Thermo-hydraulic characteristics of the helically coiled tube and the condensate heat exchanger for SMART

► SMART plant and TASS/SMR code have been developed by KAERI. ► Two-phase heat transfer test at helical tube is performed for SMART accident conditions. ► Condensate heat transfer test at downward straight tube is performed for SMART PRHRS design. ► Capability of MARS and TASS/SMR codes is validated using experimental results.
