Use schematic diagrams to draw the flow path of both a BWR and a PWR. Explain the flow path in the reactor core for both types of reactors and the flow path in the steam generator of the PWR.
During normal operation of a PWR, feedwater enters the secondary side of the steam generator. After being heated by the hotter primary side water, feedwater boils in the tube bundle and dry steam leaves the steam generator and flows towards the turbine through the main steam line. In this condition, water level in the steam generator remains at a fixed level. Is it fair to say that the flow rate of steam out of the steam generator exactly matches the flow rate of the feedwater into the steam generator?
