In the field of atomic energy, centrifugal extraction test plays a crucial role, from the preparation of atomic energy purity raw materials required for nuclear reactors, to the reprocessing of nuclear fuel, as well as the treatment of high-level waste liquid, can not be separated from the application of centrifugal extraction equipment. Due to the significant advantages of small retention and short residence time, the centrifugal extractor can effectively deal with the radiation degradation of organic solvents under strong radiation field and ensure the safety of nuclear geometric criticality.

In the laboratory, the rotor diameter of a single stage centrifugal extraction test equipment is usually between 10 and 70 mm, the mixing flux varies from 0 to 80 liters per hour, and the speed range can be 0 to 5600 revolutions per minute. In order to improve the accuracy and effect of the test, multiple single-stage centrifugal extractors are usually connected in series to form a countercurrent extraction system. For example, in nuclear reactors, zirconium and hafnium are key materials, and through 26 stages of pickling, extraction, washing and stripping processes, zirconium and hafnium can be efficiently separated, and finally zirconium and hafnium products with atomic purity can be produced.

The application of centrifugal extraction test in the field of atomic energy is not only limited to the preparation of nuclear reactor materials, but also involves the treatment and management of nuclear waste. A large amount of radioactive waste will be generated after the use of nuclear fuel, and the safe disposal of these wastes is an important issue in the application of nuclear energy. Due to its high separation capacity and low solvent residue characteristics, centrifugal extraction technology provides an effective solution for the treatment of these high-level waste liquids. By precisely controlling the parameters in the centrifuge extraction process, scientists are able to effectively separate the radioactive isotopes in the waste liquid, reduce the radioactive intensity of the waste, reduce environmental risks, and support the safe storage and disposal of the waste. The innovative application of this technology not only improves the efficiency of nuclear waste disposal, but also contributes to the sustainable development of nuclear energy.

In the application of atomic energy, the advanced nature of centrifugal extraction technology is reflected in its ability to effectively cope with extreme operating conditions. The high radiation environment in a nuclear reactor places extremely high requirements on equipment and materials, and traditional extraction methods may not be able to meet these requirements. Due to its high speed and short residence time, the centrifugal extractor can maintain stable working performance under strong radiation field, and reduce the degradation of organic solvents under radiation. The application of this technology not only improves the purification efficiency of nuclear materials, but also ensures the safety of nuclear reactor operation.

Especially when dealing with waste liquid with extremely high radioactivity, centrifugal extraction technology can effectively avoid potential safety hazards and provide a solid guarantee for the safe operation of the nuclear energy industry. The continuous innovation and optimization of this technology has opened up a broader development space for the research and practical application in the field of atomic energy.
