Methods for processing metal components from the nuclear industry are described. In some embodiments, a method includes processing a component having a surface contaminated with radionuclides by dissolving at least a portion of the surface with an acid solution to produce a waste solution including the radionuclides, and separating the radionuclides from the waste solution. In some embodiments, a method includes processing a component including a target radionuclide by immersing at least a portion of the component in an electrolyte bath, applying an electric current to cause electrodissolution, and electroplating the target radionuclide from the solution onto a cathode. In some embodiments, a method includes processing a metal composite component by dissolving it to produce a solution including dissolved metal and particulate material, and separating the particulate material.
Methods are provided for separating radioisotopes from spent ion exchange resins used to process nuclear waste. In some embodiments, the resin is contacted with an aqueous solution including one or more acids to elute the radioisotopes into an enriched solution. In some embodiments, the resin is contacted with an aqueous solution including one or more salts, such as a sulfate or nitrate salt solution, to elute the radioisotopes into an enriched salt solution. The enriched solution can include at least 80%, or at least 95%, of the activity of radioisotopes such as Sr-90, Co-60, Ni-63, Cs-137, C-14, Co-58, and/or Mn-54 originally present in the resin. In some embodiments, a mixed bed resin is separated into cation and anion components, and the anion resin is treated to release C-14 as carbon dioxide gas which is captured and purified to obtain a C-14 product.

Methods for recycling metals from nuclear industry components are described. In some embodiments, the methods include removing metal contaminated with radionuclides from a metal component, resulting in a contaminated solution containing the radionuclides, and separating the radionuclides from the contaminated solution. The metal removal can be performed mechanically, chemically, and/or electrochemically. The radionuclides can be separated using techniques such as ion exchange, solvent extraction, precipitation, coprecipitation, and/or electrochemical deposition. Waste materials generated during the recycling process can be reused in subsequent recycling steps. The methods allow the recycling of valuable metals from nuclear industry components while minimizing radioactive waste and allowing the beneficial reuse of recovered radionuclides.

Method of using a modular container system for radioactive waste
A packaging system for radioactive waste is robust, highly functional, and can be used for nearly all radioactive waste streams that require shielded packaging. The packaging system includes a modular container that is configured to receive modular shielding inserts. The packaging system can be used to store, transport, and dispose of radioactive waste.
Methods for filling a container with hazardous waste are disclosed. One method includes moving the container to a position where a filling head adds solid hazardous waste to the container, coupling a lid to the container to close the container while the container is at the position, and moving the closed container away from the position. Another method includes aerating dry cementitious material in the container with a mixer, adding hazardous waste to the container, mixing the cementitious material and the hazardous waste with the mixer, and controlling the speed of the mixer.

A method and apparatus for treating radioactive waste water containing contaminating ions, colloids and suspended solids having like (usually negative) charges preventing their precipitation. An electric current is passed through the waste water in an EC assembly to cause electro-coagulation of the contaminants and anodes of this assembly are made of a metal that dissolves to provide cations for neutralizing the negative charges and forming precipitates containing neutralized contaminants. Precipitates are then separated from waste water by an electro-magnetic or other filtering unit. The water pH and conductivity may be adjusted before the EC assembly and additives may be introduced into its effluent for enlargement of precipitate particles, improvement of filtration, improvement of dewaterability, and/or enhancement of magnetism.
