It presents an approach to integrated design of runner system based on feature, CAE and artificial intelligence techniques. The approach covers all the aspects of the runer system design.

提出了全面考虑流道系统设计的各个过程，基于特征、CAE和人工智能技术对流道系统进行集成设计的方法，以克服单一设计方法的不足。

In actual reactors, the cooling condition outside the hexcan-wall of blocked fuel subassembly is analogous to its counterparts in the SCARABEE BE+ experiments. The upward and downward heat transfer could be neglected, while the radial heat transfer plays a key role in slowdown the accident scenario. As time goes on, the dominant radial heat transfer mechanism is liquidus sodium convection at first, and then gradually transforms into sodium condensation near the inner surface of the hexcan-wall, and finally becomes volume heated boiling pool convection.

对实际快堆中发生全堵的燃料组件而言，其外部的冷却条件与SCARABEE BE+系列实验非常相似；2）堵流组件向上和向下的传热可忽略不计，径向传热对事故有较强的延缓作用；3）随着时间推进，径向传热的主导机理依次为液态钠单相对流、钠蒸汽在组件盒内壁冷凝、体热源沸腾池散热。
