Core Configuration of the Syrian reduced enrichment fuel MNSR

ABSTRACT
 

The possibility of substituting the actual HEU by a LEU or MEU in the Syrian MNSR is investigated through a pre-constructed 3-D detailed model of the reactor. Core configuration does not change if a reduced enrichment fuel (20% u-235, with the same percentages of impurity and eliminating aluminum) is used. The required density for the reactor to be critical in this case would be 7.29 g/cm2. If a specific fuel is used (20 w/o U235, 72 w/o U ), the reactor may not go critical at all. When a MEU fuel is used (45 w/o U235, 40 w/o U ), the reactor will restore the same actual initial excess reactivity if 2 standard fuel rods are added to each fuel circle.
