THERMOEMISSION ELECTROGENERATING MODULE OF NUCLEAR REACTOR CORE WITH DIRECT ENERGY CONVERSION

摘要

FIELD: physics, nuclear physics. ^ SUBSTANCE: invention is related to the field of thermal energy conversion into electric energy and may be used as source of power supply in space nuclear power plant. Thermoemission electrogenerating module of nuclear reactor with direct conversion of energy comprises cylindrical body with end nozzles and lead-throughs, thermoemission electrogenerating elements with emitter and collector, annular fuel elements and central pipe. Coating that emits electrons is applied on emitter. Collector is made of two coaxially installed internal and external cylindrical electrodes. External cylindrical surface of internal electrode and internal cylindrical surface of external electrodes of collector are equipped with coating that absorbs electrons. Fuel element of every subsequent thermoemission electrogenerating element is installed with axial gaps between internal and external cylindrical electrodes of previous thermoemission electrogenerating element collector. ^ EFFECT: increase of nuclear power plant reliability and its service life. ^ 8 cl, 4 dwg
