On April 14, 2017 at 13:57 while attempting to transfer the 2C 4 Kilovolt (kV) vital bus from 24 Station Power Transformer (SPT) to 23 SPT, the 24 SPT infeed breaker opened properly but 23 SPT infeed breaker failed to close.
The 23 SPT infeed breaker failing to close as expected resulted in de-energization of the 2C 4kV vital bus and subsequent start and loading of the 2C Emergency Diesel Generator (EDG) to power the bus.
This report is being made in accordance with 1 OCFR50. 73 (a)(2)(iv)(A), "Any event or condition that resulted in manual or automatic actuation of any of the systems listed in paragraph (a)(2)(iv)(B)," for this event actuation of the 2C EDG.
Notification of this event was provided via ENS 52681 NRC FORM 366 (04-2017)

CORRECTIVE ACTIONS
- The 23 SPT infeed breaker to the 2C 4kV bus was replaced
- The 52/IS switches from the 22 Containment Spray pump (CS) and the 23 SPT infeed breaker to the 2A 4kV bus have been replaced and the removed switches will have internal inspections performed for extent of condition inspection.
- Any additional corrective actions will be determined after the switch inspection results are received.
