Scaling analysis based on scaling laws was performed first for a single-phase natural circulation loop. Two geometrical reduced models were built. Numerical simulations for them using a CFD code named FLUENT were carried out. The calculated heat removal capabilities of the two reduced models show good agreement with the predicted results by the RELAP5/Mod3.2. The reversely deduced heat removal capabilities of the loop prototype from the numerically calculated results agree well with the prediction by the RELAP5/Mod3.2 for full height scaling model.
