| event text = On March 23, 2017, at 0014 EDT, Watts Bar Nuclear Plant Unit 2 (WBN2) experienced an unplanned trip of both Turbine Driven Main Feed Pumps (TDMFP) following a loss of Main Condenser Vacuum. The trip of both TDMFPs caused an automatic start of both Motor Driven Auxiliary Feed Water Pumps and the Turbine Driven Auxiliary Feed Water Pump. [The] cause of the loss of Main Condenser Vacuum is currently under investigation.
The plant was performing a normal startup, and had just synced the main generator to the grid. Subsequent to the event, the plant was transitioned to Mode 3. All rods are fully inserted. Decay heat is being removed via the atmospheric relief valves.
Unit 1 remains in Mode 5 for a refueling outage.
The licensee has notified the NRC Resident Inspector.
