摘要

In the framework of the new generation of nuclear fission reactors, one of the promising systems is the Molten Salt Fast Reactor (MSFR). It is a thorium-fuelled fast spectrum reactor in which the fissile and fertile materials are dissolved into a molten salt mixture. The salt considered as primary candidate in this concept is the binary system LiF-ThF_4 with the addition of ~(235)U or ~(239)Pu in the form of fluorides serving as start-up fissile materials. For the design of the reactor and in order to determine its safety limits, it is extremely important to have an accurate description of the physico-chemical properties of the fuel salt (such as the melting point, the boiling point and the vapour pressure). This goal can be achieved by developing a thermodynamic database, which is based on the available experimental data and which allows prediction of all the other important properties.
