Resumo
Currently, there are six Generation
IV nuclear reactor designs in development.
Four are fast neutron reactors, and all designs
operate at higher temperatures that permit
hydrogen production. Thus, the interest in
fluoride salts has grown due to their hightemperature
application in fission and fusion
reactor designs. The aircraft propulsion project
was the initial plan, which used molten salt as
a coolant and was started by Bettis and Briant
in the 1940s. The molten salt reactor has been
designed to operate at temperatures of 700 to
800°C with fissile material dissolved in a molten
fluoride salt composition. Molten fluoride
salts are stable at high temperatures, show
good thermodynamic properties, and can also
dissolve actinides and fission products easily.
It creates a candidate for a thorium reactor
with more than 45% efficiency. The purpose
of this work was to investigate the physical
characteristics of two systems of fluoride salt
combinations, namely LiF-BeF2 (FliBe) and
LiF-NaF-KF (FliNaK), including melting
temperature, density, and heat capacity. The
aim is to characterize the advantages of the
various designs proposed for Generation IV
by reviewing properties evidenced by safety
improvements and limitations.
