Production of nuclear fuel products
Creators
Description
A method is described of producing fissionable nuclear fuel pellets containing uranium dioxide, consisting essentially of the steps of: (a) admixing particulate uranium dioxide nuclear fuel with a fugitive binder comprising a combination of about 1 part by weight of high molecular weight acrylic acid polymer having an average molecular weight of at least about 400,000 and about 4 to about 8 parts by weight of ammonium bicarbonate; (b) forming the resultant admixture by pressing into a coherent compact; and (c) sintering the resultant admixture of the particulate uranium dioxide with acrylic acid polymer and ammonium bicarbonate fugitive binder formed into a compact to expel binder material and integrate the particulate uranium dioxide nuclear fuel into a uniform body
