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 DPRNS 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.~Back ouud In February 1997, D.C.Cook Plant notified Limitorque Corporation that an instaHed 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 Com onent 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.

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.Hylton Vice President-Engineering LIMITORQUE CORPORATION CLH/lab cc: Bill Friel Part 21 File Evaluation
