Ludbrook, L C; French, P R.J.

An improved arrangement of control rcds is proposed for controlling a reactor which gives a nearly linear relationship between the reactivity and the positioning of the control rods. The rods are arranged in groups forming a plurality of concentric circular loops which are raised or lowered independently, with all rods in one group moving simulthneously. The movements of the groups are overlapped so that each group after the first commences to move when the preceding group is at the mid-part of its travel. This overlapping gives a linear reactivity vs position (or time) relationship. Control rods are actuated by a motor powered by cam-fed rectified current. Both the circuitry of the control apparatus and the sequence of operations are given. (D.L. C.)
