FIELD: electronic engineering; loop tests of reactor thermionic power-generating channels.
SUBSTANCE: proposed method includes measurement of volumetric heat emission density in fuel, recording of fuel re-condensation completion inside element cores, measurement or estimation of emitter temperature at midpoint of element length and temperature on axis of emitter shell end part at switching jumper end, measurement of re-condensed fuel thickness at midpoint of emitter length and at element end opposite point of measurement or estimation of temperatures; heat conductivity of oxide fuel is found from equation given in invention specification.
EFFECT: enhanced accuracy.
