Research on the Scheme to Avoid Water Hammer Damage of Pressurized Water Reactor SG Heat Transfer Tubes
Year: 2026
Type: conference-paper
Abstract: Due to the design characteristics of the steam generator (SG) of the HUALONG-1 unit and considering the full range of accident analysis, during the normal refueling overhaul of the unit, there is a risk of water hammer in the SG heat transfer tube due to the accidental start-up of the safety injection pump before opening the pressure vessel head, which leads to the risk of damage to the SG heat transfer tube. This paper analyzes the mechanism of water hammer in the SG heat transfer tube, proposes a solution to avoid water hammer hazards, and considers a feasible solution to save the critical path time of the overhaul to improve the safety and economy of the unit operation.
