Molten salt reactors

Molten salt reactors (MSRs) is an area of growing interest in sectors both private and public. Many advocates of MSRs talk of their potential to deliver safer nuclear power, bringing to the world energy sustainability without the generation of CO2 emissions and at a market-competitive price. Molten salt reactors are characterized by the use of fluoride salts as coolant, in particular7 lithium-beryllium fluoride (FLiBe) salts.

The salt is not dissolved in water, the salt itself in molten form is the coolant. FLiBe salts have excellent heat transfer characteristics. The molten-salt carries a similar amount of heat per unit volume of water, remain liquid up to 1400°C giving incredible safety margins and unlike water does not need pressurisation at high temperatures.
