摘要：
An apparatus and method for chemically digesting low level radioactive, solid waste material wherein the solid waste material is added to an annular vessel (10) substantially filled with concentrated sulfuric acid. Concentrated nitric acid or nitrogen dioxide is added to the sulfuric acid within the annular vessel while the sulfuric acid is reacting with the solid waste. The solid waste is mixed within the sulfuric acid so that the solid waste is substantially fully immersed during the reaction. The off gas from the reaction and the products slurry residue is removed from the vessel during the reaction.
