The quality at the rear end of the heat generation of ordinary fuel rods is larger with the high-output fuel assembly and if the same flow rate is passed in both, the pressure drop is larger in the high-output fuel assembly and eventually the flow rate of the high-output fuel assembly decreases. Since there are no fuel rods 10a in the upper part of the high-output fuel assembly, the fluid pressure drop in this part decreases and eventually the entire pressure drop of the fuel assembly decreases and the flow rate increases. The fuel rods 10b are long and the quality in the fuel assembly outlet is higher so that the larger steam quantity is obtainable with the low- output fuel assembly.
