NUCLEAR REACTOR CONTAINMENT FLOWS-MODELLING OF STABLY STRATIFIED LAYER EROSION BY A TURBULENT JET Academic Article uri icon

abstract

  • ABSTRACT A number of international benchmarks were devoted to revealing the capability of CFD codes to predict the temporal evolution of the concentration and velocity fields of the nuclear reactor containment atmosphere in the course of severe accidents. In the most recent OECD/NEA international benchmark exercise on containment flows, a stably-stratified helium-air layer was eroded by a free turbulent jet coming from below. Velocity and helium concentration fields were measured in the course of the experiment. The results of the …
