THIS PART 21 INVOLVES RECEIVING A REFURBISHED DB-25 CIRCUIT BREAKER

WITH

A MISSING PART.



THE LICENSEE RECEIVED A REFURBISHED DB-25 CIRCUIT

BREAKER(REFURBISHED IN

1992) FROM WESTINGHOUSE REPLACEMENT COMPONENTS SERVICES,

MONROEVILLE, PA.

THE REFURBISHED BREAKER WAS RETURNED TO THE LICENSEE 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 ALSO IMPLIES THAT

THE

POTENTIAL EXISTS FOR THE BREAKER NOT TO CLOSE ON AN AUTOMATIC

DEMAND AND

THEREFORE NOT BE AVAILABLE TO PERFORM ITS SAFETY FUNCTIONS.  THERE

ARE 41

PERMANENTLY INSTALLED DB-25 BREAKERS IN THE SCREEN HOUSE AND

TURBINE

BUILDINGS AT THE SITE.  ALL OF THE REMAINING BREAKERS WERE VISUALLY

INSPECTED TO VERIFY THE PIN IN QUESTION WAS INSTALLED.  NO OTHER

BREAKERS

WERE FOUND TO BE MISSING THE PIN.



THE RESIDENT INSPECTOR WAS NOTIFIED.

          10CFR21 INITIAL FACSIMILE NOTIFICATION



I.        NAME AND ADDRESS OF THE INDIVIDUAL INFORMING THE COMMISSIONS



     NAME:     Joseph A.  Widay

     ADDRESS:  Rochester Gas & Electric Corporation

               89 East Avenue

               Rochester, New York 14649



II.       IDENTIFICATION OF THE FACILITY, THE ACTIVITY, OR THE BASIC

          COMPONENT SUPPLIED FOR SUCH FACILITY WHICH FAILS TO COMPLY OR

          CONTAINS A DEFECT:



     The facility is the R.E. Ginna Nuclear Power Plant.  The basic

     component is a Westinghouse DB-25 circuit breaker.  This component

     was installed at Ginna Station in a Class 1E Safety Related 480 Volt

     AC bus.  The breaker was the power supply feed breaker for the "B"

     Service Water Pump (52/SWP1B).



III.      IDENTIFICATION OF THE FIRM CONSTRUCTING THE FACILITY OR

          SUPPLYING 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 & Test Facility

          Cheswick Site

          2000 Cheswick Avenue

          Cheswick, PA 15024-1358



IV.       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 DE-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 functions.



                                                       Page 2



V.        THE DATE ON WHICH THE INFORMATION OF SUCH DEFECT OR FAILURE TO

          COMPLY WAS OBTAINED:



     The information was obtained on May 13, 1998.  An attempt was made

     to start the "B" Service Water Pump during testing and it failed to

     close on a manual signal from the Main Control Board.  During the

     troubleshooting the missing part was discovered.



VI.       IN THE CASE OF A BASIC COMPONENT WHICH CONTAINS A DEFECT OR

          FAILS TO COMPLY, THE NUMBER AND LOCATION.OF ALL SUCH

COMPONENTS

          IN USE AT, SUPPLIED FOR, OR BEING SUPPLIED FOR GINNA STATION:



     There are forty-one, permanently installed DB-25 breakers in the

     Screen House and Turbine Buildings at Ginna Station.  Of these,

     eleven breakers are Class 1E Safety Related.



VII.      THE CORRECTIVE ACTION WHICH HAS BEEN, IS BEING, OR WILL BE

          TAKEN; THE NAME OF THE INDIVIDUAL OR ORGANIZATION RESPONSIBLE

          FOR THE ACTION; AND THE LENGTH OF TIME THAT HAS BEEN OR WILL BE

          TAKEN TO COMPLETE THE ACTION:



     A spare DB-25 circuit breaker was inspected, tested and installed to

     restore the "B" Service Water Pump to service.



     All of the remaining DB-25 breakers were visually inspected to

     verify that the pin in question was installed.  No other breakers

     were found to be missing the pin.



VIII.     ANY ADVICE RELATED TO THE DEFECT OR FAILURE TO COMPLY ABOUT

THE

          FACILITY, ACTIVITY, OR BASIC COMPONENT THAT HAS BEEN, IS BEING,

          OR WILL BE GIVEN TO PURCHASERS OR LICENSEES:



     Both in-service and receipt inspections can verify the presence of

     the pin in question.  It should be noted that the "B" Service Water

     Pump breaker was refurbished in 1992.
