Dear Mr. Sylvia:
SUBJECT:
MOTOR-OPERATED VALVEINSPECTION AT NINE MILEPOINT
UNITS
1 & 2 (NRC INSPECTION REPORT NOS. 50-220/92-82 AND 50-
410/92-82)
This letter refers to the NRC team inspection conducted on June 22 - 26, 1992 at the Nine
Mile Point Nuclear Power Stations Units
1 4 2 to evaluate the adequacy of your actions to
assure the reliability of motor-operated valves (MOVs). Specifically, our inspectors reviewed
the programs that you have developed in response to NRC Generic Letter 89-10, "Safety-
Related Motor-Operated, Valve Testing and Surveillance."
The generic letter and its
supplements provided recommendations
to the licensees for the development of a program to
ensure operability of safety-related MOVs during design-basis conditions.
Our inspectors observed that three refueling outages remain for the completion of the MOV
program at Unit No.
1 and one refueling outage remains for the completion of the program at
Unit No. 2. While the program is progressing at Unit No. 2, a significant effort, such as the
completion of design-basis
reviews, calculation of torque switch settings and the performance
of in situ design-basis
testing, remains to be completed.
A focused management
overview
willbe necessary
to successfully complete this program in accordance with the schedule
described in the generic letter.
The results of this inspection,
as detailed in the enclosed report, were discussed with you and
your staff during the exit meeting on June 26, 1992.
At the exit meeting, your staff
acknowledged the inspection findings and agreed to review the areas requiring clarifications
or improvements for resolution as summarized in Table
1 of the enclosed inspection report.
Ifyour understanding of the actions to enhance the MOV program as summarized in Table
1
is different, please notify me in writing as soon as possible.

Q
Mr. B. Ralph Sylvia
It appears that one of your activities was not conducted in full compliance with NRC
requirements,
as set forth in the Notice of Violation (NOV), enclosed herewith as
Appendix A. The control of torque switch dial settings at Unit 1 is inadequ'ate.
The NOV
.describes the failure to correctly implement a preventative maintenance procedure step, which
.
requires recording of MOV torque switch dial settings.
The verification of proper torque
switch settings is important to safety to assure that the thrust generated by the motor-operator
will be sufficient to operate the valve during accident conditions.
Your response
to this
notice should follow the instructions provided in the Appendix.
Your cooperation with us in this matter is appreciated.
Sincerely,,
Marvin W. Hodges, Director,
Division of Reactor Safety
