摘要：

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. © 2023 Editorial Board of Journal of Harbin Engineering.
