I.   NAME AND ADDRESS OF THE INDIVIDUAL INFORMING THE COMMISSION:



     NAME:     Robert C.  Mecredy

               Vice President Nuclear Operations Group



     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 circuit 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 Company

          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 DB-25 circuit breaker was refurbished in 1992 and returned to

     Ginna Station with a missing pin in the operating mechanism.  This pin

     is a subcomponent of the operating mechanism, is not separately

     identified in the vendor manual, nor is it addressed as a customer-

     serviceable item.  The absence of this pin is believed to have

     contributed to the failure of the SWP1B circuit breaker to close on a

     manual signal (manipulation of the circuit breaker control switch)

     from the Main Control Board.  This implies that the potential exists

     that the breaker would not close on an automatic demand and therefore

     would not be available to perform its safety function.



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 the circuit

     breaker failed to close on a manual signal from the Main Control

     Board.  During the troubleshooting the missing pin 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 circuit 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 in May, 1998.



                                 Page 3



     All of the remaining DB-25 breakers were visually inspected by Ginna

     Station Electrical Maintenance personnel 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:



     The industry was notified via INPO Nuclear Network, Event 134363.

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

     pin.  It should be noted that the "B" Service Water Pump breaker was

     refurbished in 1992.
