The stages of multiyear investigations of the fuel-containing materials remaining in the Shelter after the accident at the Chernobyl nuclear power plant, including the determination of their total amount and the physicochemical properties, are described. Thus far ∼150 tons of fuel from the destroyed reactor have been found inside the Shelter. Another ∼ 30 tons could be located in sites which are still inaccessible to investigators. One section of this paper is devoted to the analysis of the… 
Transuranium elements in liquid radioactive wastes from the Shelter
The volume activity of 90Sr, 137Cs, 238Pu, 239+240Pu, 241Am, and 244Cm in water taken from unorganized water accumulations on lower marks of the Shelter was determined. Separate water accumulations
The model of microstructure evolution of lava-like fuel-containing materials (LFCM) in Unit 4 of the Chornobyl NPP has been updated by an example of brown ceramics. It was confirmed that the behavior
137Cs activity concentration in the ground-level air in the Ignalina NPP region
Results of the Cs activity concentration measurements in the ground-level air in the Ignalina Nuclear Power Plant (Ignalina NPP) region in 1978–2006 are presented and discussed. The peculiarities of
Synthesis of simulant ‘lava-like’ fuel containing materials (LFCM) from the Chernobyl reactor Unit 4 meltdown
A preliminary investigation of the synthesis and characterization of simulant ‘lava-like’ fuel containing materials (LFCM), as low activity analogues of LFCM produced by the melt down of Chernobyl
Origin of a signal detected with the LSD detector after the accident at the chernobyl nuclear power plant
A rare signal was detected at 23:53 Moscow time on April 27, 1986 with the LSD low-background scintillation detector located under Mont Blanc at a distance of 1820 km from Chernobyl. To reveal the
Оновлена модель еволюції мікроструктури лавоподіб-них паливовмісних матеріалів 4-го блока ЧАЕС. Коричнева кераміка
Модель еволюцiї мiкроструктури лавоподiбних паливовмiсних матерiалiв (ЛПВМ) 4-го блока Чорнобильської АЕС оновлено на прикладi коричневої керамiки. Пiдтверджено, що поведiнка ЛПВМ визначається не
Method of X-Ray Diffraction Data Processing for Multiphase Materials with Low Phase Contents
Amorphous, glass, and glass-ceramic materials practically always include a significant number (more than eight) of crystalline phases, with the contents of the latter ranging from a few wt.% to


Emission of Radionuclides from the Destroyed Unit of the Chernobyl Nuclear Power Plant
Investigations of radionuclide emission resulting from the Chernobyl accident are briefly reviewed. Three ways to estimate emission are examined: direct investigations of radionuclides emitted from
Sputtering is a well-known phenomenon, which has been under investigation for the last decades in both the theoretical and experimental ways [1,2] for numerous substances. As usually, one can
Handling Irradiated RBMK-1000 and VVÉR-1000 Fuel during the Growth of Nuclear Power
On-site storage facilities, consisting of ponds with water, for irradiated RBMK-1000 fuel are now close to being filled. To continue operating nuclear power plants with RBMK reactors, it is necessary
