
Me anticipate discussing the details of the "business plan" in future meetings, Based'n the findings presented in the DET Report, it appears that several of your activities were not conducted in full compliance with NRC requirements as'et forth in the Notice of Violation, enclosed herewith as Appendix A. These apparent violations are in two areas:
(1) examples of failure to follow procedures or to have adequate procedures and (2) examples of failure to correct deficiencies or take appropriate corrective actions to preclude repetition.
The DET findings related to the program for motor operated valves (MOVs) highlight both the areas of procedural weaknesses and ineffective corrective actions.
The DET identified that the MOV data base document used by APS was inadequate to control MOV setpoints in that:
the numerous design changes associated with it made it difficult to use in the field; the setpoints were not technically supported; an as-built document for the setpoints does not.exist; and the setpoints coul'd not be easily compared to MOVATS data.
The DET also found that procedures did not exist to track the number of valve operator overthrust cycles, for valve operators known to be in an overthrust condition, to limit the number of cycles below the maximum number recommended by the vendor.
In addition, the DET identified that complete disassembly and reassembly procedures for MOVs did not exist.
- Further, the DET found that Part 21 notifications and Limitorque technical manuals had not been updated for three years.
These findings reemphasize the need to ensure that procedures'are ade'quate to properly control plant activities and are followed, and that effective corrective actions are implemented to resolve and correct problems with safety significant plant equipment, such as MOVs.
