摘要： Method and apparatus for conditioning weakly to medium-active wastes through fused vitrification by means of electric electrodes for generating the melting heat. The wastes optionally with additive materials are filled into a cup-shaped melting crucible which contains at least two electrodes. The melting crucible is closed off at the top by a furnace hood which has current leads. Voltage is applied to the electrodes via the current leads until the melting crucible containing material to be melted has melted. The current leads are separated from the electrodes. The furnace hood is removed, and after the cooling down, the melting crucible is filled with inactive cement paste to produce a cover layer.

摘要： Treating weak-to medium-active ion exchanger resins which are dried in a drying container by means of heat and in a vacuum, before they are transported into a storage container, the heat being introduced by heat conduction via the drying container into the ion exchanger resins. The heat is conducted via metallic heat transfer surfaces into the bulk of the resins leaving a core of at most 100 mm thickness. Steam from the moisture in the resin is conducted at the same time into a condenser via a discharge line, with an underpressure of 300 mbar or less.

摘要： For bonding particularly radioactive wastes into a binder, a transporting and mixing device is used which transports the mixture to a storage tank prior to the hardening. The wastes are transported into the mixing zone by gravity and aided by the conveyor helix which also imparts additional wall cleaning action through the dry conveyor zone. A single or multi-component binder is concurrently transported in a direction lateral to the mixing tool to the mixing zone. The mixture is conducted in a straight-line extension of the transport and mixing direction to an outlet to which the storage tank is connected.

摘要： A method and apparatus for drying sewage sludge includes diverting steam escaping during the drying of the sewage sludge and feeding the steam to a compressor. Thermal energy of the compressed and therefore heated steam is supplied to the sewage sludge to be dried through a heat exchanger system. Condensate is drawn off from the heat exchanger system and collected. Thermal energy of the condensate is supplied to the sewage sludge prior to the drying for reinforcing a preliminary degassing.

摘要： A process for the conditioning of contaminated waste through cementing. Dry waste is cemented, especially waste which is recovered as ashes subsequent to the combustion of burnable waste, or as a dry residue during the treatment of sludge. In the process there is added to the dry waste a cement component not less than about 50% by weight of the weight of the waste, wherein subsequent to the admixing of the waste with the cement, there is mixed in water to the cement in a slightly excess stoichiometric ratio of effecting the setting, and the mixture is compacted under pressure and then encased.

摘要： A method and a device are provided for disposing of an aqueous solution that contains an organic acid and an iron complex and occurs particularly in the decontamination of radioactively contaminated surfaces of components. It is contemplated that the iron complex in the solution is reduced by irradiation with UV light. A dissolved iron salt and carbon dioxide, which is given off, are formed in the process. An oxidant is then added to the solution that contains the dissolved iron salt and the organic acid. This produces water, and the iron complex forms once again. Some of the dissolved iron salt is removed from the solution by means of a cation exchanger. The solution containing the iron complex is irradiated again with UV light. A cycle process ensues, which continues until all the organic acid is consumed.
