ある。As an example of the design of a steam generation system for a fast breeder reactor, there is a system using a separate once-through steam generator, which is conventionally known.
An example of a curved main steam temperature control method in this system is an evaporator outlet steam temperature control system shown in FIG. This control system controls the outlet steam temperature TO of the evaporator 1 and the feed water flow 11.
This is a control method in which the outlet steam temperature controller 7 operates the valve opening degree of the water supply valve 3 provided on the upstream side (that is, the inlet side) of the evaporator based on F, thereby changing the flow rate of the water supply.

数操作信号１５を出力する。The integral true flow type steam generator 11 has a structure and function that integrates the evaporator 1 and the superheater 2 in the conventional partial flow type steam generator shown in FIG. 1, and is a well-known one. The main steam temperature υ control system of the fast breeder reactor of the present invention has a transmission delay when the integrated once-through steam generator transfers the heat of the reactor (not shown) to the feed water via the secondary cooling 11. By focusing on the fact that the water flow rate is large, and taking advantage of this feature, the main steam temperature is controlled by increasing or decreasing the flow rate of the feed water by manipulating the rotational speed of the feed water pump 5. Additionally, the detectors used to detect the main steam temperature generally have poor response.
The main steam temperature deviates from a predetermined value when the plant output is changed, and in order to compensate for this, the feed water flow rate or the feed water pump rotation speed is used as an auxiliary signal. That is, 12 is the main steam temperature signal, 13i! The feed water flow signal 14 is a signal that does not indicate the rotation speed of the feed water pump, and the main steam temperature control system of the fast breeder reactor of this invention uses the main steam temperature signal 12 and the feed water flow signal 13, or the main steam temperature signal 12. The water supply pump rotation speed signal 14 is used as an input signal to the water supply pump rotation speed controller 10, and a water supply pump rotation speed operation signal 15 is output.

水ポンプ回転数が調整される。When changing the output, first, the feed water pump rotation speed is operated so that the feed water flow rate, which is a preceding signal, becomes a predetermined value, but it is gradually adjusted according to fluctuations in the main steam temperature, and finally In this case, the feed water pump rotation speed is adjusted so that the main steam temperature becomes a predetermined value.

Therefore, the water supply valve and all the control system equipment related to the water supply valve that were conventionally required can be completely eliminated, so the control system equipment can be reduced.
