Nuclear Regulatory Commission Washington, DC 20555 ATTENTION: Document Control Desk SUBJECT: Follow-up advisory for 10 CFR Part 21 defect reported by American Electric Power REFERENCE: Donald C. Cook Plant, Units 1 and 2 Docket Numbers 50-315 and 50-316 Operating Licenses DPR-58 and DPR-74 Pursuant to the requirements of Title 10 Code of Federal Regulations Part 21 herein contained is a follow-up advisory of a defect in a basic component. The initial notification of this has been previously reported by American Electric Power - Donald C. Cook Plant. This advisory is being made to all utility end users and the commission at the same time to expedite the process. Background In February 1997, D. C. Cook Plant notified Limitorque Corporation that an installed SMB-00 actuator had failed to operate. At that time D. C. Cook officials identified the double pole torque switch as the root cause of that failure. Basic Component Affected The double pole torque switch shown in Figure 1, installed in SMB, SB, and SBD actuators, has been identified as the defective basic component. Limitorque Corporation P. O. Box 11318 5114 Woodall Road Lynchburg, VA 24506-1318 Tel. (804) 528-4400 FAX (804) 845-9736 Page 2 April 22, 1997 Part 21 Notification Part Numbers: Unit Size Standard Nuclear 00 11500-011 11501-012, 11500-160, 11500-012 0 11500-019 11501-020, 11500-020 1 11500-027 11501-028, 11500-028 2 11500-035 11501-036, 11500-036 3 11500-043 11501-044, 11500-044 4 11500-051 11501-052, 11500-052 5 11500-059 11501-060, 11500-060 NOTE: The above part numbers may not be applicable for Double Pole Torque Switches procured for actuators manufactured prior to 1975. In this case, Figure 2, can be used for visual identification of the torque switch. Figure 3 depicts the standard torque switch assembly, this is shown below the double pole torque switch. The standard torque switch is not affected, and not subject of this advisory. Nature of the Defect The defective assemblies are missing a spacer between the torque switches, shown in Figure 2 and shown below the double pole torque swtich in Figure 1. The affected switch is the outboard assembly (i.e. the switch furthest from the lever arm). The torque switch contacts open prematurely resulting in either incorrect indication of output torque delivered or deenergization of the actuator motor prior to the valve achieving full travel. The aforementioned results are dependent upon the electrical control circuit that is utilized. The malfunction should be detected during initial actuation setup. It should be noted that the inboard assembly (i. e. the switch closest to the lever arm) is not affected and will function properly. Corrective Action Limitorque has instituted an additional inspection check of double pole torque switches to detect any assembly error and correct any defect prior to shipment. Licensee corrective action must include reviewing all installed and in- stock torque switches to determine if any double pole torque switches exist in inventory or are installed. Once identified, the licensee must visually examine each for the presence of the subject spacer, and Page 3 April 22, 1997 Part 21 Notification replace any torque switches which are missing the spacer. Defective torque switches may be returned to Limitorque for repair and replacement. The Limitorque contact for returns is Jim Hammer, Product Reliability Manager, at Ext. 9863. Any questions regarding the above advisory may be directed to Mr. P. McQuillan, Nuclear and Special Projects Manager at Limitorque (804) 528- 4400 Ext. 9714. Signed: Charles L.
