Abstract

The thermal hydraulic system analysis code APROS was validated by calculating PATEL NCg, PKL and ROSA experiments. The code capability to simulate conditions where non-condensable gas reduces heat transfer was enhanced. A second order space discretization method was implemented in APROS to better track sharp concentration fronts, like a slug of water with low boron concentration. The 3D porous media code PORFLO was improved so that large problems can be calculated. The wall condensation model implemented in the Fluent CFD code was tested by simulating the initial phase of the ISP-47 in the MISTRA test facility.
