The problem of xenon poisoning is the target in this invention by Degussa in which the fuel elements are porous and uncompacted with at least 5% pore volume and exposed directly to the coolant. The elements may take several forms, all of large surface/volume ratio. Particularly recomnnended is a compound form made up of rods, disks or tubes, but any small shape giving a uniform and reproducible packing density is possible. Thus a graphite, beryllium, or zirconium container, which can fill the whole reactor chamber, is filled with either rods or such shapes as balls, Raschig rings, saddles, etc. In an alternative arrangement the container can be in the form of vertical tubes, filled with spherical fuel which can be continually charged and discharged. Suitable compounds for the fuel are oxides, carbides, silicides, or fluorides of uranium and plutonium.
