An Analysis of Fluids for the Transport of Heat with HTGR

Steam and the molten salt FLiNaK perform better than helium, carbon dioxide and DOWTHERM A. The molten salt does not go through a phase change and therefore pressure has no influence on the heat transfer capabilities. At pressures near 20 MPa, steam is the most effective, if the boiler at the well pads has a minimum approach temperature
