考虑到中子输运的屏蔽，满足距离屏蔽体最外面2.5m处中子+光子剂量率小于200 mRem/h（2 mSv/h）为约束条件，根据任务书中规定的材料，针对车载反应堆，受限于标准集装箱2.35米宽度，侧面外层屏蔽可采用可拆卸式结构

Considering the shielding of neutron transport, the constraint condition is that the neutron+photon dose rate at a distance of 2.5m from the outermost shielding body is less than 200 mRem/h (2 mSv/h). According to the materials specified in the task book, for the vehicle mounted reactor, limited by a standard container width of 2.35 meters, the outer side shielding can be a detachable structure.
