| Title | Part 21 Notification - Selector Switch Shorted Due to Incorrect Hardware |
| Event Description | The following information is summarized and was obtained from Curtiss-Wright via fax:
Curtiss-Wright was notified by Exelon Calvert Cliffs Plant that a Senasys selector switch P/N 910CMC-5240X (previously provided by Curtiss-Wright under Exelon purchase order 00630804), had failed a post-installation test. Calvert Cliffs sent the suspect switch to Exelon Powerlabs where the failure was found to have been caused by an assembly screw that was 1/8 inch too long, allowing it to cut into the coil of the switch, causing an electrical short. Correspondence between Exelon and the manufacturer determined that an inventory error had occurred. According to [Curtiss-Wright] records, only one customer and one plant received these defective switches. Exelon Generation's Calvert Cliffs received 5 switches on Exelon PO number 00630804 Rev. 2. Exelon Calvert Cliffs has been notified of this issue. Curtiss Wright's dedication plan will be revised to include a note to ensure no selector switches, for this part number, are manufactured with the November and December 2017 date codes. If you have any questions pertaining to this information, please contact Timothy Franchuk, Director of Quality Assurance, at 513-201-2176 |
