Abstract
1. Способ очистки облученного ядерного топлива в хлоридных расплавах, содержащих продукты растворения оксидного топлива посредством хлорирования, путем поэтапного извлечения электроположительных продуктов деления, отличающийся тем, что извлечение электроположительных продуктов деления осуществляют путем погружения в расплав пластины металлического молибдена и ее выдержки в контакте с расплавом в течение 2-5 ч, с последующей очисткой расплава от растворившегося молибдена.2. Способ по п.1, отличающийся тем, что растворившийся в расплаве молибден удаляют путем продувки расплава газообразным хлором.1. A method of purifying irradiated nuclear fuel in chloride melts containing the products of dissolution of oxide fuel by chlorination, by stage-by-stage extraction of electropositive fission products, characterized in that the extraction of electropositive fission products is carried out by immersing a plate of metal molybdenum in the melt and keeping it in contact with the melt in for 2-5 hours, followed by purification of the melt from dissolved molybdenum. 2. The method according to claim 1, characterized in that the molybdenum dissolved in the melt is removed by blowing the melt with gaseous chlorine.
