- •
Multi-holes steam ejection induced flow and thermal effects for ADS 1–3 are evaluated.
- •
Stratification criteria are combined to predict and assess the thermal stratification.
- •
The improved ADS sparger arrangement is recommended to enhance the mixing effects.
- •
Multi-holes lumped “steam condensation column” is modeled to estimate the HTC.
