Description
At 0649 (EDT) The VC Summer Nuclear Statio … At 0649 (EDT) The VC Summer Nuclear Station automatically tripped due to a turbine trip. The cause of turbine trip is under investigation. Preliminary review indicates a possible failure of one phase of the main generator breaker. The three emergency feedwater pumps automatically started on Lo-Lo steam generator level. Preliminary review indicates all primary and secondary systems responded as required.</br>The plant is in mode 3 with normal RCS pressure and temperature. Decay heat is being removed by dumping steam to the condenser. The station will remain in mode 3 until repairs are complete. Estimated restart date has not been determined.</br>All control rods fully inserted. The plant is in a normal post-trip electrical lineup with the exception of the balance of plant buses which are on the alternate electrical source.</br>The licensee will inform State and local agencies and has informed the NRC Resident Inspector.d has informed the NRC Resident Inspector.  +
