TLL 017 ITEM 1.
Determine if your facility has installed or plans to install NAMCO EA180 switches in any safety-related equipment located inside or outside containment, including valve position indicating circuitry related to containment isolation valves.
RESPONSE
1.
The TMI facility does not have any NAMCO EA180 switches installed in any safety-related equipment located inside or outside containment.
As an additional precaution we checked with our stores group.
Their records indicate that no orders were received from NAMCO during the period of February 1979 through August 1979.
