IMPROVEMENTS IN DEVICES FOR COOLING THE CONTROL RODS OF NUCLEAR REACTORS

Patent ·
OSTI ID:4008175
A method for gas cooling reactor control rods is described. The control- rod channel has a larger diameter in the center of the reactor than at the ends, so that more gas may circulate around the control rod. This bulge in the channel is needed because of the usually higher neutron flux and corresponding control rod heat evolution in the center of the reactor. A plug is provided such that raising the control rod to its highest position stops the flow of gas through that particular channel. (T.F.H.)
