为研究ADS散裂靶与反应堆的耦合特性,以及靶和缓冲区对堆芯反应性的影响,需开展实验研究,并对实验装置进行相应的堆芯物理设计。物理设计使用的计算程序为MONK9A,核截面数据库为ENDF/B-Ⅵ数据库。堆芯物理设计对开展实验研究至关重要,它既要满足实验任务要求,又要确保实验过程中的临界安全。因此,堆芯物理设计对实验研究能否达到预期结果具有重要意义。根据现有的核材料,进行了水慢化剂堆芯的物理设计,其堆芯结构如图1所示。为了在实验过
In order to study coupling characteristics of ADS spallation target and reactor, and the influence of target and buffer on core reactivity, experimental research is needed and the corresponding core physical design of experimental device is carried out. The physical design uses MONK9A, and the nuclear cross-section database is ENDF / B-VI. The physical design of the core is very important for carrying out experimental research. It not only meets the requirements of experimental tasks, but also ensures the critical safety during the experiment. Therefore, the physical design of the core is of great significance for the experimental research to achieve the expected results. According to the existing nuclear materials, the physical design of water moderator core is carried out. The core structure is shown in Fig.1. In order to experiment
