Abstract

En 中文
• Post-LOCA thermal-hydraulic behavior of a submerged small-scale containment is experimentally studied. • Internal temperature distribution and transient temperature–pressure characteristics under various parameters are obtained. • Partial submersion (μ = 1/2) increases peak temperature and pressure by ∼10% over full submersion. submergence level μ should preferably not be lower than 1/2. • Film model with dry/wet wall partitioning outperforms Uchida and Gido/Koestel models.
