Formulation of a two-fluid model for mixing in LWR bundles

  • 1. Dept. of Nuclear Engineering, Massachusetts Institute of Technology, Cambridge, MA

Description

The space and time averaged two-fluid flow equations are shown to lead to distributive and turbulence terms, which can be lumped into one term to explain two-phase lateral mixing in rod bundles. A model is developed for this mixing and applied into the THERMIT two-fluid code. The model predictions were tested against small rod bundle tests for pressure and quality conditions representative of BWR and PWR conditions. The model successfully predicts the observed low quality in the corner subchannel for BWR conditions. It also predicts the essentially uniform quality distribution for PWR conditions
