Conversely, when the reactor recirculation flow control device (RFC) 9 is in the automatic mode, the control rod operation monitoring device (RC & IS) 8 is put into the automatic mode after the reactor recirculation flow control device (RFC) 9 is in the manual mode. I needed to.

Therefore, a third object of the present invention is to provide an automatic output adjusting device which simplifies the operation procedure by eliminating the mode inputting operation of the control rod operation monitoring device and the reactor recirculation flow control device. .

There was a problem that the generator output (control rod) / (core flow rate) control at 14 was stopped and the control could not be continued.

Accordingly, a fourth object of the present invention is to perform control so as not to deviate from the operation range and to continue without stopping the generator output (control rod) / (core flow rate) control in the reactor power control device. It is an object of the present invention to provide an automatic output adjusting device.

Further, in the prior art, when the control by the control rods is performed, there is a problem that the fuel efficiency varies due to the repeated insertion and withdrawal operations of the control rods, resulting in poor efficiency.

Therefore, a fifth object of the present invention is to provide an automatic output adjusting device capable of eliminating a variation in combustion efficiency by selecting a control rod based on combustion efficiency.

In the prior art, a display with a touch screen (APR-FD) 11 which is a man-machine device is used.
For example, when a failure occurs, the operation state cannot be grasped, and the control by the automatic output adjustment device (APR) 13 cannot be continued.

Therefore, a sixth object of the present invention is to provide an automatic output adjusting device that continues the control by the automatic output adjusting device without stopping even if a failure occurs in the display of the man-machine device. .
