| 摘 要： | 核反应堆的温度分布计算在核反应堆的安全设计中十分重要.我们利用MCNP计算的线功率密度带入MATLAB编写的单通道模型热工程序,配合热工计算得到的冷却剂密度分布调整MCNP的模型重新计算,能够将堆芯物理计算和热工计算进行结合,得到了更为准确的单通道温度分布、功率分布及热管因子.

| Abstract: | The calculation of the temperature distribution of nuclear reactors is very important in the safety design of nuclear reactors.This paper uses MCNP calculated linear power density and puts it into the single-channel model programmed by MATLAB,then re-calculates the MCNP model by using the coolant density distribution which is calculated in the MATLAB.Combining core physicals with thermal-hydraulics,In the end,it can get more accurate single-channel temperature distribution,power distribution and hot channel factors. |

| Keywords: | MCNP MATLAB temperature distribution density distribution single-channel model |
