Abstract
The core pile of a gas-cooled nuclear reactor is controlled by a plurality of absorbent graphite rods that are inserted into the pile according to a pre-determined pattern, the pattern being such that the density of distribution of the control rods over the cross-sectional area of the core pile is radially increased in the direction of the core periphery. By this control rod arrangement an overly severe concentration in the flow of neutrons on the periphery of the cord pile is avoided, and a more even distribution of neutron flow across the diameter of the reactor is obtained.
