Effects of diameters and fluid properties on flow characteristics in vertical pipes under flooding at the top end were evaluated, and it was judged that correlations for counter-current flow limitation (CCFL), wall friction factor fw and liquid film thickness δ might be applied to the pressurizer surge line with the diameter of about 300 mm.
