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.

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

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.
