Simulation and calculation of power plant accidents doses using HotSpot software

Various factors affect the release of radioactive materials in the power plant events including event types, wind speed, air temperature, and so on. In this study, a new model was developed using HotSpot software for calculating doses at different intervals from the site of the incident, and then, this model was simulated and validated using the MCNPX simulator code. Moreover, effective intervals of the dose caused by each radioisotope were measured. The results showed that calculations for determination of doses at different intervals can be obtained using simulation, and as a result, components and other parameters such as buildings or facilities can be added to the simulator and doses were calculated in those cases.
