Abstract

The present work aims at verifying a sub-channel analysis program based on a drift-flux model by applying it to traditional VVER-1000 hot fuel assembly in steady-state and operational transients. Liquid enthalpy, mass velocity and liquid temperature calculated then compared with the final safety analysis report data. According to the results the code outputs are in good agreement with experimental data.
