Abstract

U diplomskom radu opisan je koncept odlaganja visoko radioaktivnog otpada i istrošenog nuklearnog goriva u duboke geološke formacije, razvijen u cilju sigurne i dugoročne izolacije radionuklida te zaštite ljudi i okoliša od negativnog radiološkog utjecaja. Pri izgradnji dubokog geološkog odlagališta primjenjuje se najbolja tehnologija te iskustva stečena u projektima vodećih nuklearnih programa. Za potrebe ovog rada izrađen je numerički model u programu Plaxis2D koji simulira širenje topline iz spremnika u odlagalištima istrošenog nuklearnog goriva. Za izradu su korišteni podaci in-situ mjerenja toplinskih karakteristika stijenske mase i inženjerskih barijera. Podaci su analizirani, a rezultat predstavljen u radu.

Abstract (english)

This thesis describes the concept of high radioactive waste and spent nuclear fuel disposal in deep geological formations, developed for the purpose of safe and long-term isolation of radionuclides and protecting people and the environment from negative radiological impacts. The high technology and experience gained in the projects of leading nuclear programs are applied in the construction of a deep geological repository. For the purposes of this paper, a numerical model was developed in the Plaxis2D program, which simulates the spread of heat from a disposal canister in a spent nuclear fuel repository. In-situ measurement data of thermal characteristics of rock mass and engineering barriers were used for the construction. The data were analyzed, and the result was presented in the paper.
