Abstract

PURPOSE: To reduce the output rising of the end of the control rods, by means of driving each indipendently by dividing a plurality of poison tubes within control rods into two group, and of withdrawing alternatively at the withdrawing time of control rods.
CONSTITUTION: A group poison tubes 1a and B group poison tubes 1b are lined up in a sheath. B4C is filled in one party of the poison tube, and an absorbing- effective poison against a higher energy nutron than thermal neutron is filled in another party. The poison tube 1a is fixed at the sheath, and the poison tube 1b is movable in the sheath to the longitudinal direction, and the lower end is combined by a combining tool 4. A group poison tube is connected to a driving axis 5, and B group poison tube is connected to a driving axis 6 outsided to the driving axis 5, and is drived independently, thereby the output rising of the end of the control rod can be reduced by means of withdrawing alternatively only one party of whichever when in the control rod withdrawing time.
