| 摘 要： | 本文根据严格二步法的计算理论,研究了基于网格计数的停机剂量率计算方法,设计并实现了基于网格计数的停机剂量率计算程序。该程序能够支持圆柱坐标下的网格计算。本文使用源子程序进行复杂源描述。为了加快计算速度,本文采用了多节点和多线程等技术。本文利用国际热核聚变实验堆(ITER)停堆剂量基准实验ITER-T426进行测试,计算结果与实验值吻合良好,证明了该方法和程序的正确性和可用性。

Rigorous Two-step Shutdown Dose rate Calculation Method Based on Mesh Tally |
| |
| Abstract: | Based on the computation theory of rigorous two-step,a shutdown dose rate calculation code utilizing mesh tally technique was developed.This code supported cylindrical mesh.It integrated a source subroutine which could provide sources sampling from repeated structures geometry.Additionally,based on the platform of multi-core blade server,multi-node and multi-thread technique were adopted to conduct the mesh material and inventory calculations.The verification test was conducted on ITER-T426 experimental benchmark.The results were in good agreement with the experimental values,which proved the validity and reliability of this method and code. |
