摘　　要：次临界装置安全、简单、操作方便,能完成大量的物理实验,适用于教学、培训和实验研究,但其具有不同于临界装置的特点。按照中-约次临界装置合同要求,针对该装置具体特点和实验研究需要进行了物理设计,确定了该装置主要物理参数,如优化的燃料棒尺寸、最佳慢化栅距、优化的堆芯布置方案等。在约旦科技大学完成的实验表明,设计结果与装置实际状况吻合良好。The subcritical assembly is safe, simple and easy to operate, and can be used to complete many physical experiments. It is suitable for education, training and experiment research, with its characteristics being different from those of a critical assembly. According to contract for design and construction of subcritical assembly, Jordan subcritical assembly （JSA） physics design was made to determine main physical parameters, such as optimal fuel rod size, optimal moderation lattice, optimal loading pattern, etc. The accomplished experimental results in the Jordan University of Science and Technology show that the physics design results and the actual situation of the assembly are in good agreement.
