摘要
为分析环境温度和安全壳外表面发射率对小型压水堆非能动安全壳空气冷却系统换热能力的影响,本文采用Ansys Fluent软件建立了非能动安全壳空气冷却系统的计算模型,分析了非能动安全壳空气冷却系统在事故后的稳态换热能力。结果表明:非能动安全壳空气冷却系统换热能力随环境温度的升高而降低,环境温度对非能动安全壳空气冷却系统换热能力影响较明显;非能动安全壳空气冷却系统换热能力随安全壳外表面发射率的升高而升高,安全壳外表面发射率对非能动安全壳空气冷却系统换热能力影响较小。以上结果可以为非能动安全壳空气冷却系统在不同环境温度及安全壳外表面发射率发生变化后的换热能力提供基础数据,也可以为今后小型压水堆在环境温度较低的高纬度地区建设提供参考。
This paper aims to analyze the effect of ambient temperature and emissivity of the outer wall of the containment shell on the heat transfer capacity of the passive containment air cooling system for small modular pressurized water reactors.Thus,Ansys Fluent was used to build a simulation model for the passive containment air cooling system to analyze the steady-state heat transfer capacity of the passive containment air cooling system after accidents.The results showed that the heat transfer capacity of the passive containment air cooling system decreases with increasing ambient temperature.The effect of ambient temperature on the heat transfer capacity of the passive containment air cooling system is obvious.The heat transfer capacity of the passive containment air cooling system increases with increasing emissivity of the outer wall of the containment shell.The emissivity of the outer wall of the containment shell has a minimal impact on the heat transfer capacity of the passive containment air cooling system.The results can provide some basic data for the heat transfer capacity of the passive containment air cooling system under different ambient temperatures and emissivities of the outer wall of the containment shell.Moreover,these results can provide some references for the establishment of small modular pressurized water reactors in high-latitude areas with low ambient temperatures in the future.
