ECC condensation research in T-junction

• ECC condensation research based on China PWR- CPR1000.
• The correlation of condensation based on XJTU-ECC test was proposed.
• Wide range of RT number from 0 to 3.5 were analyzed within condensation.
• A new analysis method was proposed by using the mass fraction and RT number.
• The test report a conservative results on ECC component than RELAP5 calculation.
