Abstract
The Akkuyu nuclear power reactor (NPP), a new power reactor in the Mediterranean sea coast, which the plant is scheduled to be operational by 2023. In this research, a Lagrangian particle dispersion model HYSPLIT 3.1 was used to predict air dispersion and sea-level deposition of radioactive elements released from a hypothetical accident at Akkuyu NPP. Nuclear Regulatory Commission (NRC) library data was used to compute the source term for this approach. The simulations indicated that volumetric concentration levels exceeding 8.9 E+5 MBq/m3 were observed after fifteen minutes before the accident. The maximum deposition value of 11 MBq/ m2 was found in 1 h intervals at 18 km in the east direction of the site. Also, the trajectory of particle position shows that about 76% of the particles are distributed in the less than 5000 m layers and 26% in the more than 5000 m layers in all simulation time. The TED calculation indicates that the maximum dose (9.8E+1 Sv) occurred in the first day of the accident in 0.5 km of the reactor.
