摘要：

The thermal properties of 2LiF-BeF2 and LiF-BeF2-UF4 systems currently under active development for use in molten salt reactor designs, in various countries are studied. In order to establish liquidus and solidus temperatures of these systems, the Differential Scanning Calorimetry (DSC) method at a constant heating (cooling) rate was used. A distinction between results obtained in heating and cooling mode is identified on the basis of the much lower solidus peaks observed on cooling curves than on heating ones. This can be explained in terms of peculiarities of LiF-BeF2 peritectic compositions. The rate of cooling is much higher than the peritectic reaction rate. (C) 2021 Elsevier B.V. All rights reserved.
