Intermediate Heat Exchanger and Steam Generator Designs for the HYLIFE-II Fusion Power Plant Using Molten Salts

The HYLIFE-II fusion power plant employs the molten salt, Flibe, for the liquid jets which form the self-healing “first wall” of the reactor. The molten salt, sodium fluoroborate then transports the heat from the IHX's to the steam generators. The design and optimization of the IHX's and the steam generators for use with molten salts has been done as part of the HYLIFE-II conceptual design study. The results of this study are described, and reference designs of these large heat exchangers are selected to minimize the cost of electricity while satisfying other important constraints.
