The failures would remain in the operated/energized contactstate with power removed for some period of time. All starters impacted with this failure were continuouslyenergized. The concern was that if tripped, that the main contacts would not open to protect the motor."Testing was performed by Eaton Industrial Controls Division after receiving defective samples from PGE. TheTest Report from Eaton was received by QTNP for further review and evaluation. On October 6, 2015 QTNPdetermined that the Cutler Uammer A200 series starter failures may be reportable and an extent of conditionreview needed to be done."The root cause was a silicon based mold release that remained on the molded parts and would come betweenthe moving (magnet) & fixed armatures. When heated for an extended period of time, this material would becomesticky causing anywhere from a minor delay in opening, up to a frozen closed condition."Cutler Hammer has determined that the silicone mold release was first introduced into the manufacturing facilityin May 2008 due to a shortage of the Zinc Stearate Mold release that was tr'aditionally used. The silicon basedmold release was periodically used until October 2012. According to Cutler Hammer, anything made after January1, 2013 should definitely be silicon mold release free."Thus any starters/contactors of the CH A200 series manufactured between May 2008 & December 31 , 2012could have this concern. This failure has only been reported for continuously energized applications. The end user 12/18/2015 U.S. Nuclear Regulatory Commission Operations Center Event Report Page 2should evaluate their applications for this potential failure mechanism."QTNP has notified North Anna, H.
