Abstract

PURPOSE:To avoid an unstable area of an M-G equipment, and to execute an automatic operation extending over a wide range, by providing a bumpless manual/ automatic changeover device, and a fault detecting means of an unbalanced operation device, on a recirculating flow rate control device of an atomic reactor. CONSTITUTION:A speed request signal from a main controller 7 is sent to bumpless manual/automatic changeover devices 60A, 60B through an unbalanced operation device 9'. On the device 9' is provided a fault detecting function, and in the event of a fault of the device 9', a fault signal X is sent to the changeover devices 60A, 60B and the changeover devices are switched to manual control to automatic control. In case of both the manual and automatic control, the changeover devices make their output signals track each other, make the manual control system follow up to an automatic controlled variable in case of the automatic control, and make the automatic control system follow up to a manual controlled variable in case of the manual control. In this way, an unstable area of flow rate recirculating M-G equipments 12A, 12B is avoided, the equipments 12A, 12B are operated stably, each flow rate is increased or decreased, and the total flow rate is kept constant by control of the main controller.
