| Abstract: | Based on the research of representative mesoscale numerical simulation methods used in consequence evaluation for nuclear and radiation accidents worldwide, the development plan of numerical simulation software system is established, which is used to finely assess diffusion for the airborne radioactive substances from nuclear accidents happened in China and neighboring areas. The proposed system will adopt the forecasting methods and retrospective analysis methods of meteorological field and diffused field. These methods lay the foundation for the software development and then enhance effectively China＇s nuclear and radiation accident emergency response capabilities. |
