Abstract: The invention provides a method for the transportation of at least one material in a molten state from a first location to a second location, the method comprising the use of transfer means comprising a fluidic pump to effect the transportation of said at least one material. The preferred type of fluidic pump is the Reverse Flow Diverter (RFD) Pump. Preferably, the at least one material in a molten state comprises at least one molten inorganic salt or molten metal, preferably alkali metal halides such as potassium chloride or lithium chloride, or eutectic mixtures thereof. The materials are in a molten state, at a temperature which is usually in excess of 200° C. A preferred gas for use according to the method of the invention is dry argon. In a particularly preferred embodiment, the method of the present invention is applied to the transportation of molten salts in dry conditions in various applications in the nuclear industry.
