In this study, we experimentally investigate of a two-phase natural circulation loop that functions as apassive containment cooling system (PCCS). The experimental apparatus comprises two loops: a hotloop, for simulating containment under severe accidents, and a natural circulation loop, for simulatingthe PCCS. The experiment is conducted by controlling the pressure and inlet temperature of the hot loopin the range of 0.59e0.69 MPa (abs) and 119.6e158.8 C, respectively. The heat balance of the hot loop isestablished and compared with a natural circulation loop to assess the thermal reliability of theexperimental apparatus, and an additional system is installed to measure the vapor mass flow rate.
Furthermore, the thermalehydraulic characteristics are considered in terms of a temperature, mass flowrate, heat transfer coefficient (HTC), etc. The flow rate of the natural circulation loop is induced primarilyby flashing, and a distortion is observed in the local HTC because of the fully develop as well as subcooledboiling. As a result, we present the amount of heat capacity that the PCCS can passively remove accordingto the experimental conditions and compared the heat transfer performance using Chen's and DittusBoelter correlation.
