Electrical Penetration Assembly for Fast Critical Assembly
-
摘要: 介绍了用于快中子临界装置堆厅且不截断电缆的电气贯穿件,该贯穿件结构简单,便于电缆更换。贯穿件气密性试验和堆厅整体密封包容性试验结果表明,电气贯穿件的气密性优于设计指标,且使得堆厅整体密封包容性满足快中子临界装置正常运行和事故情况下的使用需求。Abstract: A electrical penetration assembly which does not require to cut cables and can be used in the hall for the fast critical assembly is introduced in this paper. The structure of the electrical penetration assembly is simple and facilitates the cable replacement. The results from the leakage test on the electrical penetration assembly and the hall indicate that the leakage ratio is less than the design ratio, and the overall seal performance of the hall satisfies the requirement on the normal operation and accident conditions for the fast critical assembly.
