Abstract
An issue concerning the management of radioactive waste (RAW) in the Republic of Croatia continuously rises due to the lack of systematic solutions. In this paper, emphasis is being placed on the storage of RAW, as one of the important phases of RAW management. The current RAW storage facilities are not sufficient and there is a need for a new facility for low and intermediate level radioactive waste (LILW), since such waste accounts for the largest part of RAW. For this reason, a preliminary estimate for a one-storey structure was carried out, a potential storage facility of LILW that would be constructed at the location of erkezovac, Trgovska Gora, in the Republic of Croatia, as the currently most prominent location for the realization of the RAW storage facility. The geological characteristics of the site were analysed and, in accordance with the relevant regulations, a static design of the facility was made in the ETABS and SAFE program packages. The construction is a typical reinforced concrete structure, rectangular in plan (10.0 x 30.0 m) with a height of 5.9 m. The selected location meets the given parameters of geological characteristics, while the construction meets the given load and serviceability conditions de ned by Eurocode (ultimate limit state and serviceability limit state). However, a more detailed analysis would be necessary if the decision to construct such a storage facility would be made.
Highlights
Radioactive waste (RAW) is the product of technology with processes using radioactivity or ionising radiation
According to the list of hazardous sources of ionising radiation published by the State Of¿ce for Radiological and Nuclear Safety, there are 38 currently registered locations with activities using radioactive sources, using a total of 133 sources in all four categories (State Of¿ce for Radiological and Nuclear Safety, 2017)
This is signi¿cantly less compared to the 510 institutions and organizations registered for authorised use of ionising radiation sources in 1992 (Subašiü et al, 1992), the problems of RAW management in our country become more and more important due to the lack of systematic solutions
Summary
Radioactive waste (RAW) is the product of technology with processes using radioactivity or ionising radiation. There are two temporary storage facilities for low and intermediate level radioactive waste (LILW) in the Republic of Croatia, located within the Institute for Medical Research and Occupational Medicine and the Ruÿer Boškoviü Institute. They are closed for accepting new waste. The expected bedrock permeability is low (Milling, 2017)
