Spatial Distribution of Hydrogen in NEK Containment
After recent modification NPP Krško is using Passive Autocatalytic Recombiners (PARs) to control concentration of combustible gases. Two of them are declared as safety related (required according to plant’s design basis) and 20 are there to provide additional protection during BDBAs. In order to calculate spatial hydrogen distribution, and predict peak local concentrations, detailed multi-compartment GOTHIC model of NPP Krško containment was developed. Real PAR’s locations are taken into account. Two scoping calculations were performed, one for hydrogen sources in containment during and after design basis LOCA accident (long term behaviour), and another (short term) for MAAP calculated hydrogen source after BDBA SBO sequence. In both situations PARs are able to prevent situations where combustible gases can reach flammable concentrations.
