The agreement between these assessments and the phase equilibrium data available in the literature is generally good. In this work, the modified quasi-chemical model in the quadruplet approximation was used to develop new thermodynamic modelling assessments of the binary solutions, which are highly relevant in assessing the corrosion process in molten salt reactors. This work focused on the thermodynamic assessment of the CrF2−CrF3 system and the binary systems of chromium trifluoride CrF3 with alkali fluorides (LiF, NaF, KF) using the CALPHAD (computer coupling of phase diagrams and thermochemistry) method. Understanding the corrosion mechanisms and the effect of corrosion products on the basic properties of the salt (e.g., melting point, heat capacity) is fundamental for the safety assessment and durability of molten salt reactor technology. The activities of LiF, ThF4 and UF4 over the molten F1+3zLi1-zTh xUy (z = x + y, 1 ≤ x ≤ 0, 0 ≤ y ≤ 1) salts mixture have been computed using FTsalt-FACT salt phase diagrams database. The dynamic and kinematic viscosities, density and thermodynamic function as a function of temperature of molten fuel carrier salts F1.675Li0.775Th 0.1995U0.0255 mixture have been determined. The solidus, liquidus temperature and enthalpy of fusion values were determined for molten F1.675Li0.775Th 0. mixture to be 825 ± 3 K, 838 ± 4 K and (15.9 ± 4) kJ mol⁻¹, respectively. The thermo-physical and thermodynamic properties of this fuel salts mixture were measured using thermal analysis, Archimedes and Rheometric techniques.
Based on this pseudo-binary phase diagram and reactor criticality data, the composition of fuel carrier salts has been calculated as: F1.675Li0.775Th 0.1995U0.0255. LiF–ThF4 system has been established to be the most appropriate solvent for the fissile isotope ²³³U. The comprehensive information on LiF-ThF4-UF4 system is necessary for the development of new design molten salt reactors. 01204593254įor order Email : Quote and information order : No. We have special customer care for technical help.

A sturdy metal enclosing the heating block and controls is powder coated with textured siemens grey finish.Ībout LABORATORYDEAL – India’s Ultimate Online Shopping Site LABORATORYDEAL’s vision is to create India’s most reliable and frictionless commerce ecosystem that creates life-changing experiences for buyers and sellers. A second toggle switch on the right side connects the lamp and power input to the apparatus. Both the heaters are kept 'ON' in the 'LOW' as well as 'HIGH' position of the toggle switch, thus ensuring uniform heating from both sides of the block. A built in a rotary rheostat gives accurate adjustment of the rate of increase of temperature as melting point is approached. The built in lamp provides uniform and shadow less illumination of sample tube which are viewed through the magnifying lens against either a dark or bright ground selected by rotating a knob to the rear of the apparatus. The block is heated by two elements clamped to the sides. It consists of a aluminum block which accepts three capillary tubes & a mercury thermometer. Melting Point Measuring Instrument is very useful in the determination of the melting point of any substance in small quantity up to 300 C.
