The present study describes the full thermodynamic assessment of the LiF–NaF–BeF2–ThF4–UF4 system which is one of the key systems considered for a molten salt reactor fuel. The work is an extension of the previously assessed LiF–NaF–ThF4–UF4 system with addition of BeF2 which is ...
活度系数混合焓计算模型本文采用修正的似化学模型和非对称的插值方法对先进反应堆中使用的三元氟化盐LiF-NaFBeF2体系的活度系数和混合焓进行了计算,并与修正的McGlashan-Rastogi模型和Harris-Prausnitz模型的计算结果进行了比较.修正的似化学模型计算的BeF2活度系数与实验值的相对偏差绝对平均值为10.7%,好于另外两个模型...

The set of thermodynamic properties of high-temperature, weakly nonideal Flinabe (LiF-NaF-BeF2) gas is calculated and presented. High-temperature Flinabe gases (plasmas) appear in the inertial fusion energy chamber over a wide range of temperatures and pressures due to the absorption of X-...
The molten salt Flinabe (LiF-NaF-BeF) is proposed as a liquid wall material for future fusion reactors because of its many attractive aspects. High-temperature Flinabe gases (plasmas) appear in the inertial fusion energy chamber over a wide range of temperatures and pressures because of the ...
The thermodynamic properties of molten BeF2 were modeled.The Soft-Sphere Equation of State (SSEOS) was used for this.Parameters of SSEOS were determined by regression to data.SSEOS was then modified to work on LiF–BeF2, NaF–BeF2, and KF–BeF2....
