METHOD FOR EVALUATING HEAT RELEASE IN FUEL ELEMENT WHEN REFINING IT IN LOOP CHANNEL Russian patent published in 2004 - IPC

FIELD: nuclear power engineering; development of power generating channels of thermionic converter reactors. SUBSTANCE: proposed method used for developing fuel elements, including high-temperature thermionic ones, and experimentally refining them in nuclear reactors includes pressure measurement of gaseous fission products P in fuel element ventilation system at time moment t of interest, ventilated fuel element being used for the purpose; temperature measurement of fuel element cladding T_e; measurement of amount of fuel material m escaping from fuel element; calculation of maximal temperature in fuel core T₀ and evaluation of heat release q_v in fuel element using equations given in description of invention. EFFECT: enhanced precision of evaluating heat release in fuel element during its experimental refining in nuclear reactor. 1 cl, 4 dwg
