Study on the Project of Rapid Calculation of Radiation Doses during a Nuclear Accident in Daya Bay Nuclear Power Plant

To investigate the radiation doses quantitatively and rapidly during a nuclear ac ident, the project referred to Daya bay nuclear power plant was implemented, and supposed to get the results rapidly on all representative design basis accidents, some severe accidents and different meteorological conditions. In this study, a rapid calculation method based on the InterRAS program was used to assess the radiation doses. According to the presupposed source terms and real meteorological conditions, the radiation doses could also be shown as a contour format on a map within a radius of 10 kilometers for a more intuitive demand to decision-makers.
