Shabalin, K. Yaroshenko, O. Marinich, I. Koliabina, N. Mitsiuk, S. Buhera","doi":"10.15407/geotech2021.34.033","DOIUrl":"https://doi.org/10.15407/geotech2021.34.033","url":null,"abstract":"The article is devoted to the study of the barrier properties of bentonite clays from the Cherkasy deposit (Ukraine) as the most promising material for engineered barriers in near-surface disposal facilities for low-level radioactive waste. The work presents a description of the Cherkasy bentonite deposit, in particular, of the most promising II layer of the Dashukivka site, and the composition and properties of the natural and soda-modified (PBA20) bentonites which can be used for safe long-term storage and disposal of radioactive waste. The scanning electron microscope (SEM) images of the samples were made and the chemical and mineral composition of the samples was determined. Based on the obtained data, the Dashukivka bentonite was classified as Al-Fe-montmorillonit. The main rock-forming minerals of the bentonite are montmorillonite (75 ± 3 wt. %) and quartz (20 - 25 wt. %). Infrared spectra of the bentonites in the range of 4000 - 400 cm-1 are typical for dioctahedral Al-smectites and are almost identical both for the natural and modified samples. The derivatographic analysis (DTA) of the bentonite samples allows us to conclude that the modified bentonite PBA-20 has greater thermal stability than the natural bentonite. The total weight loss of the samples is about 10.3% and 17.8%, respectively. From the experimental study of 137Cs adsorption from a simulated ChEZ water solution (mineralization – 0.2 g/dm3), it was found that the equilibrium in the sorbent-solution system is established within 12 to 14 h, and the degree of adsorption on the modified bentonite PBA-20 reaches 93%. The degree of adsorption on the natural bentonite is 7 - 10% lower. Analysis of the partition coefficients (Kd) also indicates a higher efficiency of the Na-modified bentonite compared to the natural, and that ion exchange is the main mechanism of caesium adsorption. Increasing of the pH of the initial solution results only in a slight increase of the degree of adsorption. The degree of 137Cs adsorption on Na-modified bentonite is practically independent of the initial concentration of Ca2+ (from 16 to 160 mg/dm3) and Na+ (from 6 to 60 mg/dm3) in the solution. However, 137Cs adsorption on natural bentonite decreases with the increase in Na+ concentration. Thus, the bentonite clays from the Cherkasy deposit (Dashukivka site, II layer) having good barrier properties can be recommend as anti-migration engineered barriers for radioactive waste repositories, in particular, near-surface storage facilities I and II line of Vector complex","PeriodicalId":52701,"journal":{"name":"Geokhimiia tekhnogenezu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43602188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Precambrian basement metamorphic rocks of the Dniester-Bug, Bug and ultrametamorphic rocks of the Golovanev, Pobuzh, Berdichev and Kirovograd complexes were established. On the southwestern slope of the Ukrainian Shield, 4 uranium occurrences and 4 radioactive anomalies have been discovered, studied and prospected. The uranium occurrences are localized along the regional unconformity surface of the Precambrian basement and platform cover. They are often confined to the nodes of the intersection of faults. The uranium occurrences are installed simultaneously both in the rocks of the basement and in the platform cover. The ore deposits form stockwork and vein segregations among the tectonized rocks of the Precambrian. In the rocks of the sedimentary cover they are discontinuous lenticular, subconcordant with the bedding of rocks. The uranium mineralization is vein-disseminated, represented by uraninite, pitchblende, coffinite, uranium black, casolite, etc. The uranium mineralization was caused by both endogenous and exogenous processes; several stages of uranium concentration have been established. The main source of uranium and associated elements was the low-temperature hydrothermal fluids of the “unconformity zone” faults of the Precambrian basement and sedimentary cover. A comparison is given and the similarity of the uranium mineralization of these occurrences with the rich uranium ores of the \"zones of unconformity\" of the Canadian and North Australian shields is given, which determines the significant prospects for uranium mineralization of the southwestern slope of the Ukrainian shield for the development of the uranium resource base of Ukraine.","PeriodicalId":52701,"journal":{"name":"Geokhimiia tekhnogenezu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48501832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
