| 摘 要： | 在基于三维蒙特卡罗方法的聚变装置停机剂量率计算方法“严格两步法”(R2S)的基础上,首先建立了核聚变托卡马克实验装置HT-7U三维精确模型,然后对HT-7U各种D-D放电模式下的停机剂量率进行了详细的三维计算与分析,从而为装置实验方案及实验维修人员的安全操作规程的制定提供了理论基础,也对装置的辐射防护问题具有参考价值。

| Abstract: | Based on "R2S(Rigorous 2-Step)" method, which enables 3-D Monte Carlo analysis ofshutdown dose rate for nuc1ear fusion device, a realistic Monte Carlo 3-D model of HT-7U devicewas developed and then comprehensive calculations and analyses were performed for different dis-charge modes of HT-7U. The results were expected to provide theoretical basis for the creation ofoperational scenario and regulations for safe operation by experimental and service personnel,alsoto give indication for radiation shielding of HT-7U. |
