某核电厂循环水系统虹吸井布置优化分析

Analysis and Optimization of Circulation Water Siphon Well Position in a Nuclear Power Plant

在辽宁某核电厂循环水虹吸井的设计中,其选址有设于渤海岸边和设于厂区两个方案。在优化设计中,通过对循环水系统进行水力计算,分析了不同方案对循环水泵扬程的影响,以及对循环水系统的安全性和核电厂布置、机组运行的经济性的影响。经综合分析后,推荐采用将循环水虹吸井布置在厂区的方案。

In the design of circulating water siphon well in a nuclear power plant in Liaoning Prov- ince, there were two schemes that its position was located at the coast of Bohai Sea or in the plant. The influence of the two schemes on circulating water pump head, safety of circulating water system, layout of nuclear power plant and economy of unit operation was analyzed by hydraulic calculation of circulating water system in the optimization design. After comprehensive analysis, the circulating water siphon well was recommended to be located in the plant.
