    • PURPOSE:To stably control a water level of a drainage tank by changing a drainage water-level set value when a drainage water-level rises to the upper limit of a normal control range and changing the set value to a water level set value before the change when the water level becomes a reference water level or below. CONSTITUTION:By adding a water level signal 10 of a normal water level detector 9 to a water level signal 14 of an emergency use water level detector 13, a water level signal 21 corresponding to a wide range water level detector is calculated. By allowing this water level signal 21 to pass through a hysteresis 22, water level setting 23 of an emergency use water level control system is given, and a water level deviation signal 24 is calculated. Also, this signal is allowed to pass through a limiter 25, an emergency use control range is prescribed, and thereafter, by an emergency use control system 15, a linear PID operation is executed. In this case, Lu denotes a value corresponding to the upper limit water level of a normal water level control system 15. A limiter 26 gives a saturation characteristic to an output of the emergency use control system 15, and allowed to have an integral rest wind-up operating function of a PID operation. When a real water level is within a normal control range, a water level set value of the emergency use control system 15 is 2Lu, and a bypass holds a fully closed state.

    • PURPOSE:To obtain an output controlling device with a quick respondence enough to keep a stable operation by suppressing an excess increment of neutron flux during an output change operation and by preventing a nuclear reactor scram therewith. CONSTITUTION:An adjusting valve for a turbine steam is controlled by an output signal of a pressure control system 22 adjusted by a deviation signal between a neutron signal and a standard signal. A load deviation signal is obtained by the deviation signal and accumulators 32e and 32f, and a pressure setting point is regulated by the load deviation signal, a regulating circuit 21 for the pressure setting point and accumulators 32b and 32c. Moreover, an MG set is controlled by the load deviation signal adjusted by a feed-forward circuit 27, and by a main controller 16, a velocity controller 17 and 18 and by a position regulator 20 for a scooping tube, and also a recirculation pump velocity is controlled to regulate a recirculation flow rate. An adjuster 30 is constituted with a filter 31, an accumulator 32a to obtain a deviation between the neutron signal and the standard value, a limiter 33 and a hysteresis filter 34.
