Abstract

[Molten salt reactors (MSR) are Generation-IV fission reactors. MSR is a class of nuclear fission reactors in which the coolant is a mixture of molten salts. They are very compact design of nuclear reactors. Many agencies working on this conclude that MSR can deliver a safe, economical, sustainable energy, without generation of CO2 gas. As MSRs operate at very high temperatures compared to water cooled reactors, they have high thermodynamic efficiency. The molten salts are more efficient than compressed helium as it can remove more heat from core, hence making the system more compact. However, many constraints have been identified which could create setbacks in MSR. Many of these have been addressed to a large extent by various research works that were carried out throughout the world. This paper reviews the evolution of molten salts as coolant and since the Indian nuclear program has identified FLiNaK as one of the candidate coolants for the Indian MSR, a review on the degradation of structural materials in FLiNaK medium is also presented and discussed.]
