PART 21 REPORT - DEFECTIVE FUSES
The following information is a synopsis of information received via E-mail:
"On February 20, 2016 United Controls International issued a Return Material Authorization (RMA) request to First Energy - Perry Nuclear Power Plant. The RMA was issued to request the return of general purpose fuses of part number OT15 that were provided to First Energy - Perry Nuclear Power Plant under purchase order 45225736. The customer identified a fuse that had intermittent electrical continuity during resistance checks. The customer performed an evaluation which included dissection of the subject fuse and the cause of the issue was identified as being due to a lack of or inadequate solder connection of the fuse element to the fuse ferrules.
