IMPROVEMENTS RELATING TO CONTROL EQUIPMENT FOR NUCLEAR REACTORS

Patent ·
OSTI ID:4124074

A control system for graphite-moderated reactors is described in which the control mods are moved in groups of two or three each, each group commencing to lift when the previous group has reached either the full extent or half the extent of its travel. In this way, the reactor can be made critical as quick1y as possible without loss of control. The system contains a low-frequency a-c voltage generator and separate positional motors of the synchronous type for the control rods. Complete details on the corection of the generator to the positional motors are given. (D.L.C.)
