10 CFR PART 21 REPORT - NAMCO CONTROLS' LIMIT SWITCHES HAVE AN
IMPREGNATION SEALANT ANOMALY.
DURING A REVIEW OF A RECEIPT INSPECTION CLOSED PURCHASE ORDER, IT
WAS DISCOVERED THAT THE SUPPLIER WHO IMPREGNATED THE EA180
HOUSING DID NOT USE THE QUALIFIED SEALANT. THE LIMIT SWITCHES
AFFECTED WERE MANUFACTURED FROM 12/18/97 THROUGH 03/27/98. THE
IMPREGNATION SUPPLIER USED IMPREX 95-1000A WHICH WAS NOT
PREVIOUSLY QUALIFIED BY NAMCO CONTROLS. NAMCO USES IMPREX
95-500, BUT IT IS BEING DISCONTINUED DUE TO ENVIRONMENTAL
BENEFITS. IT HAS BEEN DETERMINED THAT APPROXIMATELY 112
IMPROPERLY IMPREGNATED HOUSINGS WERE SHIPPED TO NUCLEAR
CUSTOMERS.
