POOL: A Two-Dimensional Three-Component Coupled Hydrodynamic Thermodynamic Computer Model for Boiling Pools of Fuel and Steel.

摘要

The model described was developed as a substitute for VENUS II and has been coupled to FX2to yield a completely interactive thermohydraulic-neutronic computer program which describes the interactions in a boiling cylindrical pool of fuel and steel. The model treats the Eulerian Hydrodynamics and Thermodynamics of the interactions in the pool and feeds back to FX2for Neutronic coupling. Specifically treated in this model are:heat transfer between fuel and steel both inside the pool and at the boundaries;boiling of steel and fuel,melting of steel at the pool contact boundaries and condensation of vapor at the top boundaries;pressurization inside the pool and on top;hydrodynamic (Navier Stokes and continuity) internal motion;and thermodynamic heat diffusion/convection.
