“…Such properties require systems for which the constituent elements have small mass so that isotope variation can give relatively large changes to the nuclear masses, e.g., ultra-small-mass rocksalt compounds LiH and LiF, both of which have a significant amount of measured data for both dispersions and κ. Natural isotopic variance of Li is 7.6% 6 Li and 92.4% 7 Li, while H and F LiF is used in radiation detection [13] and ultraviolet optics [14], and LiF salts are used as solvents in nuclear reactors [15].…”

Engineered isotope variation is a pathway toward modulating lattice thermal conductivity (κ) of a material through changes in phonon-isotope scattering. The effects of isotope variation on intrinsic thermal resistance is little explored, as varying isotopes have relatively small differences in mass and thus do not affect bulk phonon dispersions. However, for light elements isotope mass variation can be relatively large (e.g., hydrogen and deuterium). Using a first principles Peierls-Boltzmann transport equation approach the effects of isotope variance on lattice thermal transport in ultra-low-mass compound materials LiH and LiF are characterized. The isotope mass variance modifies the intrinsic thermal resistance via modulation of acoustic and optic phonon frequencies, while phonon-isotope scattering from mass disorder plays only a minor role. This leads to some unusual cases where κ values of isotopically pure systems ( 6 LiH, 7 Li 2 H and 6 LiF) are lower than the values from their counterparts with naturally occurring isotopes and phonon-isotope scattering. However, these κ differences are relatively small. The effects of temperature-driven lattice expansion on phonon dispersions and calculated κ are also discussed.This work provides insight into lattice thermal conductivity modulation with mass variation and the interplay of intrinsic phonon-phonon and phonon-isotope scattering in interesting light atom systems.

“…First one as further energy and heat producing breeding power utility, operating under 232 Th-233 U fuels, second one as transmuter burning plutonium and minor actinides (Np, Am, Cm). So, the MSR concept can address two relevant objectives; an elegant utilization of fuel materials for electricity generation (or heat, for so-called Hydrogen economy) with minimum long-live radiotoxic wastes as well as significant radiotoxicity decrease from light water reactor (LWR) wastes, initially destined for ultimate repository [2][3][4][5].…”

“…During its operation from 1965 to 1969, three different fissile materials were used; 235 UF 4 , 233 UF 4 and 239 PuF 3 . Carrier salt composed of 7 LiF, BeF 2 and ZrF 4 and LiF-BeF 2 mixture floated through secondary circuit of the reactor [3,5]. The next project labelled as Molten Salt Breeder Reactor (MSBR), powered as 232 Th-233 U breeding reactor [8], was in development from late 60s to 1976, when it was shut down.…”
