Description

Technical Field

[0001] The present invention relates to the technical field of isotope separation, and more particularly to a method and system for simulating separation of isotope light components. Background Art

[0002] Isotope separation is the study of the separation between different isotopes of the same element. The separated isotopes should belong to the same element with the same atomic number, such as the separation of 235U and 238U, and the separation of 1H, 2D and 3T.

[0003] Isotopes have two main uses. One is as materials for the atomic energy industry, and the other is as tracer atoms, which are widely used in agricultural science, medicine, pharmacology, biology, life science, and environmental protection. Various isotopes of the same element have the same number of protons in the nucleus and the same number of electrons outside the nucleus, so their chemical properties are very similar and difficult to separate. However, they have different numbers of neutrons in the nucleus, and therefore different atomic weights, which causes differences in the thermodynamic properties of isotopes or their molecules. The purpose of separation can be achieved by utilizing the subtle differences in the physical and chemical properties of isotopes. The main methods of isotope separation are: electromagnetic separation, centrifugation, diffusion, thermal diffusion, electromigration, molecular distillation, rectification, chemical exchange, extraction, absorption, adsorption, chromatography, ion exchange, crystallization, etc. Among them, chemical exchange and rectification are particularly suitable for isotope separation of light elements.

[0004] With the continuous development of science and technology, the demand for isotopes in various fields of society is also increasing day by day. Under this circumstance, it is particularly important to find an efficient and simple method to separate isotopes. However, considering the complexity and time-consuming nature of the isotope separation process in reality, as well as the cost of experimental equipment, there are still many limitations on the development and research of isotope separation experiments. Therefore, it is necessary to provide an isotope separation simulation method and system to simulate the isotope separation process, better assist researchers in conducting isotope separation research, and find an efficient and simple separation method.
