AB  - The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as the subject of its investigation: the cement matrix formulation, the water/ cement ratio, the amount of waste, and the porosity of such a structure. Implementing the standard leaching method by Hespe the possibility of comparing different authors’ results was achieved. Diffusion and semi-empirical model were used to investigate the transport phenomenon in order to predict the leaching level for a long period of time. Leaching of Co2+ and Cs+ ions under dynamic conditions immobilized in the cement matrix dynamic conditions decreases with the increase of the sludge content, regarding porosity increase. The effects of the diffusion and surface washing are equalized, and the contribution ofthe matrix dissolution to the Cs + and Co2+ transport in the cement porous media increases, on average, for one order of magnitude. The semi-empirical model gives a better approximation for Co2+ and Cs+ leaching process for the duration ofthe experiment while both models significantly approximate leaching results in dynamic conditions. © 2019, Vinca Inst Nuclear Sci.

AB  - The sorption properties of waste facade, brick, and asphalt sample towards Sr(II), Co(II), and Ni(II) ions from single and multicomponent solutions were investigated. The highest sorption capacity was found for Ni(II) ions, while the most effective sorbent was facade. Simplex Centroid Mixture Design was used in order to investigate the sorption processes of ions from solutions with different composition as well as the competition between the cations. Based on the statistical analysis results, the equations for data modeling were proposed. According to the observations, the investigated solid matrices can be effectively used for the liquid radioactive waste treatment. Furthermore, the applied methodology turned out to be an easy and operational way for the investigations of multicomponent sorption processes.

AB  - The aim of the study was to estimate if dust/fly ash emitted into the atmosphere from chimneys and the ash disposal sites of the thermal power plants Nikola Tesla A and B in Obrenovac could increase the concentration of PM10 in New Belgrade. TNTA and TNTB are close to Belgrade (population of 2.5 million) and it is important to estimate the amount of the pollution emitted into the atmosphere from these sources. The pollution from chimneys is estimated from yearly amounts of discharge, while the lifting of ash/coal dust was parameterized by the model. The used model is the straight-line Gaussian plume model written in the Fortran programming language. The first estimation was done using mathematical modeling for the idealized situation with prescribed winds and stability. The second estimation was done using the observed meteorological data for the whole year of 2009. With strong winds (over 40 km/h), dust will reach Belgrade in dozens of minutes, while during moderate winds (similar to 10-30 km/h), it would take about one hour to reach it. In these cases atmosphere is close to the neutral stability class. In case of weaker winds and stable atmosphere, the increase of air dust concentration in Belgrade would start after a few hours (6-10). Regarding the other two sources of pollution, coal handling piles and ash deposit sites, during strong winds ( GT 40 km/h) and neutral stability, fly ash would reach Belgrade in several dozen of minutes.

AB  - Predmet istraživanja ove doktorske disertacije je izučavanje uticaja ulaznih podataka na polja koncentracija zagađujućih materija u donjem graničnom sloju atmosfere dobijenih primenom matematičkih modela kao i usložnjavanje matematičkog modela atmosferske disperzije Gausovog tipa, čiji je rezultat generalisan Gausov disperzioni model. Cilj istraživanja u ovom radu je realizacija i primena kompleksnog matematičkog difuzionog modela, koji uzima u obzir složene atmosferske procese u sloju mešanja, kao i razrađena procedura za pripremu ulaznih podataka, koji omogućavaju praćenje rasprostiranja zagađujućih materija u okolini industrijskih i nuklearnih izvora na rastojanjima do 10-20 km, gde su koncentracije zagađujućih materija iz tih izvora obično najveće i gde se dobijaju prve informacije važne za ranu najavu akcidenata i pokretanje kontramera. Pored navedenog cilj je i verifikacija matematičkog modela pisanog u FORTRAN programskom jeziku (NFS-Vinca) preko meteoroloških podataka koji su dobijeni u realnom vremenu, kao i procena rasprostiranja polutanata na osnovu idealizovane situacije sa zadatim vetrom i klasama stabilnosti.Istraživanja u okviru doktorske disertacije polaze od hipoteze da koncentracije zagađujućih materija koje se emituju u atmosferu iz veštačkih izvora zavise od karakteristika izvora, atmosferskih procesa u donjem graničnom sloju atmosfere, tzv. sloju mešanja, karakteristika tla i fizičko hemijskih karakteristka zagađujućih materija. Kod nuklearnog postrojenja modelovana je koncentracija radioaktivnosti u vazduhu sledećih radionuklida: 137Cs, 90Sr, 60Co, 154Eu. Kod industrijskog postrojenja određivan je nivo koncetracije PM10.U prvom delu rada, matematičkim modelom su dobijene prosečne godišnje koncentracije aktivnosti u vazduhu, koncentracije suve i vlažne depozicije kao i ukupna godišnja doza koju bi primio hipotetički stanovnik u blizini nuklearnog reaktora. Rezultati modelovanja su upoređeni sa vrednostima koncentracije radioaktivnosti iz IAEA (International Atomic Energy Agency) literature za dati scenario radionuklida. Zbog male razlike u rezultatima, model predstavljen u radu može da se koristi kao osnova za ovu vrstu analize. Izračunato je da maksimalna vrednost za ukupnu dozu koju bi primio hipotetički stanovnik u okolini nuklearnog reaktora za godinu dana iznosi 7.3 μSv, što je manje od granične vrednosti koja iznosi 10 μSv...
AB  - The subject of this doctoral dissertation was the influence of the input data on the pollutant concentration in the lower atmospheric boundary layer obtained by mathematical model, which was the result of generalized Gaussian dispersion model. The aim was implementation of complex mathematical diffusion model and development procedures which enable the monitoring of dispersion of pollutants in the environment of industrial and nuclear power plants within 10-20 km, where the concentration of pollutants from these sources is usually the highest, and also for early warning for accidents and countermeasures. In addition is the verification of the mathematical model in FORTRAN programming language (NFS-Vinca) through meteorological data obtained in real time, as well as the evaluation of dispersion of pollutants on the basis of idealized situations specified with wind classes and stability.Research in this dissertation is based on the hypothesis that the concentrations of pollutants emitted into the atmosphere from artificial sources depend on the characteristics of the sources of atmospheric processes in the lower atmospheric boundary layer, soil characteristics and the physical and chemical characteristics of pollutants. For the nuclear power plant, radioactivity concentration of the following radionuclides 137Cs, 90Sr, 60Co, 154Eu was determined. For thermal power plant the concentration level of PM10 was measured.The air pollution dispersion model is based on average annual activity concentration in the air, deposition on soil and field of total annual dose to a hypothetical resident contaminated by air in the vicinity of a nuclear reactor. The results of modeling were compared with values from an IAEA publication for a given scenario of radionuclide emission to the atmospheric boundary layer. Due to small differences in the results, compared to the IAEA recommended model, the model presented in the thesis can be used as a basis for this type of analysis. The maximum value of the total annual dose to a hypothetical resident was 7.3 μSv which is less than the limit value of 10 μSv...

AB  - Research activities of Vinca Institite have been based on two heavy water research reactors: a 10 MW one, RA, and zero power, RB. Reactor RA was operational from 1962 to 1982. In 2010, spent fuel has been sent to the country of origin, and the reactor now is in decommissioning. During the operational phase of the reactor there were no recorded accidental releases into the environment, only operational ones. Results of the environmental impact assessment of the assumed emission of radionuclides from the ventilation of nuclear reactor RA in Vinca to the atmospheric boundary layer are presented in this paper. Evaluation was done by using the Gaussian straight-line diffusion model and taking into account characteristics of the reactor ventilation system, the assumed emission release of radioactivity (from the literature), site-specific meteorological data for six-year period and local topography around nuclear reactor, and corresponding dose factors for inventory of radionuclides. Based on the described approach, and assuming that the range of appropriate meteorological data for six year period for the application of described mathematical model is enough for this kind of analysis, it can be concluded that the nuclear reactor RA, in the course of its work from 1962 to 1982, had no influence on the surrounding environment through the air above regulatory limits.

AB  - This paper presents an algorithm for the calculation of internal and external doses as an integral part of the mathematical model of atmospheric dispersion. The air pollution dispersion model is used on average annual activity concentration in the air, deposition on soil and field of total annual dose to a hypothetical resident contaminated by air in the vicinity of a nuclear reactor. The results of modeling were compared with values from an IAEA publication for a given scenario of radionuclide emission to the atmospheric boundary layer. Due to small differences in the results, compared to the IAEA recommended model, the model presented in the paper can be used as a basis for this type of analysis.
