Abstract
Thermal stratification in a pipe, which can lead to temperature fluctuations, has attracted much attention from researchers who study nuclear power plants. In particular, temperature fluctuation in the pressurizer surge line has been assessed as being a significant technical and safety issue due to its high rate of occurrence. The present work investigated thermal stratification of the tilted arrangement. Both the outer and the inner temperature distribution were extracted and analyzed. As the surge line inlet velocity increased, the regions where thermal stratification occurred gradually approached the hot leg. In addition, thermal stratification for the tilted arrangement was compared with that for the horizontal arrangement. The temperature difference along the surge line and the temperature patterns for the different arrangements were compared and analyzed.
