==Dear Dr. Murley:==
 
Rochester Gas and            Electric is submitting the attached 10CFR, Part 21      Evaluation and Notification.          The notification concerns a potential material defect of SMA type torque switches supplied by Limitorque during the late 1960's.
One      hundred seven (107) of one hundred eight (108) motor operated valves          (MOV) installed at R.E. Ginna Nuclear Power Plant, actuator wiring configurations were inspected in conjunction with an on-going Electrical Control Configuration Drawing Upgrade Project.
Twenty-six had SMA-type torque switches installed. The SMA-type torque switch is a black fibrous, laminated, phenolic material.
Ten of the twenty-six switches demonstrated                loose one-quarter inch socket head mounting screws and nine of the twenty-six demonstrated loose wire termination bolts.
None of the valves with the loose torque switch bolting demon-strated operability problems during operations or testing. The cause of the loose bolting appears to be consolidation or com-pression of the fibrous material and/or vibration.
Specific information regarding failure identification and correc-tive action taken are detailed on the enclosed Attachment 1.
Should further information be required, please contact Mr. Thomas Marlow, Superintendent of Ginna Support Services at 315/524-4446.

Twenty-six of 107 MOV actuators installed at R.E. Ginna Nuclear Power Plant contained SMA-type torque switches.            Torque switch material is a black, fibrous, laminated phenolic material.

Basic Components Affected:
Fourteen    safety related      MOV actuators    (five were non-safety      related).
Corrective Action: Immediate corrective action was to tighten the loose bolting. The torque switches are being replaced as scheduled,        during a Preven-tive    Maintenance      Actuator Refurbishment Program.      MOV actuators    are now on a three year    preventive      maintenance      inspection program for EQ operators, five year preventive maintenance inspection program for safety-related but not EQ and ten year preventive maintenance    inspection program for non-safety related actuators.

Notification of 10CFR, Part 21 R.E. Ginna Nuclear Power Station Docket No. 50-244 Licensee No. DPR-18

Dear Dr. Murley:

Rochester Gas and Electric is submitting the attached 10CFR, Part 21 Evaluation and Notification. The notification concerns a potential material defect of SMA type torque switches supplied by Limitorque during the late 1960's.

One hundred seven (107) of one hundred eight (108) motor operated valves (MOV) installed at R.E. Ginna Nuclear Power Plant, actuator wiring configurations were inspected in conjunction with an on-going Electrical Control Configuration Drawing Upgrade Project.

Twenty-six had SMA-type torque switches installed. The SMA-type torque switch is a black fibrous, laminated, phenolic material.

Ten of the twenty-six switches demonstrated loose one-quarter inch socket head mounting screws and nine of the twenty-six demonstrated loose wire termination bolts.

None of the valves with the loose torque switch bolting demon-strated operability problems during operations or testing. The cause of the loose bolting appears to be consolidation or com-pression of the fibrous material and/or vibration.

Specific information regarding failure identification and correc-tive action taken are detailed on the enclosed Attachment 1.

Should further information be required, please contact Mr. Thomas Marlow, Superintendent of Ginna Support Services at 315/524-4446.
