IMPROVEMENTS RELATING TO NUCLEAR REACTORS

Patent ·
OSTI ID:4132609
A fuel-element arrangement for gas-cooled graphitemoderated reactors is given in which each channel is not filled up to its capacity with elements but rather filled in such a way that, in a group of adjacent channels, only one element is present on one level and the next level's element is in a different channel than the first. The advantages of this arrangement are that less gas flow is required for the same fuel heat rating along with a smaller channel and that heat trsnsfer is improved for finned elements since the fins can then extend from the can to the channel periphery without obstructing the gas flow. The channels may either be formed in the moderator itself or in graphite blocks, which can be lifted out of the reactor together with their elements. (D.L.C.)
