OSTI ID:4085470

In order to get a substantially linear relationship between the reactivity and the position of the control rods, these rods (movable in a vertical direction) are grouped in such a manner that the channels of the respective groups lie at the corners of concentric polygons. Equipment is provided to move the rods of the same group simultaneously and independently of the rods of the other groups. The movement of the groups is performed successively, e.g., in such a manner that first the rods of the outermost groups are raised and then those of the succeeding groups; the rods are lowered in exactly the reverse order, viz., first those of the innermost groups and then successively those on the outside. The movement of a succeeding group begins before the movement of the preceding group is ended. (NPO)
