The objectives of this study are to predict CANDU moderator temperatures by using the CUPID code and to validate the CUPID against STERN 2D experimental data. In this study, both single and two phase flows in the Calandria vessel were calculated by using the CUPID code. KAERI has been developing the CUPID Code. It adopts three-dimensional, transient, two-phase and three-field model, and includes various physical models and correlations of the interfacial mass, momentum and energy transfer for the closure relations of the two-fluid model. The CUPID code validated using the single-phase flow experimental data that were performed in the STERN Lab.
