Abstract:

Abstract:Basic information of the circulating water system of a nuclear power unit was introduced. Based on analysis, it was pointed out that there is not pressure water injecton design in this system, and due to influence of tide levelthe unit startup may be delayed. The pipeline of circulating water and related equipments were analyzed, and a priliminary thermodynamic estimation was carried out. Based on these,the pressure water injection of the circulating water pipeline was proposed, and a method of small flow circulation during downtime was given.
