FIELD: manufacture of thermionic converter reactor. SUBSTANCE: assembly of thermionic electricity-generating elements connected in series by means of switching jumper has each element provided with fuel-emitter unit in the form of short cylinder whose side surface and one of end surfaces function as emitter, and collector made in the form of flat-base cylindrical shell, spacing system, collector insulation and cover common for all elements; switching jumper is flexible to regulate interelectrode gap. EFFECT: provision for direct thermal-to-electric energy conversion. 1 dwg
