A preliminary feasibility study has been performed for HEU (UAlx) and LEU (UMo dispersed) fuels with various combinations of burnable poisons . Reactivity perfo r- mance, control rod motion, cycle length and fuel burn up (GWD/MTU) prior to discharge are compared in order to assess the fuel utilization. It has been found that the economy of the fuel cycle is significantly improved by using gadolinium poison in a form of homogeneous mixt ure with the fuel meat. At the same time, the experimental performances for gadolinium are similar as for the standard poisons (boron and samarium) used in the standard BR2 HEU fuel type .
