IE Bulletin 85-03 Report Summarizing Program Completion R.E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Stahle:
Attached is the summary report required by IE Bulletin 85-03 dated November 15, 1985 which requested that licensees develop and implement a program to ensure that switch settings on motor-operated valves in the high pressure coolant injection and emergency feedwater systems are set properly. This fulfills the requirements of IEB 85-03.
Very truly yours obe . mit Vice President Production and Engineering Attachment xc: U.S. Nuclear Regulatory Commission Region I 475 Allendale Road King of Prussia, PA 19406 xc: Ginna Senior Resident Inspector 8807130068 880708 PDR ADOCK 05000244 8 PNU
ATTACHMENT 1 REPORT ON COMPLETION OF PROGRAM IE BULLETIN 85-03 INTRODUCTION On November 15, 1985, the NRC Office of Inspection and Enforcement issued IE Bulletin 85-03: "Motor-Operated Valve Common Mode Failures During Plant Transients Due to Improper Switch Settings". The purpose of the Bulletin was to request licensees to develop and implement a program to ensure that switch settings on motor-operated. valves in the high pressure coolant injection and emergency feedwater systems are selected, set and maintained correctly to accommodate the maximum differential pressures expected, on these valves during both normal and abnormal events within the design basis. IE Bulletin 85-03 required a 180 day response which was transmitted by our letter dated May 14, 1986. IE Bulletin 85-03 also required a written report within 60 days of completion of the program. As stated in our letter dated December 4, 1987, the program was scheduled for completion within 60 days of startup from the 1988 refueling outage.
The program was completed as . scheduled and this report provides the required information.
VERIFICATION OF PROGRAM COMPLETION The 1988 refueling outage ended on March 9, 1988 and the program described in Attachment 2 was completed by May 8, 1988. The Attachment 2 program and Ginna procedures ensure that switch settings of the motor-operated valves (MOVs) listed in the program are selected, set and maintained correctly to accommodate the maximum differential pressures expected on these valves during both normal and abnormal events within the design basis throughout the life of the plant. An administrative procedure addresses use of the above program in preventive maintenance and prescribes testing activities to be -performed on a periodic basis.
Maintenance procedures are then used to implement maintenance and testing activities by providing explicit instructions for maintenance and specifying what testing is required after certain t'ypes of maintenance are performed to ensure valve operability. The test interval as described in the Program may be altered based both on industrial experience or in-plant data.

SUMMARY
OF- AS-POUND CONDITION Table 1 presents a summary of the findings as to valve operability prior to any adjustments as a result of the Bulletin. Prior to the use of the, program described in , valve operability was based on the following parameters:
~ stroke time; open and close
~ verification of correct valve position indication
~ acceptable motor currents Based on these parameters, all valves in the program were operable.
The program using MOVATS methodology and equipment provided additional parameters by which valve operability could be assessed. Table 1 presents the as-found valve operability as judged by the program criteria and the reason for the finding. It should be noted that these abnormalities did not necessarily make the valve inoperable. The following is a summary of the significant MOV abnormalities found.
SUMMARY
OF SIGNIFICANT MOV ABNORMALITIES No.
Bypass switch improperly set 14 47 Incorrect thrust 20 67 Unbalanced torque switch 28 93 Valve backseating Unbalanceable torque switches 19 63 Torque switch abnormalities 13 ~
Miscellaneous abnormalities S1*
The total number of valves tested was 30.
- Number represents sum of miscellaneous abnormalities.
SUMMARY
OF DATA OBTAINED FROM VALVE OPERABILITY PROGRAM Table 2 describes the valve and operator. Table 3 contains a summary of the data obtained during the testing of the valve listed on Table 2. Table 4 provides the justification, based on the program in Attachment 2, that the valve will operate properly at its design basis.

,Therefore, the AS-FOUND T.S.S. vs. thrust may differ from the AS-LEFT T.S.S. vs. thrust.
- To prevent overthrusting, the open torque switch was set to a minimum before opening the valve into the load cell. The thrust at'he torque switch minimum setting was extrapolated to the as-found torque switch setting and was found to exceed manufacturers rating.
