摘要

摘要: 搜索堆芯临界棒位是反应堆堆芯物理设计的重要内容，传统的线性插值方法在搜索临界棒位时需要多次迭代，效率低、花费时间长。本文提出了一种基于控制棒价值函数的临界棒位快速搜索方法，得到了控制棒组价值与棒位的函数关系，并应用于三维堆芯中子学程序PBRT。通过与线性插值法对比发现，控制棒价值函数法搜索的临界棒位满足临界搜索收敛准则，搜索效率明显提高，是一种合理可行的快速调棒搜索临界方法。

Abstract: The critical rod position search of the core is an important part of the nuclear reactor core physical design. The traditional linear interpolation method needs much iteration when searching the critical rod position, which is inefficient and takes long time. A rapid critical rod position search method based on control rod value function was proposed in the paper. The function relationship between the control rod value and the rod position was obtained and applied to the 3D core physical code PBRT. Compared with the linear interpolation method, it is found that the critical rod position of the control rod value function method meets the critical search convergence criteria, and the search efficiency is improved obviously. It is a reasonable and feasible fast search critical method.
