摘要
钍基熔盐堆是第四代核能系统重要的候选堆型之一,由于其堆型较新、堆体结构复杂,因此对屏蔽要求高,屏蔽设计工作难度较大。根据中国科学院上海应用物理研究所设计的10 MW固态燃料钍基熔盐实验堆的初步设计参数,使用基于蒙特卡罗方法的MCNP程序对熔盐堆堆本体进行了针对运行工况下的屏蔽设计与计算。此外,基于反应堆的设计运行过程状态,使用Scale程序的ORIGEN-S模块对反应堆的运行过程产生的放射性核素的量进行了计算分析,并使用基于点核积分方法的Scale程序的QADS模块对停堆后屏蔽体外的剂量率进行了计算。根据屏蔽计算结果和相应的设计要求以及国家法律法规的要求,初步确定了熔盐堆的堆本体辐射屏蔽系统结构。
As one of the candidates of generation Ⅳ nuclear energy system,thorium molten salt reactor is a new type of reactor having complex geometry structure.It requires shielding design work to provide shielding and protection for workers and equipment.Based on the design parameters of the 10 MW solid fuel molten salt reactor designed by Shanghai Institute of Applied Physics,China Academy of Sciences,shielding design work has been performed using Monte Carlo code MCNP and point-kernel code QADS module of Scale for normal operation and shutdown,respectively.The source of reactor shutdown was obtained with the ORIGEN-S module of Scale code.The structure of the primary shield was determined according to the calculation results and the regulations of national authorities.
