Method of controlling the power output of a nuclear reactor.

摘要

The power output of a nuclear reactor is controlled in response to a variable average reactor coolant temperature set point (79). 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.
