METHOD OF NUCLEAR REACTOR CONTROL USING A VARIABLE TEMPERATURE LOAD DEPENDENT SET POINT

摘要

Case 4313 METHOD OF NUCLEAR REACTOR CONTROL USING A VARIABLE TEMPERATURE LOAD DEPENDENT SET POINT A method and apparatus for controlling a nuclear reactor in response to a variable average reactor coolant temperature set point (79) is disclosed. The set point (79) is dependent upon percent of full power load demand. A manually-actuated (85) "droop mode" of control is provided whereby the reactor coolant temperature is allowed to drop below the set point (79) temperature a predetermined amount wherein the control is switched from reactor control rods exclusively to feedwater flow.
