The cause of the turbine trip is not known at this time. The scram was not complex, with systems responding normally post-scram.</br>Operations responded and stabilized the plant. Reactor water level has been recovered and maintained at the normal level. Decay Heat is being removed by the Main Steam system to the main condenser using the Turbine Bypass Valves.
