Description

Technical Field

[0001] The utility model relates to the technical field of radioactive waste liquid solidification treatment, in particular to a leakage-proof radioactive waste liquid solidification material sampling tool. Background Art

[0002] Solidification of radioactive liquid waste is a process of converting radioactive liquid waste or its concentrate into a solid form. The basic requirements include stable physical and chemical properties of the solidified body, sufficient mechanical strength, large volume reduction ratio, low leaching rate in water, simple and easy operation process, and low treatment cost. Through solidification treatment, the direct pollution of radioactive waste to the environment can be reduced while ensuring the safe storage of radioactive materials. After the radioactive waste liquid is solidified, sampling tools are needed to sample the solidified radioactive waste liquid product.

[0003] However, traditional sampling tools have the following disadvantages:

[0004] Traditional sampling tools use their own clamps to clamp the radioactive waste solid from both sides for sampling. During the sampling process, radioactive impurities on the radioactive waste solid are prone to leakage, which reduces the safety of sampling the radioactive waste solid. Utility Model Content

[0005] The purpose of the utility model is to provide a leakage-proof radioactive liquid waste solidified material sampling tool, so as to solve the problem proposed in the above-mentioned background technology that the traditional sampling tool uses its own clamping plates to clamp the radioactive liquid waste solidified material from both sides for sampling, and radioactive impurities on the radioactive liquid waste solidified material are easily leaked during the sampling process, thereby reducing the safety of radioactive liquid waste solidified material sampling.
