                 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 a 350 HP, 1800 RPM, 460 VAC, 3 phase, 500GP Frame, 1.15
     SF, vertical hollow shaft motor for use as a Service Water (SW) pump
     motor.  This component was installed at the R.E. Ginna Nuclear Power
     Plant in July, 1996, as a modification to upgrade the existing 300
     HP motor for the "A" SW pump to a 350 HP motor.

III. IDENTIFICATION OF THE FIRM CONSTRUCTING THE FACILITY OR SUPPLYING
     THE BASIC COMPONENT WHICH FAILS TO COMPLY OR CONTAINS A DEFECT:

     The motor was a commercial-grade motor manufactured by:

          U.S. Electrical Motors
          Division of Emerson Electric Co.
          8100 W. Florissant Ave.
          PO Box 3946
          St. Louis, MO 63136

     The motor was procured from:

          Auburn Armature, Inc.
          48 Canoga St.
          Auburn, NY 13021

     Note: This motor was purchased commercial-grade, was commercially-
     dedicated by Rochester Gas & Electric, and satisfied all testing
     requirements included in the procurement documents.


                                                                   Page 3

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 motor did not pass post-modification functional testing.  The
     motor was removed from the "A" SW pump, disassembled, and inspected.
     Inferior workmanship was discovered, most notably damaged motor
     leads.  In the scenario of the "C" SW pump out of service and a
     concurrent loss of power to Bus 17, a loss of all SW would occur if
     the "A" SW pump failed to operate due to the identified defect.

V.   THE DATE ON WHICH THE INFORMATION OF SUCH DEFECT OR FAILURE TO
     COMPLY WAS OBTAINED:

     The information was obtained on August 5, 1996.

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 four (4) SW pumps located in the Screenhouse Building at
     Ginna Station. The "D" SW pump had its original motor replaced in
     August, 1995, with a motor manufactured by U.S. Electrical Motors.
     This motor was tested satisfactorily at that time and has operated
     trouble-free since.  Three (3) more motors, of similar design to the
     "D" SW pump motor, were procured by a separate purchase order.  Two
     of these motors were discovered to be detective and have been
     refurbished.  One of the refurbished motors has been installed.

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:

     The "A" SW pump remained inoperable until the defective motor was
     removed, refurbished, reinstalled, and satisfactorily tested.  Thus,
     corrective action is complete for the installed motor.  Similar
     corrective actions have been completed for one of the spare motors.
     The similar motor, installed as the "D" SW pump motor in August,
     1995, has shown no signs of motor degradation.  However, this motor
     will be removed and replaced by a refurbished spare motor by
     November, 1996.  The motor (removed from the "D" SW pump) and the
     other spare motor will disassembled and inspected, and refurbished,
     if necessary, prior to use.  Rochester Gas & Electric Ginna Station
     maintenance department will be responsible for these actions.

                                                                   Page 4

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:

     Source surveillance during motor assembly may have detected this
     defect.  Additionally, physical inspection upon receipt could be
     specified in the purchase order, and completion of commercial
     dedication could be dependent upon satisfactory completion of post-
     modification functional testing.
