A flow model is formulated to analyze the single-and two-phase flow characteristics in the primary side of a vertical, inverted U-tube steam generator. Using the flow model, a pressure drop-mass flow rate curve is derived. It is shown that the curve has a negative slope and, thus, flow excursion ins
