Abstract

U radu su opisana i provedena tri ispitivanja prešane bentonitne gline. Također, prikazan je proces pripreme uzoraka i izrade potrebne aparature. Cilj rada bio je odrediti srednju vrijednost propusnosti, poroznosti i jednoosne tlačne čvrstoće pripremljenih uzoraka te kritički ocijeniti mogućnost primjene istih u odlagalištu visoko radioaktivnog otpada. U ispitivanju je korišten prah natrijskog bentonita komercijalnog naziva Saline seal 100 poljske tvrtke Cetco. Ispitivanja su provedena u dva laboratorija, laboratoriju za petrofiziku i ležišne fluide RGNF-a i geomehaničkom laboratoriju tvrtke Geokon-Zagreb. Na temelju rezultata istraživanja zaključeno je da se materijal može koristiti za ugradnju u odlagalište istrošenog nuklearnog goriva.

Abstract (english)

Abstract: Three examinations of compacted bentonite clay were conducted. Also, the sample making procedure is shown and thoroughly explained. The aim was to determine the average value of permeability, porosity and one axial compressive strength and to a critically value measured data in case of building material in final repository. In this laboratory testing the material used was a powder of sodium bentonite clay commercially known as Saline seal 100 produced by polish company Cetco. Testings took place at two laboratories, petrophysical laboratory at RGNF and the geo-mechanical laboratory of the company Geokon-Zagreb. After testings it is concluded that the material tested is an acceptable option for building in final repository for spent nuclear fuel.
