Study on computer analysis method of a steam generator heated by liquid metal sodium

摘要

This paper describes a multi-shell analysis method to predict the thermal-hydraulics in a steam generator of the liquid metal fast reactor. Accuracy of the calculations were examined by the horizontal temperature distribution data under the steady state and transient conditions that had been measured in the 50MW steam generator test facility in O-arai engineering center of JNC. As the results, the accuracy of the calculation concerning to the outlet steam temperature is evaluated within ±15K for almost all of the range of flow condition.
