The design of heat exchangers for molten salt reactors involves so many parameters and their interrelationships are so complex that it is difficult to envision the effects of the various trade-offs that can be made in attempts to optimize the system. This report presents a procedure for carrying out such analyses together with the results of a parametric study showing the effects of tube diameter, fuel pressure drop, inert salt pressure drop, and the temperature difference between the fuel and the inert salt with either NaBF4 or Flinak as the fluid-in-the intermediate heat trans-port system. An unusual design for a 2200 Mw(t), 100 Mw(e) power plant was used as the reference design for the detailed calculations of the parametric study presented in this report.
