Background
The nuclear industry generates a large amount of waste each year during its development, which can be classified as radioactive contaminated ion exchange media, sludge, organic waste liquids, dry miscellaneous organic waste, etc. This waste will be disposed of in various ways before it is disposed of in the bedrock room or by shallow land. These wastes are large in volume, complex in composition and difficult to handle, and in the treatment of radioactive organic wastes, they result in an increase in volume and consequently in storage costs.

Besides pyrolysis incineration, the treatment processes of other technologies are all mechanical and physical processes, the volume reduction effect is common, while pyrolysis incineration is only used for treating low-level combustible waste, and the treatment objects are limited. Therefore, there is a need for an apparatus which can reduce the volume and chemical activity of the waste to be treated, i.e. realize the effects of volume reduction and effective waste treatment.

The method has a remarkable volume reduction effect, the volume of the waste can be reduced to 1/10-1/5 before treatment, secondary pollution is avoided in the treatment process, and the synthetic gas generated after cracking can be converted into N after treatment2、CO2And water, basically no waste liquid is generated, and the method is safe and pollution-free. In the fluidized bed steam reforming reaction furnace, radioactive organic wastes are cracked, and simultaneously, various reactions of different types such as a water-gas shift reaction, an oxidation reaction, a reduction reaction, a mineralization reaction under the action of an additive and the like also occur. These reaction processes are coupled with each other, and once the fluidized bed reactor is not well controlled, local hot spots or sticky substances are easily formed to cause agglomeration of fluidized particles, the fluidization quality and the reaction effect are slightly influenced, and the shutdown is caused if the fluidized bed reactor is not well controlled.
