PROBLEM TO BE SOLVED: To increase the electric output of a reactor while curbing both the quantity of generated main steam and the decrease in the design freedom of a main steam system in the increase in the thermal output of the reactor in a nuclear power plant. SOLUTION: In a nuclear power generation system, the thermal output of the reactor is increased by boosting the quantity of the energy (generation) recovered in a low-pressure turbine through the increase in the quantity of the steam entering the low-pressure turbine while the steam extracted from a midpoint in a high-pressure turbine is reduced selectively and the heating amount of the feed water heated by the extracted steam of the main steam is decreased to curb the increase in the flow rate of the main steam by lowering the enthalpy (temperature) of feed water.
