ABSTRACT:
A method of controlling a nuclear power generating station in the event of a malfunction of particular operating components which minimizes the number of hypothecated occurrences where tripping the reactor might become necessary. Upon identification of such a malfunction, preselected groups of control rods are fully inserted sequentially until a predetermined power level is approached. Additional control rods are then selectively inserted to quickly bring the reactor to a second given power level chosen to be compatible with safe operation of the system with the malfunctioning component. At the same time as the thermal power output of the reactor is being reduced, the turbine is operated at a rate consistent with the output of the reactor. Thus, in the event of a malfunction, the nuclear power generating system is operated in a turbine following reactor mode, with the reactor power rapidly reduced, in a controlled manner, to a safe level compatible with the type of malfunction experienced.
