The maximum coolant temperature in the VVR-Ts MAK-2 loop facility for the production of 99 Mo was analyzed. The calculations showed that adequate accuracy and temperature 96.3°C are attained using more than 10 6 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.

MAK-2 设施中最高燃料和水温的热工水力计算

分析了用于生产 99 Mo 的 VVR-Ts MAK-2 回路设施中的最高冷却剂温度。计算表明，使用超过 10 6 个网格元件可以获得足够的精度和 96.3°C 的温度。考虑到含铀层的热导率的温度依赖性，该层中的最高温度增加了 10% 以上。当考虑沸腾、汽化和湍流时，与使用简化模型相比，冷却剂出口处的温度变化在误差范围内。
