| 中文摘要 | 用Monte Carlo方法计算了强中子注量通过较厚轻介质屏蔽层后在多层介质球中造成的温度分布。建立了包括源中子、屏蔽介质和多层球在内的简化几何模型,在源中子方向分别为矢径方向和球面外向各向同性分布两种模式下,用俄罗斯轮盘赌和分裂方法模拟了中子的深穿透输运过程,并采用指向概率方法,求得多层介质球内不同点的温度分布和介质平均温度。结果表明,在两种源中子方向模式下,同一介质不同位置的温度增量随该点离源的距离增大而减小,越内层的介质平均温度越高。; The temperature distribution in a multi-layer sphere composed light and heavy materials was calculated by using a neutron transport Monte Carlo method intense neutron irradiation that has traversed a thick light material.Simplified geometry model included neutron source,shielding materials,and multi-layer sphere.Russian roulette/splitting technique and point estimated method were used to obtain the temperature distribution in the multi-layer sphere,in the transportation under two neutron momentum distributions which are radius vector and isotropic.The results show that the temperature increment in the same material with distance increasing and that the inner layer average temperature is higher than the outer layer of the multi-layers sphere. |
