Abstract

1. СПОСОБ УТИЛИЗАЦИИ МЕТАЛЛИЧЕСКИХ ОТХОДОВ, ЗАГРЯЗНЕННЫХ РАДИОНУКЛИДАМИ, включающий разделку отходов, контроль радиоактивной загрязненности с расчетом допустимого уровня, плвление в индукционной печи на воздухе с добавлением рафинирующих флюсов, наведение и удаление шлака, разливку металли в изложницы и контроль слитков металла, отличающийся тем, что после стадии контроля радиоактивной загрязненности при превышении расчетного допустимого уровня осуществляют дезактивацию металлических отходов, а плавление отходов проводят с многократным дополнительным наведением и удалением шлака, при этом количество операций наведения и удаления шлака определяют по формуле:n = 1(C) /1(T),где n - количество операций наведения и удаления шлака;C - необходимая кратность удаления шлака;T - кратность разбавления шлака за один цикл.2. Способ по п.1, отличающийся тем, что дезактивацию металлических отходов осуществляют методом, обеспечивающим глубокую очистку от радионуклидов с высоким сродством к металлу.3. Способ по п. 1, отличающийся тем, что скаченный во время дополнительного наведения и удаления шлак используют в качестве рафинирующего флюса при переплавке последующей партии металлических отходов.1. METHOD FOR DISPOSAL OF METAL WASTE CONTAMINATED WITH RADIONUCLIDES, including cutting waste, control of radioactive contamination with the calculation of the permissible level, melting in an induction furnace in air with the addition of refining fluxes, guiding and removing slag, pouring metal into molds and controlling ingots that after the stage of radioactive contamination control, when the calculated permissible level is exceeded, the metal waste is decontaminated, and the waste melting is carried out with repeated additional guidance and slag removal, while the number of operations for the introduction and removal of slag is determined by the formula: n = 1 (C) / 1 (T ), where n is the number of operations for directing and removing slag; C is the required rate of slag removal; T is the rate of dilution of slag in one cycle. 2. The method according to claim 1, characterized in that the decontamination of metal waste is carried out by a method that provides deep cleaning from radionuclides with a high affinity for metal. The method according to claim 1, characterized in that the slag downloaded during the additional guidance and removal is used as a refining flux in the remelting of the subsequent batch of metal waste.
