Abstract
Способ комплексной переработки твердых радиоактивных отходов методом плавления в электрической печи постоянного тока, отличающийся тем, что переработка ТРО происходит путем их расплавления «джоулевым» теплом, выделяемым при протекании постоянного тока в расплаве между опускным электродом и донной фазой печи, под действием высокой температуры, сил гравитации, действия электрического поля и режимов переработки осуществляется перераспределение и фиксация различных радионуклидов в конечных компонентах переработки по их физико-химическим свойствам; основным компонентом конечной продукции переработки является монолитный стеклообразный композит с высокой механической прочностью и химической стойкостью, с гарантированной фиксацией радионуклидов на весь период хранения до необходимого уровня их распада. A method of complex processing of solid radioactive waste by melting in an electric DC furnace, characterized in that the SRW is processed by melting it with "joule" heat released during direct current flow in the melt between the dip electrode and the bottom phase of the furnace, under the influence of high temperature, forces gravity, the effects of the electric field and processing modes, redistribution and fixation of various radionuclides in the final components of the processing by their physicochemical Kim properties; the main component of the final processing product is a monolithic glassy composite with high mechanical strength and chemical resistance, with guaranteed fixation of radionuclides for the entire storage period to the required level of their decay.
