在海上浮式核电平台设计中，存在主机舱排水口排出的温排水影响核反应堆冷却水循环系统进水口海水温度的问题。本文采用基于有限体积法的三维数值方法对海上浮式核电平台船体外域温排水的扩散特性进行计算，研究环境水流速度、排水角度和排水口形状对温排水扩散规律的影响，并找到浮式核电平台主机舱排水口的最佳设计参数。结果表明，环境水流速度、排水角度和排水口形状不同，船体底部温度场的变化较大。计算结果为海上浮式核电平台船主机舱排水口的设计提供重要的指导意义。
In the design of a floating nuclear power platform, there is a problem that the thermal discharge of the main engine room affects the seawater temperature of the inlet of the cooling water circulation system. In this paper, the finite volume method and the Reynolds average method were used to calculate the diffusion law of thermal discharge of floating nuclear power platform. The influences of environmental water flow velocity, drainage angle and outlet shape on the diffusion law of thermal discharge were studied, and the optimal design parameters of the outlet in the main engine room of the floating nuclear power platform are found. The results show that the temperature field at the bottom of the hull varies greatly with the different water velocity, drainage angle and outlet shape. The conclusion of this study will provide important guidance for the design of floating nuclear power platform.
