A comparison of the thermal hydraulic behavior of the Advanced Passive 600 MW(e) (AP600) and the Rig of Safety Assessment (ROSA) Large-Scale Test Facility (LSTF), under similar initial and boundary conditions, was developed through computer simulations of selected accident scenarios for the Nuclear Regulatory Commission. The purpose of the comparison was to develop criteria to evaluate the capability of a scaled integral facility to perform an AP600 safety assessment. It was concluded that ROSA LSTF, with a minimum of required modifications, is capable of reproducing most of the phenomena and behavior expected of AP600; distortions become important for slow transients and cases in which the nonsymmetric behavior of AP600 is relevant.
