摘要：

This work aims to model a potential consequence after the release of radioactive material from the inventory of a PWR nuclear reactor in a case of an event known as steam generator tube rupture (SGTR). Such a release contains the radioactive materials forming the contamination plume simulated by the software HotSpot. The event simulation was performed varying the atmospheric stability state. The radiation dose was then evaluated in its contribution to the radiological risk through the BEM V equations. The results were taken in a timely manner offering flexibility for the early stage decision-making. Furthermore, the findings suggest that the atmospheric stability impacts the risk evaluation due to its influence to the radiation dose, which in turn is a key parameter for the risk evaluation. At last, it is expected that the findings from this work encourage further studies aimed to model consequences for a SGTR event. (C) 2019 Elsevier Ltd. All rights reserved.
