In order to study the heat and mass transfers between the spray droplets and the atmosphere for thermal-hydraulics conditions representative of a severe accident in a Pressure Water Reactor, the French Institute for Radioprotection and Nuclear Safety (IRSN) developed the TOSQAN facility. This paper is devoted to present the development and the qualification of the global rainbow refractometry in order to measure falling droplet temperature.
