Résumé

TOSQAN is an experimental program undertaken by the Institut de Radioprotection et de Sûreté Nucléaire (IRSN) in order to perform thermal hydraulic containment studies. The TOSQAN facility is a large enclosure devoted to simulate typical accidental thermal hydraulic flow conditions in Nuclear Pressurized Water Reactor containment, especially suitable for making detailed measurements by non-intrusive optical diagnostics. In the first part of this paper, we describe advanced optical diagnostic used to characterize two-phase flow during the course of spray test, and in the second part, we present some results about water spray interaction with air / steam mixture.
