| titleOfInvention | Method for preparing a powder comprising particles of triuranium octoxide and particles of plutonium dioxide |
| abstract | The invention relates to a method for preparing a powder comprising an intimate mixture of U 3 O 8 particles and PuO 2 particles and which may further comprise particles of ThO 2 or NpO 2 . The method comprises: a) preparing, by oxalic precipitations, an aqueous suspension Si of particles of uranium(IV) oxalate and an aqueous suspension S2 of particles of plutonium(IV) oxalate; b) mixing the aqueous suspension Si with the aqueous suspension S2 to obtain an aqueous suspension S 1+2 comprising particles of uranium(IV) oxalate and particles of plutonium(IV) oxalate; c) separating the aqueous suspension S 1+2 into an aqueous phase and a solid phase comprising the particles of uranium(IV) oxalate and the particles of plutonium(IV) oxalate; and d) calcining the solid phase to convert (1) the particles of uranium(IV) oxalate to particles of triuranium octoxide and (2) the particles of plutonium(IV) oxalate to particles of plutonium(IV) dioxide, whereby the powder is obtained; and and in that steps b) and c) are performed simultaneously or successively. Applications: fabrication of nuclear fuels of MOX type, e.g. for LWR or FNR reactors. |
