A multi-shell analysis method has been applied to predict the thermal-hydraulics in a steam generator of the liquid metal fast reactor by using a MSG code(Multi-dimensional analysis code for Steam Generators). Accuracy of the calculations were examined by the horizontal temperature date under the steady state conditions which had been measured in the 50MW steam generator test facility in O-arai engineering center of PNC. As the results, the accuracy of the calculation concerning to the outlet steam temperature is evaluated within ±15K for all of the range of flow condition. And also, the accuracy of sodium temperature is evaluated within ±20K for almost all of the temperature data in the helical coil tube region. inside of the tubes. The main heat exchange is performed in a helical coil tube region which corresponds to the region between inner and middle shell. And the downcommer region corresponds to the region between middle and outer shell where the single phase water flows downward in tubes for the preheating. In the inner shell region, sodium accumulated to keep the sodium level in the steam generator. All of the these three regions divided by three-shells are connected at lower plenum. In order to predict the thermal hydraulics in such a complex configuration of steam generator, the multi-shell analysis method is developed to improve the prediction accuracy of temperature distribution, especially, concerning to the horizontal direction in the helical coil region.
