Abstract : An integrated high power modular thermionic power system is described which comprises a heat source including a generally cylindrically shaped chemical reaction chamber enclosing a first chemical reactant, such as lithium, for exothermal reaction with a second chemical reactant, such as sulfur hexafluoride, controllably supplied from a separate source thereof to the reaction chamber; a plurality of ring shaped thermionic modules disposed around the reaction chamber with the thermionic emitter elements thereof in thermal contact with the reaction chamber and collector elements concentrically disposed around the emitters; a cylindrical heat sink disposed around the thermionic modules in thermal contact with the collector elements for absorbing heat therefrom; a plurality of heat radiating fins on the outer surface of the heat sink; and one or more heat pipes having the respective evaporator ends in thermal contact with the heated sink and the condenser ends disposed remote of the heat sink for conducting heat there-from.
