In this paper, the thermal hydraulic design characteristics of the power conversion system for SMART 330 MWt plant which the once-through helically-coiled steam generators have been installed was analyzed. The feedwater temp., total feedwater flow rate, steam pressure, total steam flow rate and steam temp. was analyzed vs. steam generator power on conditions of a constant feedwater temp. and steam pressure, and was compared with the commercial nuclear power plants. After the present analysis, it was evaluated that at the range of low power(about below 20%) the steam temp. is nearly same as the core outlet temp., and at the range of meddle power(about between 20 ~ 80%) it show gradually a upward trend, and at the range of high power(about between 80 ~ 100%) it show gradually a downward trend. These phenomena result from the once-through steam generator's model which consists of the 3 different type of regions, i.e., subcooled, boiling, and superheated region.
