Abstract

PURPOSE: To perform control rod operation obstruct at the first stop position enabling to stop by operating the control rod position pre-set for the control rod objective position set unit and the present control position detected with the control rod position detecting device when the control rod performs the error operation.
CONSTITUTION: Control rod 24 is driven by control rod driving unit 25 and stops at the position set by a signal transmitted from the operation board 26. The control rod stop position is detected with the control rod position detector 27, and indicated on the indicator attached to the operation board 26. The control rod position set to control rod objective position set unit and the present control rod position from the detector 27 are operated with the logical operator 28. In the process of the logical operation, the control rod operation obstruct signal is transmitted to the control rod operation obstruct unit 30 to stop the movement of control rod 24.
