以某型乏燃料运输容器为计算模型,分别利用SCALE5.1程序系统中的一维离散纵标法程序和三维蒙特卡罗方法程序对运输容器进行了屏蔽计算,计算结果表明,两种方法的总当量剂量率结果相对偏差在10%以内。最后对两个模块的应用特点及差异进行了比较分析,为其在乏燃料容器屏蔽计算中的应用提供参考。
Taking a spent fuel shipping cask as calculation model, detailed shielding calculations were performed using one-dimensional discrete-ordinates code SAS2 and three-dimensional Monte Carlo method code SASd in SCALE 5.1 code system. Results show that the total dose rate calculated by the two methods accords with each other well and the relative error is less than 10%. Finally the two methods were comparatively analyzed in characteristics and difference, which provides references for their applications in spent fuel cask shielding calculations.
