>A reactor fuel element for hetetogeneous reactors is designed in which the neutron expense of a high cross section canning material is minimized. The element comprises a beryllia moderator hexagonal rod with uranium-containing plates inserted in recesses in each face and clad with stainless steel or chromized mild steel. A plurality of such elements may be held in a parallel relationship in a reactor by ceramic spacers at the corners of the hexagons. The advantages of this element design are that the thermal stresses in the moderator are reduced and that the coolant forces the can against the fuel inserts, providing good heat transfer to the can.
