Abstract: The electrical power output of a nuclear powered generating station, as requested by an operator or by an automatic dispatch system for the grid with which the station is associated, is controlled in a manner which insures that the nuclear steam supply system limits are not violated. The invention permits the nuclear powered generating unit to operate at maximum permissible power for the existing nuclear steam supply system conditions by exercising control over the unit turbine in such a manner that the rate of load change will be controlled as a function of the proximity of the actual load to the desired load and the rate of load increase will be algebraically limited by the proximity of the nuclear steam supply system conditions to the steam supply system operating limits. Additionally the turbine load will automatically be reduced when necessary at a rate which equals or exceeds a value which is commensurate with the magnitude of any violation of the steam supply system operating limits.
