| Title | Potential Failure to Comply with Specification Configuration |
| Event Description | Two Electroswitch P/N 70034K01 L-2 Auxiliary Switch Assemblies supplied to First Energy Perry Nuclear under purchase order #45151322 were taken from a spare parts inventory and were missing a spacer bushing (P/N 650311A39) that holds the rotary contact in position. First Energy Perry Nuclear reported this under OE25399. The absence of the bushing could allow the contact to move out of position, resulting in a loss of electrical contact. The presence or absence of the spacer cannot be determined from electrical or functional tests of the switch, because the electrical contact may not be displaced from its correct operating position.
The two nonconforming switch assemblies were not installed or placed in operation. Plant procedures require all switches to be opened and inspected prior to installation. ABB has taken or is taking action to quarantine and physically inspect all available on-hand inventory, notify all customers, revise dedication procedures, and review historical procurement and customer records. |
