Keywords:Pressurizer surge line, Hot leg, Countercurrent flow limitation, One-dimensional computation, Interfacial friction correlation

Effects of an interfacial friction correlation with a function of the gas Reynolds number used for one-dimensional computation of countercurrent flow limitation (CCFL) in nearly horizontal pipes on computed results were evaluated, and an adjustment function with the dimensionless diameter was obtained to fit computed results with CCFL data in the range of D = 0.03-0.65 m.
