摘要：
In order to study the pressure suppression effect of suppression system of small PWR, a small containment pressure suppression characteristic test device is established. Constant flow mixed gas emission test and variable flow mixed gas emission test are carried out to study the influence of gas-water volume ratio and non-condensable gas on the pressure suppression effect. The experimental result results show that when the gas-water volume ratio is in the range of 2~4.55, the pressure suppression effect gradually increases with the increase of the gas-water volume ratio; The content of non-condensable gas in the mixed gas has a significant influence on the pressure suppression effect. The numerical simulation of the experiment is carried out, and the simulation results can reflect the phenomenon law of the pressure suppression test, but the pressure suppression condensation model still needs to be further optimized to improve the simulation accuracy. © 2023 Yuan Zi Neng Chuban She.
