. CATAWBA NUCLEAR STATION-REPORT NUMBER: SD413,414/81-05 REPORT- DATE: May 29 1981 FACILITY: Catawba Nucl' ear Station, Units l&2-IDENTIFICATION ^0F DEFICIENCY:

The Diesel Generator Control-Panels were inspected and it was. discovered that the panel-wiring did not agree with the drawings, and some of.the components did not agree with the~ Bill of Materials. This deficiency was identified on May 1, 1981. .

INITIAL REPORT:

On M'ay'1, .1981, Mr. Art Johnson of NRC Region II, Atlanta, Georgia was notified of.this deficiency by Mr. W. O. Henry, and Mr. W. J. Foley of Duke Power Company, Charlotte, NC 28242.

SUPPLIER AND/0R COMPONENT:

RTE Delta Co. of Stockton, California, a sub-vendor to Transamerica Delaval, built the control panels for Catawba Units 1&2 diesel generators. The diesels are designated'lA, 1B, 2A, 28.

DESCRIPTION OF DEFICIENCY:

A connection diagram for the Diesel Generator Control Panels was prepared by RTE Delta Co when the panels were being built. These drawings were submitted to Duke Power Company as the panels were being shipped.

Duke Power Company compared these connection diagrams to the schematic diagrams, that were submitted and approved by Duke Power Company before the panels were

~

. built; several errors were identified. The panel wiring was then checked and it was determined that the panels' wiring did not agree with either the connection diagrams or the schematic diagrams. Additionally, some of the components in the panels did not agree with the Bill of Materials.

ANALYSIS OF SAFETY IMPLICATION:

If the deficiencies were not corrected, because of the number of errors involved, the diesels may'not have operated as orignally' intended. .

Because these errors were in all of the panels, both of the diesels for each unit could have been inoperable. This could have resulted in the unavailability of on-site power.

CORRECTIVE ACTION:

To correct these deficiencies 'the following action was taken. All the wiring drawings ixt these panels wer e reviewed by Duke Power Company, Delaval, and

-Delta. All of:the drawings were checked to.make sure they were functionally correct and that they agreed with each other. Delta and Delaval reviewed

. the Bill"of Material drawings 'against the panels to make sure all the com-ponents listed were the components.that they had seismically qualified in the panel.

After the drawings'and corrected drawing's were corrected, checked Delta resired each component in the all. fourto.panels panels determine per the if it' matched the Bill of Material Drawings. Catawba NCI's 8889, 8900, 8901, 7

- 8902 werel written tc implement this work.

-All of the' components that do not match the Bill of Materials will be replaced witi_the correct component. Catawba NCI #11611 was written to implement this work.
