abstract = "A heat exchanger concept is developed that extracts energy from liquid lithium reactor coolant to evaporate potassium used in a Rankine power cycle. The heat exchanger is based on flow channels with hydraulic diameters of order 100 microns, which evokes some physical flow characteristics not common to heat exchangers with conventional dimensions. Liquid metal superheat prior to incipience of boiling is explored and the potential for bulk liquid flow temperatures in excess of saturation is explained. Design methods to stabilize evaporator flow and to completely avoid liquid entrainment in the evaporator by limiting vapor velocity and liquid film Reynolds number are also developed.",
