Radiation Dose Rates in the Vicinity of the NPP Krško Spent Fuel Pool

Our recent analysis showed that from the criticality standpoint of view it is possible to increase capacity of the NPP Krško spent fuel pool by reracking to accommodate spent fuel assemblies for plant lifetime. The reracking will also effect the radiation dose rates in the vicinity of the NPP Krško spent fuel pool. In this paper we have investigated the radiological impact of reracking using SAS sequences of the SCALE code system. Gamma and neutron dose rates are calculated at different positions close to the spent fuel pool surface for current and reracked spent fuel pool configuration. A comparison of the calculated dose rates and the dose limit in 10 CFR 20 for the restricted work area has been performed.
