Abstract: In the oncethrough cooling water system of power plant, the siphon well plays important role. The rationality of the siphon well design scheme influences on the safety of the system operation greatly. Under the extreme condition of the hydraulic transient process, combining with the practical project example of the YH Power Plant, the influence of the siphon well arrangement scheme on the safety of system operation was analyzed. The improvement measures of the arrangement scheme were proposed, and the general design principle of siphon well arrangement scheme was summarized.
