                 10CFR21 INITIAL FACSIMILE NOTIFICATION



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



          NAME:     Joseph A. Widay

                    Plant Manager



          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 the internal gear positive displacement pump used

          as the fuel oil booster pump on the "B" Emergency Diesel

          Generator (D/G), (The pump is a Tuthill Model 2CF-CC and, the

          Ginna equipment identification number (EIN) is PDG05B.)





III.      IDENTIFICATION OF THE FIRM CONSTRUCTING THE FACILITY OR

          SUPPLYING THE BASIC COMPONENT WHICH FAILS TO COMPLY OR

CONTAINS

          A DEFECT:



          The pump was manufactured by:



          Tuthill Corporation

          Tuthill Pump Division

          12500 South Pulaski Road

          Chicago, Illinois 60658



          Note: This pump was purchased commercial-grade, was

          commercially-dedicated by Rochester Gas & Electric, and met all

          technical requirements included in the procurement document.



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 pump was supplied as an exact replacement (by model number)

          for the original component and was satisfactorily tested to

          meet the pump performance requirements established by the pump

          original equipment manufacturer (OEM).  The replacement pump

          was installed during a scheduled maintenance outage of the "B"

          Emergency D/G in August, 1995. During post-installation

          testing, the diesel minimum operating fuel oil pressure (as

          recommended by the diesel OEM) could not be achieved.  The

          safety hazard that could have been Treated was that the B

          Emergency D/G may not have been able to maintain design load

          rating (with the fuel oil booster pump capacity reduced).





                                                                 PAGE 3



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

          COMPLY WAS OBTAINED:



          The information was obtained on August 3, 1995.



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 two fuel oil booster pumps installed, one on the "A"

          and one on the "B" Emergency D/G. (This defect only affected

          the "B" Emergency D/G.) There were two pumps procured as

          replacement spares for the installed fuel oil booster pumps,

          and both of these spares appear to have this defect.



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:





          Corrective action for the fuel oil booster pump installed on

          the "B" Emergency D/G is complete.  The corrective action was

          to adjust the pump end play clearance to tighter tolerances by

          changing shims on the pump cover to achieve the fuel oil system

          pressure recommended by the diesel OEM.  Additional actions to

          ensure spare pumps meet these recommendations are being

          evaluated.



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:



          Subsequent to the installation of a new fuel oil booster pump,

          if fuel oil system pressure (as recommended by the diesel OEM)

          is not achieved, adjustment of pump end play clearance may be

          necessary to increase pump capacity.
