Claims (4)

1. Способ дезактивации твердых радиоактивных отходов, заключающийся в выщелачивании из них радия с помощью горячей воды, кислых или щелочных растворов, отличающийся тем, что твердые радиоактивные отходы, например, нефтешлам, предварительно подвергают отжигу при недостатке кислорода в атмосфере угарного газа и других продуктов неполного сгорания углерода, где в качестве источника угарного газа используют углеводород, например, парафин или другие нефтепродукты, при этом температуру отжига выдерживают в диапазоне 700-900°С от 1 до 3 ч, причем отожженный нефтешлам обрабатывают горячим паром, затем нефтешлам после выщелачивания повторно обрабатывают горячим паром с соляной кислотой при концентрации соляной кислоты от 5 до 10% по отношению к массе выщелачивающего раствора.1. The method of decontamination of solid radioactive waste, which consists in leaching radium from them using hot water, acidic or alkaline solutions, characterized in that the solid radioactive waste, for example, oil sludge, is preliminarily annealed with a lack of oxygen in the atmosphere of carbon monoxide and other products of incomplete carbon combustion, where a carbon monoxide is used as a carbon monoxide source, for example, paraffin or other petroleum products, while the annealing temperature is maintained in the range of 700-900 ° C for 1 to 3 hours, and the burned oil sludge is treated with hot steam, then the oil sludge after leaching is re-treated with hot steam with hydrochloric acid at a concentration of hydrochloric acid from 5 to 10% with respect to the weight of the leach solution. 2. Способ по п.1, отличающийся тем, что в смесь, подвергаемую восстановительному отжигу, добавляют хлорид кальция в соотношении 1:10-1:20 по отношению к массе отжигаемого нефтешлама.2. The method according to claim 1, characterized in that in the mixture subjected to reductive annealing, calcium chloride is added in a ratio of 1: 10-1: 20 with respect to the weight of the annealed oil sludge. 3. Способ по п.1, отличающийся тем, что в выщелачивающий водный и соляной раствор добавляют хлорид кальция в соотношении 1:5-1:20 по отношению к массе выщелачивающегося раствора.3. The method according to claim 1, characterized in that calcium chloride is added to the leaching aqueous and saline solution in a ratio of 1: 5-1: 20 with respect to the weight of the leaching solution. 4. Способ по п.1, отличающийся тем, что количество углерода добавляют исходя из соотношения массы радиоактивного отхода и углерода 1:3-1:5.4. The method according to claim 1, characterized in that the amount of carbon is added based on the ratio of the mass of radioactive waste and carbon 1: 3-1: 5.
