Keywords:Pressurizer surge line , Vertical pipe, Countercurrent flow limitation, Kutateladze parameter, Fluid properties

Effects of fluid properties for countercurrent flow limitation (CCFL) at the upper end of the vertical pipe in a pressurizer surge line were evaluated, and the CCFL constant of C_K = 1.4±0.2 was obtained by using a Wallis correlation with Kutateladze parameters.
