The JUPITER code developed by JAEA is examined to apply for the single-phase and two-phase flow simulation of LWR fuel assembly with the vane. The simulation results of single-phase flow were compared with the data of previous experimental study. The effect of the vane on the flow field and bubble behavior are discussed and some issues to be considered are extracted.
