Sažetak
Passive Containment Filtered Vent (PCFV) was installed in Nuclear Power Plant (NPP) Krško in 2013 as a part of safety upgrade program. It is intended for severe accident consequences prevention and mitigation by ensuring the containment integrity. When the pressure in the containment reaches limiting value, the containment atmosphere is released in the environment through the PCFV system exhaust line. But, before release in the environment, the containment atmosphere passes through five aerosol filters in containment and an iodine filter in the auxiliary building to reduce isotopic activity. In this paper, dose rates around the exhaust line of the PCFV system resulting from radioactivity release in case of a severe accident are determined. The assumed severe accident scenario is a beyond design basis station blackout (SBO) in NPP Krško, which is simulated by using the MELCOR code. Its results are input for the radiological calculations to obtain the activities released in the containment. The obtained activities are then transformed into the gamma source intensity and spectrum using the ORIGEN-S libraries. This form of the source term is required for the Monte Carlo calculations. The source is present in the containment and in the PCFV duct. The dose rates around the duct are calculated using MCNP6.2 code.
