Abstract

U diplomskom radu opisan je koncept odlaganja visoko radioaktivnog otpada i istrošenog nuklearnog goriva na temelju poznatih svjetskih programa konačnog odlaganja u duboko geološko odlagalište. Koncept dubokog geološkog odlagališta radioaktivnog otpada koji bi osigurao dugoročnu izolaciju radionuklida i zaštitu ljudi i okoliša još uvijek nije realiziran ni u jednoj zemlji, za razliku od zbrinjavanja nisko i srednje radioaktivnog otpada. U radu je analiziran pojam korozije metala te mehanizmi i uzroci oštećivanja i propadanja metalnih konstrukcija (spremnika radioaktivnog otpada) u geološkoj sredini. Opisana je korozija bakra i čelika od kojih će se izrađivati spremnici za istrošeno nuklearno gorivo, a navedena su svojstva i uloga bentonitne gline koja će služiti kao inženjerska barijera u dubokom geološkom odlagalištu. Opisani su uvjeti u odlagalištu i korozija koja nastaje u tim uvjetima dubokog geološkog odlagališta.

Abstract: The concept of disposal of high radioactive waste and spent nuclear fuel described in this paper is based on world famous programs for final disposal in a deep geological facility. The concept of deep geological radioactive waste that would ensure long-term isolation of radionuclides and protect people and the environment is still not implemented in any country, in contrast to the disposal of low and intermediate level radioactive waste. This paper analyses the concept of corrosion and the mechanisms and causes of damage and deterioration of metal structures (canister of radioactive waste) in the geological environment. The corrosion of copper and steel containers for spent nuclear fuel is described, as well as the properties and the role of bentonite clay, which will serve as the engineering barriers in deep geological repository. Conditions in the landfill and corrosion that occurs in these conditions of deep geological repository are described.
