Atomic vapor laser isotope separation (atomic vapor laser isotope separation) process mainly includes the metal atomization process, the target atom in the vapor atom of the ionization process and the target isotope ion extraction process. In order to further understand the mechanism of atomic vapor laser isotope separation, this paper reviews the current theoretical research (especially numerical simulation) of each sub-process in atomic vapor laser isotope separation system, including the description of heat transfer and flow in the crucible during atomization Characteristics of the liquid model and the liquid metal evaporation expansion process of Monte Carlo particle simulation or based on the Bhantagar-Gross-Krood (BGK) equation of the dynamic method to describe the laser photoionization process of classical rate equations and semi-classical theory and ion extraction process Electron balance fluid model and Monte Carlo particle simulation method. The main progress and the need for further work on the separation of atomic vapor laser isotopes using the above methods are reviewed. This will provide some reference for further study in this field in the future. effect.
