The maximum coolant temperature in the VVR-Ts MAK-2 loop facility for the production of 99Mo was analyzed. The calculations showed that adequate accuracy and temperature 96.3°C are attained using more than 106 grid elements. Taking into account the temperature dependence of the thermal conductivity of the uranium-containing layer increases the maximum temperature in this layer by more than 10%. When boiling, vaporization, and turbulence are taken into account the temperature at the egress from the coolant changes within the error range as compared with the use of a simplified model.
