Kinetic parameters of a material test research reactor fueled with high density U3Si2 dispersion fuels
چکیده انگلیسی

The kinetic parameters of a material test research reactor fueled with high density U3Si2 dispersion fuels were calculated. For this purpose, the low density LEU fuel of an MTR was replaced with high density U3Si2 LEU fuels currently being developed under the RERTR program. Calculations were carried out to find the core excess reactivity, prompt neutron generation time and effective delayed neutron fraction. Nuclear reactor analysis codes including WIMS-D4 and CITATION were employed to carry out these calculations. It is observed that the excess reactivity (Δk/k  ), prompt neutron generation time (μs) and effective delayed neutron fraction at the beginning of life followed the relationships 0.05403+0.00286ρU−(0.92958/ρU2), 106/(922.338+5268.82ρU−70.863ρU2) and (7.2165−7.238×10−3ρU)/1000(7.2165−7.238×10−3ρU)/1000, respectively, for 4.0≤ρU(g/cm3)≤6.04.0≤ρU(g/cm3)≤6.0.
