| Popis: | U radu je opisan koncept odlaganja istrošenog nuklearnog goriva i visoko radioaktivnog otpada u duboke geološke strukture čija je zadaća zaštititi okoliš od negativnog i dugotrajnog utjecaja radijacije. Odlaganje takve vrste otpada predstavlja ozbiljan inženjerski problem u svim zemljama s nuklearnim energetskim programom, a koncepti odlagališta se kontinuirano razvijaju i nadopunjuju. Za potrebe ovog rada napravljen je matematički model u programu FLAC koji prati širenje topline u odlagalištu kao i mehaničke deformacije geološke sredine. Model predstavlja odlaganje istrošenog nuklearnog goriva u bakrenom spremniku, s bentonitnom glinom kao dodatnom inženjerskom barijerom, aksijalno postavljenima u odlagališnom tunelu u granitu kao geološkoj sredini. Rezultati su analizirani i predstavljeni u radu. The concept of the disposal of spent nuclear fuel and highly radioactive waste in the deep geological structures, whose task is to protect the environment from the negative and long-lasting effects of radiation, is presented in thesis. Disposal of this type of waste represents serious engineering problem in all countries with nuclear energy program, and disposal concepts are constantly developed and improved. A mathematical model was developed in the FLAC program which tracks the spread of heat and mechanical deformations in the repository. The model represents the disposal of spent nuclear fuel in a copper cask, with bentonite clay as an additional engineering barrier, axially positioned in disposal tunnel within the granite as geological environment. The results are analysed and presented in the thesis. |
