flow can be used to control the reactor power in a broad range without movement of
control rods. BWRs can automatically follow the load requirements of the turbine,
by sensing pressure disturbances at the turbine, transmitting these signals to the
recirculation flow control valve and regulating core flow and therefore reactor
power.
In order to ensure high quality of the reactor feed water, all the feed water
recirculated from the turbine condenser is pumped through filters (demineralizer
units) and cleared of any corrosion products and other impurities.
