Brief Introduction to Chinese advanced reactors 2.1 CAP1400 ➢ ADS-4 entrainment and upper plenum entrainment experiments-ADETEL ➢ Original data of entrainment onset HL liquid level (downstream the branch) (Pa) HL liquid level (downstream the branch) (Pa) DP-3 (Pa) Entrained liquid mass (kg) Air flow rate (kg/h) The liquid levels kept falling and oscillated vigorously. Amplitude about 10% of full range. Amplitude of DP-3 kept falling. The magnitude and frequency of entrainment keep falling. Air flow rate oscillated between 361-371kg/h. Amplitude about ±2.5% of full range. Entrained liquid mass increased slightly by 7kg
