Variation of doses with classes of atmospheric stability and wind speed in a DBA scenario

Abstract

The safety analysis implements studies that consider the hypothetical occurrence of accidents in nuclear or radioactive installations, simulating as a consequence, the release of radioactive material into the atmosphere. Atmospheric dispersion models to estimate the behavior of the radioactive plume are implemented, including important estimates of the radiological impact on the public. In this work, the influence of atmospheric stability and wind speed on the transport of a radioactive plume generated by a hypothetical loss of refrigerant in a generic PWR was analyzed and the radiological impact on the public exposed to the plume was studied.
