CONTROL RODS FOR NUCLEAR REACTORS

Patent ·
OSTI ID:4759347
A means for controlling the control rod in emergency, when it is desired to shutdown the reactor with the shortest possible delay, is described. When the emergency occurs the control rod is allowed to drop freely under gravity from the control rod support tube into the bore in the reactor core. A normal shutdown is reached almost at the lowest rod position. In the shut-down position and also below it, the control rod had its full effect of reducing the level of activity in the core. When the shut-down position was reached, a brake came into action to decelerate the rod and reduce shock and the likelihood of damage. (C.E.S.)
