IDENTIFICATZON OF THE FIRM CONSTRUCTING THE FACILITY OR SUPPLYXNG THE BASiC COMPONENT WHICH FAILS TO COMPLY OR CONTAINS A DEFECT: The DB-25 circuit breaker were refurbished by: Westinghouse Replacement Component Services Westinghouse Electric Corporation Nuclear Services Division Haymaker and Northern Pike Road Monroeville, PA 15146 The current refurbishment site is: Westinghouse Electric Corporation Assembly 5.Test Facility Cheswick Site 2000 Cheswick Avenue Cheswick, PA 15024-1358 NATURE OF THE DEFECT OR FAILURE TO COMPLY AND THE SAFETY HAZARD WHICH IS CREATED OR COULD BE CREATED BY SUCH DEFECT OR FAILURE TO COMPLY: The refurbished DB-25 circuit breaker was returned to Ginna Station with a missing pin in the operating mechanism.

The absence of this pin is believed to have contributed to the failure of the SWP1B circuit breaker to close on a manual signal from the Main Control Board.This implies that the potential exists that the breaker would not close on an auto demand and therefore not be available to perform its safety function(s).
