ABSTRACT:
A nuclear fuel element is fabricated from a porous graphite block containing a plurality of open coolant passageways and a plurality of fuel chambers uniformly located therebetween. The fuel chambers are filled with nuclear fuel material and closed. The entire porous block is then impregnated with a liquid carbonizable impregnant which penetrates through the septa and into each of the fuel chambers, wherein it is cured and then carbonized in situ. The resulting carbon residue integrally binds the nuclear fuel material to the fuel chamber walls of the porous graphite block and provides excellent heat transfer from the fuel to the walls of the open passageways from which the heat is extracted by the coolant.
