Abstract:

Introduction: Uranium hexafluoride (UF6, UHF) is a gaseous product containing uranium and fluorine. Once in the air, it interacts with water vapor and produces hydrolysis products that can penetrate the human body and lead to the chemical effects of uranium and fluorine, as well as the radiation effects of uranium on the body. This action can be very strong and therefore serious attention has been paid to its study for a long time. Purpose: Quantitative calculation of the radiation effects of uranium on humans and their analysis in the conditions of daily work at nuclear power plants, as well as in emergency situations. Material and methods: We consider uranium hexafluoride that appears under certain conditions in the air of the working rooms of some enterprises and describes methods for describing the distribution of UHF hydrolysis products to objects that can sense their effects. All these methods are combined into a single integrated model. The analytical expressions obtained in the framework of this model at various stages are given, which make it possible to calculate the radiation effect of UHF. Results: The calculated values of the characteristics of the radiation exposure are given, their analysis is carried out. The conditions are formulated under which there is a danger of serious radiation exposure of uranium hexafluoride to employees of nuclear power plants during everyday work and in emergency situations. Conclusion: Based on all the material presented, it is concluded that the constructed mathematical model reliably describes the event in question and allows us to calculate the radiation effect of uranium on humans.

Abstract:

We propose a double cascade scheme for reducing the concentration of232, 234, 236U isotopes in regenerated uranium hexafluoride. In the product of the first ordinary cascade the greatest decrease in the236U /235U mass ratio with enrichment in235U to a concentration of less than 20% is provided. To ensure the required concentrations, a special mode of operation of the stages. In the second ordinary cascade, which is fed by the product of the first, enrichment in isotopes232,234U is performed. The waste flow, purified from232, 234U, is diluted to a concentration of235U less than 5%. A method for calculating the parameters of cascades with stage separation factors corresponding to gas centrifuges is presented. A computational experiment was carried out on its basis. It was shown that the product obtained after dilution with respect to isotopes232, 234U meets the requirements of the ASTM C996-20 specification for the low-enriched commercial grade of uranium hexafluoride. The content of236U in it is several times lower than in the case of direct enrichment of regenerated uranium hexafluoride.

Abstract:

Modern uranium enrichment facilities can simultaneously use several raw materials as feed, including natural uranium, regenerated uranium obtained as a result of SNF reprocessing, or depleted uranium (all in the form of uranium hexafluoride). As the output of the separating cascade, several types of enriched uranium product with different levels of enrichment can be fabricated simultaneously. The paper proposes a methodology, absent in literature, for calculating the cost of each enriched uranium product in multi-stream separating cascades. The proposed methodology uses standard definitions of the isotopic value of feed and product stream and the Peierls-Dirac separation potential. Numerical calculations of the cost of enriched uranium products for three production problems are provided as examples of the methodology effectiveness: 1) involvement of depleted uranium hexafluoride (DUHF) in fabrication of enriched uranium product; 2) simultaneous fabrication of two enriched products; 3) use of depleted uranium to reduce the cost of the product with a higher enrichment level out of two (as applied, e.g., to advanced tolerant fuel). It has been shown that partial additions of DUHF as feed for a multi-product separating cascade make it possible to reduce the cost of a product with a higher level of enrichment; with the current market prices for natural uranium and separative work, there is a range of tails assays in which it is more profitable to enrich DUHF rather than natural uranium.

Abstract This paper presents the results of the theoretical and computational analysis of the thermal processes during the desublimation of uranium hexafluoride and hydrogen fluoride in refrigerated containers. The technological scheme of the hydrogen fluoride desublimation in the containers refrigerated by the cold air is presented. We have substantiated the desublimation method of the uranium hexafluoride residues and hydrogen fluoride from the process stream into one container. The paper also provides the estimation of the maximum container loading, when the pressure of the saturated vapors above the surface of the desublimated mixture reaches the limiting value.

Abstract:

Intercalation of UF6 into graphite, both from the gaseous phase and from the Ledon 113 solution, was studied. The amount of intercalated UF6 from the gaseous phase was found to be inversely proportional to the size of graphite particles. Intercalation increases with the increasing temperature and surface area of graphite. The contact of gaseous UF6 with graphite led to the formation of β-UF5 that is not intercalated. In the Ledon solution, β-UF5 is not formed. "Passivation" of graphite by elementary fluorine also prevents the formation of β-UF5 but the amount of intercalated UF6 decreases. The intercalation of UF6 into graphite from the gaseous phase is accompanied by the increase of the distance between the parallel carbon atom layers up to the values of about 884 pm. Ternary intercalates graphite-UF6-Ledon 113 are formed during the intercalation of UF6 from the Ledon 113 solutions and the distance between the parallel carbon atom layers is 848-875 pm. Thermogravimetry in the presence of air revealed that the binary intercalates graphite-UF6 decompose in a 3-step reaction while the ternary intercalates decompose in a 4-step reaction. In both cases uranium hexafluoride is not released but acts as a fluorination agent on the graphite carbon.

Abstract:

In this paper, we consider the impacts of gaseous uranium hexafluoride used at concentrating plants of the nuclear industry on the human body. The appearance of uranium hexafluoride in the air of the working premises is accompanied by hydrolysis and the formation of substances that can enter the human body and bring atoms of uranium and fluorine. The article describes the method of the determination of the working conditions preventing the development of occupational diseases in employees. The method is based both on the calculation of the number of toxic substances entering the human body in routine working conditions and comparison of this number with the threshold values for different deterministic effects. The proteinuria (protein content in urine) is selected as the considered deterministic effect. We used the published statistics on the threshold of the daily release from the human body toxic substances, long-entering the body in small doses and seem to be responsible for the occurrence of urologic diseases. The calculation was performed in the framework of a complex model describing the air pollution with products of hydrolysis of uranium hexafluoride entering of toxic substances in the human body, in working premises, as well as the passing of uranium and fluorine through the body. This model constructed by the authors of this article was described in previous publications. To ensure that the theoretical methods give the same results as the experimental, the results obtained by the standard method for employees of one of the enterprises of nuclear industry were compared with the data obtained using the theoretical method under the same working conditions. The considered theoretical method can complement and enrich the existing experimental methods for the identification of the onset of occupational diseases based on the sampling of different biomaterials from the employees working at enterprises.

Abstract:

The article notes the fact that uranium hexafluoride (UHF) is the only uranium compound in a gaseous state under conditions close to normal to be used in the enrichment of natural uranium with an isotope. It is noted that during the hydrolysis of UHF in the air of a working room, this room is polluted with gases and aerosols that are carriers of uranium and fluorine atoms, which have a negative chemical and radiation effect on the human body. This, of course, poses problems when using uranium hexafluoride at the enterprises of the nuclear industry both in everyday work and, especially, in possible emergency situations. The problems lie with a need for protective measures, development of the quantitative assessment methods for the intake of toxic substances, and establishment of relationships between the amount of incorporated (ingested) substance and the measure of its effect on the body. A review of certain publications on the quantitative description of the uranium and fluorine intake in the body of employees is given. The paper notes an involvement of this article’s authors in solving this issue in their previous works too. Their calculation methods are described. The conditions under which they were carried out and the experimental results that they used were described. The article presents the calculation results both of the uranium mass intake in the body (by the time t) that characterizes the toxic effect of uranium and of the number Q of decays accumulated in the body that characterize the radiation effect. The uranium penetration through the skin (percutaneous intake) in an emergency and under normal production conditions is considered. There is given a description of two models suitable for calculations, which are distinguished by various accounting for metabolism when uranium moves from the UHF source to the exit from the human body in the natural way. It is indicated that one of the models was partially borrowed from publications of the International Commission on Radiological Protection (ICRP). The results obtained using two different models are compared and recommendations are made regarding their use depending on the tasks assigned to the researcher.

Abstract:

For a comprehensive assessment of the protection of uranium against proliferation due to the presence of uranium-232 in it, the authors of the article propose and substantiate an integral protection criterion for this material. The criterion is based on the physical barriers against the proliferation of uranium created by uranium-232, namely: (1) the radiolysis of uranium hexafluoride, which hinders attempts to re-enrich uranium and, as a result, a significant critical mass; (2) hard γ-radiation, which leads to incapacity and death of those who try to handle this material without radiation protection; (3) increased heat release, which disables the components of a nuclear explosive device; and (4) a significant source of neutrons that causes predetonation and thereby reduces the energy yield of a nuclear explosive device. These barriers appear at various stages of uranium handling not only in the indicated order but also act simultaneously, mutually reinforcing one another.

Abstract:

Abstract Reprocessed uranium gained from the spent nuclear fuel contains 232, 234, 236U isotopes within, which considerably hamper its reuse. It is proposed to use an ordinary cascade to reduce the concentration of 232, 234U. The output purified from 232, 234U is obtained in the cascade waste. The authors analysed the peculiarities of reducing concentration of 236U after the enrichment of reprocessed uranium hexafluoride in terms of 235U in the ordinary cascade and its subsequent dilution. A computational experiment was performed. Parameters of cascade stages were predetermined, which allow to reduce the content of 232, 234, 236U to an acceptable level.
