Reactor power was reduced in preparation for shut down. When the turbine was shut down, l                             reactor pressure increased and exceeded the high pressure scram setpoint, causing an automatic reactor shutdown, per design.
The Main Turbine operating procedure did not require reactor i                             pressure to be decreased to provide a sufficient margin between actual pressure and the high pressure scram setpoint prior to tripping the Main Turbine.
MARCH 26         2210   Shift began core unload.
I MARCH 30         1811   Shift completed core unload.
