The invention relates to an apparatus for treating waste material including organic components and radioactive agents. In the apparatus the waste material including organic components and radioactive agents are gasified at temperature between 600-950° C. in a fluidized bed reactor to form a gaseous material. The gaseous material is than cooled in a water quenching device so that temperature is between 300-500° C. after the cooling. The solid fraction including radioactive agents is removed from the gaseous material in a in at least one filtration device. A gas scrubbing device then removes sulphur by scrubbing the treated gaseous material after the filtration in order to form a treated gaseous material.

A basket for incinerating waste inside an incinerator for a duration longer than fifteen minutes with no need for waste to be molten earlier, particularly when waste is introduced inside the incinerator. The basket includes mainly of a glass fiber envelope: it is preferably stiffened by a lightweight metal structure located inside or outside the envelope or built into it. A gripping handle is installed on top of the assembly that is stiffened at the top by a metal tube to which a lightweight metal structure is fixed and by a base formed from a drip pan fixed to the base of the lightweight metal structure.

The present invention relates to a method for treating waste material comprising organic components and low and/or intermediate level radioactive agents. The method comprises adding material comprising fibers and kaolin to the waste material in order to form a starting material, and gasifying the starting material at a temperature between 600 and 950° C. to form a gaseous fraction and a solid fraction comprising low and/or intermediate level radioactive agents, gasification residues of the organic components and metakaolin. The present invention also relates to a use of mate-rial comprising fibers and kaolin.

The invention provides a system for pyrolysing organic waste. The system comprises a conical housing (4) configured to temporarily, substantially hermetically, enclose the waste and a mixing device provided with a drive shaft rotatably mounted relative to the housing and a conical mixing body (25) configured inside the housing to fluidise the waste, which mixing body fixedly attached substantially does not touch the housing. The system further comprises heating means (24) for heating the side wall of the housing. This system makes it possible to carry out the processing of organic waste in a batch process. The mixing body prevents a portion of the waste from sticking together by fluidising the waste and keeping it fluidised, whereby the heat generated by the heating means can gradually spread through the waste inside the housing.

The present invention provides a method for synergistically vitrifying medium and low-level radioactive glass fibers and combustible solid nuclear waste incineration ashes. According to the chemical composition characteristics of incineration ashes of combustible solid wastes such as glass fibers, cotton, plastic, rubber and absorbent paper produced during the operation of nuclear facilities, the present invention takes the glass fibers as a glass matrix of combustible waste incineration ashes and minimizes the addition of an additive by a combination in different proportions through a synergistic treatment method. A vitrified form provided by the present invention meets the requirements of uniformity, density, impact resistance, chemical durability and the like of radioactive waste vitrified forms.

Provided herein is a method for reducing radiologically-contaminated waste. The method comprises treating radiologically-contaminated surfaces, wherein the radiologically-contaminated surfaces are treated with a surface treatment agent; treating radiologically-contaminated subsurfaces, wherein the radiologically-contaminated subsurfaces are treated with a surface/subsurface treatment agent; consolidating soil waste; employing real-time scanning technology to classify waste, wherein the classifying is based at least in part on a threshold of radiological contamination, and wherein the classified waste is sorted based on the classification; and disposing of the waste via at least one of different disposal routes, based at least in part on the classification.
