Adequacy of the heat-mass transfer analogy to simulate containment atmospheric cooling in the new generation of advanced nuclear reactors: experimental confirmation

摘要

Driving forces of passive cooling systems of ad- vanced reactor containments are substantially weaker than those brought in by active systems of operating power plants. This fact along with the new geometries being used suggest the need either to develop new reliable sim- ulation techniques or to adapt and validate traditional approaches. Suitability of the heat-mass transfer anal- ogy for this purpose is investigated based on previous author's experience. Major analogy drawbacks are iden- tified and overcome by supplementing it with analyti- cally derived factors.
