Level 3 PSA application for Akkuyu nuclear Power plant

During severe accidents in nuclear power plants, containment may fail and radioactive isotopes may release into atmosphere. As a result of meteorological conditions and atmospheric dispersion of radioactive isotopes, radiation may reach to public. Urgent and early protective actions are implemented to protect public from the effects of radiation. Level 3 probabilistic safety assessment (PSA) produces data to implement appropriate protective actions and to plan on-site and off-site emergency response actions. In this study, Level 3 PSA application was performed for Akkuyu Nuclear Power Plant (NPP) in Turkey. For calculations, releases from all possible exposure pathways and a period of one year for the residence at the associated distances were taken into account. RASCAL 4.2 was used for the analysis. Results were used to validate the dose values presented in the Environmental Impact Assessment (EIA) Report.The results of the study show that at the distances farther than three kilometers, estimated dose values for public exposure were within acceptable limits (5mSv/year) and in good agreement with the values presented in the EIA report.
