Abstract
PURPOSE:To obtain a nuclear reactor of which the core power can be controlled by means except control rods and which can improve the responsiveness of the power and decrease the load to fuel by injecting part of feed water into the reactor from a feed water port provided in the lower part of the reactor core by a force circulation function. CONSTITUTION:The feed water flows at a constant ratio to a feed water supercharger 6 in the upper part and the feed water port 8 in the lower part of the reactor core during the stationary operation before the load increases. A flow rate control valve 13 for the feed water in the lower part is automatically increased in the opening degree if the load is assumed to increase at this time. Then, the flow from the feed water port 8 increases and the force flow increases. The reactor core power increases on increasing of the core flow rate. The flow rate of the feed water port 8 decreases and the power decreases with a decrease in the turbine load. The dealing with the power of the nuclear reactor as against a change in the load can thus be executed by the opening and closing operations of the valve without moving the control rod and, therefore, the response speed thereof is high. Since the reactor power can be changed by the change in the core flow rate, the load to be applied to the fuel is decreased.
