Abstract: AbstractThe VATT-02 experiment, performed at Vattenfall, Sweden, with a 1/5 th -scale model of a 3-loop PWR pressure vessel, has been simulated with the Computational Fluid Dynamics (CFD) code CFX-5 at PSI, Switzerland. The simulations were initially part of the FLOMIX-R EU 5 th Framework Programme, aimed at providing validation data prior to CFD codes being used to model full-size nuclear vessels. These studies were extended at PSI to examine mesh effects. Steady-state velocities and transient boron concentr…
