  • Aiming at the process of uranium material forming radioactive aerosol under the action of explosion load, numerical simulation and experimental research were carried out based on the smoothed particle hydrodynamic method (SPH method). Through the combination of particle dynamics and SPH method, a numerical simulation model of explosive detonation acting on a uranium metal shell was established, which would be used to describe the formation process of uranium aerosol. The specific internal energy of uranium material was used as the aerosol conversion criterion, and the physical process of uranium material conversion into aerosol was obtained. We found two types of damage mode of the uranium under explosive load, one was overall damage when the uranium shell mass was close to the explosive mass, and the other one was crushing damage when the uranium shell mass was much less than the explosive mass. Under the same explosive equivalent, the aerosol conversion efficiencies of uranium materials with different mass were compared with the experimental results. The results show that uranium material can be considered to be completely converted into aerosol when its specific internal energy reaches 1.9 MJ/kg under explosive load. According to the explosive device structure in this paper, when the explosive mass is six times than the mass of uranium, the conversion ratio exceeds 90%. The experimental results have a good agreement with the numerical simulations, which shows that the method used in this paper can accurately describe the aerosol conversion process of uranium materials.
