| Abstract Scope |
Molten salt is one of promising materials present in nuclear energy applications as liquid fuel or coolant of Generation IV reactors and electrochemical processing of spent nuclear fuel. Since density is one of fundamental physical properties, the accurate measurement of density is in need for various studies about molten salt. In this study, calibration graphs showing relationship between volume and height of a fluoride salt sample were made and used to measure density at high temperature. The volume of samples at each temperature was calculated based on data from a previous study, and the height of samples were measured in this study. Samples with a LiF-NaF-KF (46.5-11.5-42.0 mol%) composition were used to draw the calibration graphs, and this methodology was verified with a LiF-ThF4 (80.0-20.0 mol%) salt mixture by comparing this study’s results with ideal mixture prediction and data from a previous study. The deviation was about 2% or lower. |
