Taleyarkhan, R P

In a nuclear fuel assembly including an outer hollow tubular flow channel for directing the flow of coolant/moderator fluid through the fuel assembly and a hollow water cross extending through the channel and attached along the interior of the channel so as to divide it into separate compartments and provide a central hollow channel for flow of coolant/moderator fluid through the fuel assembly, a hybrid fuel design is described comprising: (a) cladded rod-type nuclear fuel located within the compartments spaced from the outer channel and the water cross; and (b) cladded plate-type thermally fissile nuclear fuel attached on the exterior of the water cross for distributing power generation between the cladded rod-type nuclear fuel and the water cross.
