滨海核电厂厂坪标高优化

Optimal Design of Floor Elevation for Coastal Nuclear Power Plant

确定滨海核电厂厂坪标高主要考虑的因素有厂址设计基准洪水位、循环水泵运行费用和场地土石方挖填平衡。在满足厂址设计基准洪水位要求的情况下,厂坪标高的确定与常规岛侧主厂房布置方案密切相关。对常规岛侧主厂房局部下沉、整体下沉等4种不同布置方案进行了技术经济性分析,得到了最优的厂坪标高。

The main factors to be considered in determining the floor elevation of coastal nuclear power plant include the site design datum flood level,the operation cost of circulating pumps and the balance of earth-rock.When the requirement of site design datum flood level is satisfied,determination of the floor elevation is closely related to the layout of the main power plant on the conventional island side.In this paper,through a case study of a coastal nuclear power plant under construction,a technical and economic comparison is carried out on the 4 different layout schemes of main power plant on the conventional island side and the optimal plant floor elevation is obtained.
