Electrodiffusion of Radionuclides in Lava-Like Fuel-Containing Materials

Materials Science, 2005
We pose and study the problem of transport of charged particles of radionuclides through the surface of contact of a layer of electrolyte with a lava-like fuel-containing material. It is shown that the electric charge and the strength of the electric field are concentrated in a narrow layer near the interface of layers and form the surface electric ...

Impact of open accumulations of lava-like fuel-containing materials in the CNPP shelter object on the personnel and environment

Radiochemistry, 2014
The impact of lava-like fuel-containing materials (LFCMs) of the Shelter object (SO) of the Chernobyl NPP on the environment components is evaluated. The evaluation is based on modern data on the surface area and dust-generating ability of SO LFCMs.

Processes of vertical diffusion of radionuclides in a layer of a lava-like fuel-containing material

Journal of Mathematical Sciences, 2012
Using a known model for the quantitative description of diffusion of radioactive impurities in fuel-containing materials and taking into account processes of electrolytic dissociation and electrodiffusion (in the case of charged impurities) in interrelation with thermal and electromagnetic processes, we investigate the vertical diffusion of particles ...

Long-Term Aging of Chernobyl Fuel Debris: Corium and “Lava”

Sustainability, 2021
Samples of Chernobyl fuel debris, including massive corium and “lava” were collected inside the Chernobyl “Sarcophagus” or “Shelter” in 1990, transported to Leningrad (St.

The Updated Model of Microstructure Evolution of Lava-Like Fuel-Containing Materials of 4th Block of Chornobyl NPP. Brown Ceramics

Ukrainian Journal of Physics, 2021
Модель еволюцiї мiкроструктури лавоподiбних паливовмiсних матерiалiв (ЛПВМ) 4-го блока Чорнобильської АЕС оновлено на прикладi коричневої керамiки. Пiдтверджено, що поведiнка ЛПВМ визначається не одним або декiлькома фiзичними i хiмiчними процесами, а їх взаємозв’язком i взаємовпливом.

The Distributed ROS-Based System Concept for Automation of Remote Operations with Fuel-Containing Materials at the Shelter Object

Nuclear Power and the Environment
The problem of extracting lava-like fuel-containing materials (LFCM) from the Shelter object is characterized by extreme radiation conditions (up to 103 −104 R/h) and complex facility geometry.
