… The following was received via facsimile:</br>Allen Bradley relay base model 700RTC contains an unevaluated CPLD (Complex Programmable Logic Device). This was an unpublished design change that did not result in a part number change from Allen Bradley. There was no change to the appearance of the relay that would identify any design changes made to the relay configuration. Allen Bradley has indicated that the change occurred in mid-2009 and that it was a rolling change with no specific manufacturing date to distinguish between the old and new configuration. Based on this information, all units manufactured during 2009 and later are suspect.</br>Nutherm International, Inc. has concluded its review of all procurements of the 700RTC series relays and have found two (2) units manufactured during or after 2009 dedicated and shipped to customers. The following facility was determined to be impacted by this condition:</br>Utility: Exelon</br>Plant: Quad Cities</br>Purchase Order: 00447625</br>Part Number: 700-RTC11110U1</br>Nutherm Traceability Number: 11340-02R01 1/01, 11340-02R01 1/02.</br>In a separate 10CFR Part 21 notification, Event Number 51095, reported to the NRC (on) 5/28/2015 indicated that the CPLD can be affected by electrical noise from operation of nearby relays which can reset the timing of the relay. The plant should evaluate whether the installed relays are subjected to unevaluated EMI/RFI (electromagnetic interference/radio-frequency interference) conditions when installed in the plant.e) conditions when installed in the plant. +
