ABSTRACT A method and system for maintaining forward flow direction and controlling the path of steam flow following trips of reheat turbines, by maintaining pressure differentials to control the direction ant path of the steam flow. After a turbine trip, pressure at the exhaust stage is reduced by extracting steam at a point just upstream of the exhaust and dumping it to a lower pressure zone, feedwater heater, or condenser. Additionally, pressure is increased at the inlet by introducing HP exhaust into the impulse chamber. Secondly, pressure is reduced on the concave, pressure side of turbine blading nearest the turbine exhaust by applying suction to steam collection channels running the length of the pressure surfaces thereof, thereby keeping the path of steam flow in contact with the pressure surfaces of the blades.
