IMPROVEMENTS IN AND RELATING TO FUEL ELEMENTS FOR NUCLEAR REACTORS

Patent ·
OSTI ID:4128227
A fuel element arrangement for graphite-moderated reactors is designed in which the canned fuel element is housed in, but spaced from, a graphite tube in such a way that a plurality of such elements can be stacked up in a channel without placing stress on the fuel or its canning; the stresses are taken up by the graphite tubes. The space between the moderator and the tube and the space between the tube and the element are open to coolant fiow. When the fuel elements are replaced, the graphite tubes can also be replaced; this is of advantage in CO/sub 2/-cooled reactors where graphite-CO/sub 2/ reactions can occur. The moderator is also kept at a low temperature level. (D.L.C.)
