Abstract

The minimise the escape of radio-active fission prods. in the event of a fuel element wall leak, plate type elements are made up of many uniform shaped pieces of fuel matl. each wrapped separately. Various methods of wrapping are proposed. The assembled pieces making up the fuel element are wrapped overall and a good heat-transfer bond achieved between fuel and cladding by high temp. fusion welding. E.g. with zirconium alloy cladding and ceramic fuel matl. the assembled element is heated for 4 hours at 830 degrees and 2,000 atm pressure in Helium. The internal wrapping is e.g. 0.4 mm and the main cladding 4 mm zircalloy.
