FUEL ELEMENT FOR ATOMIC PILE AND METHOD OF MANUFACTURE
Patent
·
OSTI ID:4157626
A tubular fuel element, consisting of a zirconium tube provided with an external jacket of fissile material, is reported. The jacket is subdivided by means of radial perforated graphite interlayers and also provided with longitudinal and/or transverse slits; it is manufactured by induction melting fissile material around the tube. The construction of the fuel element prevents permanent deformation and localizes detachment of fuel from the tube during reactor operation. A number of these fuel elements are assembled in a graphite tube, the interstices being filled with graphite powder. This assembly is enveloped by an Al tube which is separated from the graphite tube by a heatinsulating layer.
