Estimation of Dose Rates Around Dry Storage Building During Campaign One Loading in Nuclear Power Plant Krsko

In this paper, neutron and gamma (fuel gamma, neutron induced gamma and hardware activation gamma) dose rates were estimated around the Dry Storage Building (DSB) in Nuclear Power Plant (NPP) Krško during Campaign one loading using MCNP6.2 and ADVANTG3.03 code packages. The Campaign one consists of 16 HI-STORM storage casks filled according to NPP Krsko specific fuel loading plan. The charactersitics of the spent fuel were based on real operating history and their source in terms of neutron and gamma intensity and spectrum were calculated using ORIGEN-S module from SCALE 6.2.4 code package. The annual dose at the closest site boundary and dose rates at the DSB walls are compared with the regulatory limits of 0.05 mSv and 3 μSv/h, respectively.
