Processing and decontamination of radioactive waste with chlorinating loparite concentrate

Author: O.V. Rakhimova

Reference: Dissertation, candidate of technical sciences, Moscow, 2012

Keywords: waste processing method

Abstract: Aim of the work: To improve efficiency of processing and decontamination of radioactive waste. To complete the subject, the following are to be considered:

  1. an analysis of the formation of solid and liquid radioactive waste with chlorinating loparite  concentrates; to analyze the distribution of radionuclides on products, intermediate products and recycled waste with loparite concentrates;
  2. to select reagent-precipitator and to define the conditions, which reduce the mass of the secondary waste to be buried;
  3. to examine the conditions of decontamination as industrial solutions, and their dependence on the basic technological factors…

Physico-chemical basis of reagent decontamination of soils contaminated with α-emitters

Author: Yu.G. Sklifasovskaya

Reference: Dissertation, candidate of chemical sciences, Moscow, 2012

Keywords: solid waste, processing waste, storage

Abstract: In the Russian Federation there are still radioactively contaminated sites, and measures for their rehabilitation are included in the federal program “Nuclear Radiation Safety of Russia for the period between 2008 and 2015.” A significant portion of solid waste, annually entering specialized enterprises, constitutes of low-level soil materials removed during decontamination works. In connection with this, an important task is the development of technologies and methods for processing the incoming waste, to reduce the amount of storage (I.A. Sobolev, Vladimir Kulichenko, S. Dmitriev, etc.)…

The method of decontaminating soil from radionuclide 137cs

Author: Chirkst D.Е., Chaliyan K.N., Chaliyan A.G.

Reference: Patent, 10.12.1995 patent holder: K.N. Chaliyan

Abstract: The inventive method consists of treatment of contaminated soil with an aqueous solution, containing inorganic ammonium salt and uncomplexed inorganic iron salt, wherein the pH of the aqueous solution is 2-3. The treatment is carried out at a weight ratio of solution and soil 12,5-41,5. The degree of desorption of 137Cs after the treatment is 70-80% 1 table. …

Radionuclide Desorption Parameters from the Bottom Sediments in the Reservoir Staroye Boloto. Review of Experiments

 

Author:  Stukalov P.M., Simkina N.A.

Reference: Gazette “ВОПРОСЫ РАДИАЦИОННОЙ БЕЗОПАСНОСТИ“ (Issues on radiation safety), 2008

ISSN: 1816-9643

DOI: 621.039.7: 539.16.170 2008

Keywords: desorption parameters, resevoir, bottom sediments

Abstract: Results of experimental determination of radionuclide desorption parameters (desorption factor, washed-out activity fraction) are considered in the bottom sediments in the reservoir Staroye Boloto used as Mayak PA liquid radioactive waste storage. The principal attention is paid to the activities carried out in the Institute for Biophysics (Moscow) for dense sludge and loam beds, as well as to the Mayak PA studies (2008) ofstrontium, ceasium and uranium isotope wash-out from the upper aqueous bed of man-induced sludge oft he reservoir.

Content of Man-Caused Radionuclides in Shrubs and Mushrooms in the Area Affected by the Mining-and-Chemical Combine (the Krasnoyarskii Krai) (probably available in English)

 

Author: Dementyev Dmitry V., Bolsunovsky Alexander Ya.

Reference: Journal of Siberian Federal University

ISSN: 1997-1389          

DOI: 579.5:539.752+577(T2-575):582.16

Keywords: radionuclides; transfer factor; mushrooms; shrubs

Abstract: The study addresses accumulation of radionuclides by mushrooms and berry shrubs from the forest soil in the area around the Mining-and-Chemical Combine (the Krasnoyarskii Krai, Russia). The Suillus granulatus and S. luteus mushrooms have been found to be the best bioindicators in this area. The level of 137Cs concentration in these species can reach 10 kBq/kg dry mass. The 137Cs transfer factor (TF) by the mushrooms varies 5-fold among the sites that receive radionuclides from different sources. The level of radionuclide activities accumulated by berry shrubs is 2-3 orders of magnitude lower than the activities accumulated by mushrooms. Based on the calculated TFs, the distribution of 137Cs and 60Co among the parts of these shrubs is as follows: branches
