Sažetak
One of the NPP Krško modernization projects is steam generator replacement, during which old steam generators have to be removed and stored on a safe location. Since old steam generators are radioactive a new, special building have to be designed and constructed at NPP Krško site to house the old steam generators, as well as for the storage of non-compactable waste which will be produced during the replacement activities. It is the aim of this paper to estimate the dimensions of the outer walls and of the roof slab for the special building which will satisfy the radiological constraints for the unrestricted areas. Computer code ORIGEN2-PC has been used for activity estimation, while analytical expressions, QAD-CGGP and MCNP code have been used for the radiological shielding analysis. Our results indicate that 70 cm of the concrete for the wall and 60 cm for the roof provide satisfactory shield which limits the dose rates below american standards for level of radiation in unrestricted areas
