Fortescue, P; Lockett, G E

A reactor fuel element is designed comprising sleeves of fuel mixed with graphite inserted into annular recesses in a cylinder formed by a graphite tube and a graphite rod. The sleeves may contain approximately 1 atom in 1000 of fissionable material and may be formed by cold-compacting a mixture of powdered graphite and fissionable material in a manner described by patent No. 850,016. Since heat is transferred from the sleeves to the container by radiation, there is no need for a close fit between the sleeves and the container, and distortion of the fuel is permitted. A core built of such elements consists of seven- element clusters secured to graphite spiders in a way that a plurality of clusters may be built up in parallel. Ducts for venting the interior of the elements ans provided in order to remove volatile fission products. (D.L.C.)
