Abstract

The invention relates to a radioactive organic waste liquid solidification device and method. The device comprises a motor, a bracket, a stirring shaft, a stirring paddle, a solidification kettle, a fixing frame and a discharging valve. The method comprises the following steps: 1, adding a certain amount of radioactive organic waste liquid into a solidification kettle at room temperature; and 2, under the condition of continuous mechanical stirring, adding a thickening agent, wherein the stirring speed is 45-55 rpm, the stirring time is 45-60 min, and the organic waste liquid becomes dark in color, is not clear any more, but still has good fluidity. According to the invention, the problem of radioactive organic waste liquid solidification is solved, and the device has the advantages of compact structure, stable operation, convenient operation, good product solidification effect and the like.

Description

technical field [0001] The invention belongs to the technical field of radioactive liquid waste treatment and disposal, and in particular relates to a device and method for solidifying radioactive organic waste liquid. Background technique [0002] The treatment of organic waste liquid contaminated by radionuclides is a difficult problem often encountered in the decommissioning of nuclear facilities and the treatment of radioactive waste. my country's standards for the transportation of radioactive materials have very strict requirements on the transportation of dispersible radioactive waste. The transportation of radioactive waste oil is difficult and costly, and there are great potential safety hazards; once leakage occurs during transportation, it is very easy to cause oil pollution And the proliferation of radioactive substances, the difficulty of recycling and processing, the consequences are unimaginable. In order to ensure the safe transportation of radioactive organi...
