URANIUM-GADOLINIUM NUCLEAR FUEL AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2013 - IPC G21C3/00

Abstract RU 2502141 C1

FIELD: physics.

SUBSTANCE: method of making pelleted fuel for fuel cells involves preparing a doping composition containing 5…10% Al(OH)₃+30…40% Gd(OH)₃, the balance - UO₂, mixing uranium dioxide powder with a plasticiser and the doping composition in amounts which provide in the final mixture (moulding powder) content of Al(OH)₃ and Gd(OH)₃ of 0.5-2.0 wt % and 3.0-8.0 wt % respectively, moulding pellets from the obtained moulding powder and sintering.

EFFECT: obtaining pelleted fuel with uranium dioxide grain size of 30-50 mcm and with low content of open pores.
