PAGE 2 10CFR21 30 DAY WRITTEN REPORT I. ~ NAME AND ADDRESS OF THE INDIVIDUALINFORMING THE COMMISSION:

NAME: Robert C. Mecredy Vice President Nuclear Operations 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 FACILITYWHICH FAILS TO COMPLY OR CONTAINS A DEFECT:

The facility is the R.E. Ginna Nuclear Power Plant. The basic component is the engine-driven, internal gear, positive displacement pump used as the fuel oil booster pump on the "A" and "B" Emergency Diesel Generators (EDG)

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

The pumps of concern were manufactured by:

Tuthill Corporation Tuthill Pump Division 12500 South Pulaski Road Chicago, Illinois 60658 The pumps were purchased commercial-grade, were dedicated by Rochester Gas &

Electric Corporation (RG&E), and met all technical requirements included in the procurement documents.

IV. NATURE OF THE DEFECT OR FAILURE TO COMPLY AND THE SAFETY HAZARDWHICH IS CREATED OR COULD BE CREATED BY SUCH DEFECT OR FAILURE TO COMPLY:

The pumps were supplied as exact replacements (by model number) for the original and were tested to meet pump performance requirements, established within 'omponents the EDG vendor technical manual (VTM), that incorporated requirements of the pump manufacturer (Tuthill Corporation).

PAGE 3 During a scheduled maintenance outage of the "B" EDG (in August, 1995), fuel oil bo0ster pump post-maintenance testing revealed fuel oil system pressure readings of 32

~" PSIG, in the "required action" low range. (This "required action" range is an administrative band below the normal operating range of 35 to 45 PSIG, established by RG&E based on VTM guidance, historical performance data, and the application of ASME Code OMa-1988.) After other trouble-shooting activities were performed, the fuel oil booster pump was replaced with a new spare pump. With the new spare pump installed, post-installation testing revealed that fuel oil system pressure was still in the "required action" low range. This pump was then replaced with a second new pump and an unacceptable pressure was again observed.

The pump manufacturer VTM states that pump capacity is affected by rotor end play and can be adjusted by removing/adding shims from/to the pump end plates. A third pump (a rebuilt pump that had been previously used and had produced satisfactory fuel oil system pressure when installed) was removed from stock. The shimming on this pump was adjusted to reduce axial rotor end play, and then the pump was installed on the "B" EDG. Testing demonstrated that fuel oil system pressure for the "B" EDG was restored to an acceptable pressure of 44 PSIG.

The potential existed that fuel oil booster pumps could be procured that meet the pump manufacturer performance requirements, but fail to satisfy fuel oil system pressure requirements. (Note that during the procurement of the spare pumps, they were satisfactorily tested to pump manufacturer performance requirements.) If the deficient fuel oil booster pump had been installed and post-installation testing had not been performed to detect this defect, a substantial safety hazard could have existed. The basis for this conclusion is the fuel oil booster pump would not achieve the fuel oil system pressure administratively established by RG8cE; therefore, the EDG could not be guaranteed to carry its full design loading under all postulated conditions.

V. THE DATE ON WHICH THE INFORMATIONOF SUCH DEFECT OR FAILURETO COMPLY WAS OBTAINED:

The information was obtained during maintenance trouble-shooting activities performed on August 3 to August 5, 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 deficient Tuthill model 2CF-CC pumps, located as spare pumps in stock.

PAGE 4 VII. THE CORRECTIVE ACTION WHICH HAS BEEN, IS BEING, OR WILLBE TAKEN; THE NAME OF THE INDIVIDUALOR ORGANIZATIONRESPONSIBLE FOR THE ACTION; AND THE LENGTH OF TIME THAT HAS BEEN OR WILLBE TAKEN TO COMPLETE THE ACTION:

On August 5, 1995, Ginna Maintenance personnel installed a rebuilt fuel oil booster pump on the "B" EDG that restored acceptable fuel oil system pressure to the "B" EDG.

At no time was the "B" EDG declared operable with a deficient fuel oil booster pump installed.

No corrective action was necessary for the "A" EDG, which was not affected by this condition.

RG&E Procurement Engineering is working with the pump manufacturer and the EDG original equipment manufacturer (OEM) to clarify the required pump performance requirements. Upon conclusion of this effort, Procurement Engineering will revise the dedication plan for these pumps. These actions are expected to be completed by March 1, 1996.

The two deficient spare fuel oil booster pumps have been placed on "hold", pending completion of these actions.

VIII. ANY ADVICE RELATED TO THE DEFECT OR FAILURE TO COMPLY ABOUT THE FACILITY, ACTIVITY, OR BASIC COMPONENT THAT HAS BEEN, IS BEING, OR WILLBE GIVEN TO PURCHASERS OR LICENSEES:

The potential exists that fuel oil booster pumps could be procured to meet the pump manufacturer booster pump performance requirements, but fail to satisfy fuel oil system pressure requirements (established either by the EDG manufacturer or the end-user).

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 increase pump pressure.
