AUTOMATIC REACTOR SCRAM FROM 100% POWER DUE TO A TURBINE/GENERATOR TRIP 

"Actuation of RPS [Reactor Protection System] with reactor critical. The Reactor Scram occurred at 1805 [CST] 01/14/13 from 100% CTP [Core Thermal Power]. The cause of scram appears to be a Turbine Generator Trip. 

"05-S-01-EP-2 RPV Control, Reactor Scram ONEP [Off Normal Event Procedure] 05-1-02-I-1, and Turbine and Generator Trips ONEP 05-1-02-1-2 were entered to mitigate the transient with all systems responding as designed. No loss of offsite or ESF power occurred. No ECCS initiation signals were reached and no ECCS or Diesel Generator initiation occurred. 

"All control rods are fully inserted. MSIVs remained open and SRVs lifted and reseated as designed. Currently, reactor water level is being maintained by the Condensate and Feedwater system in the normal band and reactor pressure is being controlled via Main Turbine Bypass valves to the main condenser. There are no challenges to Primary or Secondary Containment at this time." 

The licensee notified the NRC Resident Inspector.
