摘要
在一维几何模型的基础上采用 ANISN程序,计算并分析了 HT— 7U超导 Tokamak在 D—D放电时周围环境辐射剂量当量率的变化规律,计算与分析的结果可供Tokamak核聚变实 验装置作环境评价和防护设计参考。
Calculation and analysis on radiation field around HT-7U Tokamak device under the condition of D-D discharge have been performed with the one dimensional discrete ordinate transport calculation code ANISN. The effects of concrete wall and borated water with different thicknesses on shielding have been analyzed. The spatial distribution of fluxes of neutrons and induced photons and dose rate equivalent can be used as a reference to the radiation protection design and environmental asscessment of HT- 7U device.
