摘要： PURPOSE:To maintain the thermal efficiency of a nuclear power plant by varying the flow rate of steam which is fed to a supply water heater according to the temperature of feed water so as to regulate the temperature of the water which is fed to the steam generator within the specified range. CONSTITUTION:The temperature of feed water which passed through feed water heaters 8a and 8b and is to go into a pile 1 is detected by a temperature detector 15. Based on the difference between the detected value and the set value of a temperature, controlling arithmetic operation such as PID or so is performed in a temperature regulator 16, which issues the control signal to control a regulation valve 10a or 10b. The signal of a steam flow detector 17 which measures the quantity of steam generated from the pile 1 is sent via a function generator 18 to the temperature regulator 16 to fix the set value of the temperature dependently on the quantity of the evaporated steam. The necessity of increasing the temperature of feed water more than needed may be avoided and the consumption of steam be therefore reduced, on account of which the temperature of feed water can be regulated without any reduction in thermal efficiency of the plant.
