An experiment was performed using a horizontal condenser tube for the PCCS horizontal heat exchanger to confirm the performance and to estimate the thermal-hydraulic behavior in the tube thermally and visually. The PCCS, driven by the pressure difference between the drywell and wetwell, is a safety equipment to prevent the containment break for more than 1 day due to overpressurization at the containment spray failure situation. An annular flow, a wavy flow, a supercritical flow, a stratified flow and the liquid slug propagation are observed in the tube at the nominal condition. The flow regime transition, induced by the condensation, roughly agrees to the existing models. The observation also agrees with the condensate distribution in the tube circumference direction, which is suggested by the local thermal characteristics.
