Document Type and Number:
Japanese Patent JP2006189290
Kind Code:
A
Abstract:

To provide a control rod driving control device capable of driving one or a plurality of control rods simultaneously by utilizing an existing facility, and securing reliability similar to the state before being changed.

A control rod to be inserted or extracted is selected from among control rods for performing output control of a reactor by a control rod selection circuit 14. A control rod driving control circuit 16 supplies driving water to a piston of a control rod driving mechanism, to thereby control opening/closing of a control valve performing insertion/extraction operation of the control rod, in response to an insertion/extraction command to the control rod selected by the control rod selection circuit 14. The flow rate of the driving water loaded when performing the insertion/extraction operation of the control rod is assigned beforehand to each of a plurality of common or waiting stabilizing valves, and a stabilizing valve combination selection circuit 15 secures the flow rate of the driving water by combining the common or waiting stabilizing valves corresponding to the insertion/extraction operation of the control rod 1 selected by the control rod selection circuit 14.
