Project summary

In all the nuclear and nuclear powered object possessing countries the significant quantities of the liquid radioactive waste (LRW) with different radioactivity are accumulated and being generated. Currently the issue in question governs in many aspects the future of the nuclear power industry.

All the existing LRW processing schemes are based on the following three methods:

– precipitation technology;

– sorption technology;
– desalination technology (electrodialysis, reverse osmosis, evaporation).

Many technological layouts use a combination of the above, however, the sorption technology is the basic LRW decontamination technique in the majority of cases.

Application of the non-selective organic ion exchange media in the sorption processes gives rise to the formation of vast volume of the secondary waste arising in the mandatory regeneration processes. Currently many studies are aimed at the creation of the selective disposable and multi-cycle sorbents with high capacity and good kinetic characteristics.

The goal of the proposed project is to create and study a number of sorbents intended for the efficient removal from the solutions of the major long-lived radionuclides from Cs and Sr to Am and Cm and some toxic heavy metals.

Sorbent synthesis is based of the following main principles:

– low cost;

– improved kinetics;
– high capacity with respect to the target component.

To achieve the goal, we suppose to use for the carriers various organic matrices and the activated non-woven materials of both the organic and inorganic origin with the specific surface area below 1,000 m2/g. For the functional groups the sorbents contain complex transition metal ions, polyvalent ion salts, and stereo specific aminocarboxylic and aminophosphonic compounds.

Optimum sorbent synthesis conditions will be searched by means of the mathematic experimental design. Using the theoretical models already developed one has the possibility to forecast the capacity of the sorbents to be synthesized and the solution flow rates as well.

Determination of the sorbent properties will be performed by means of the extensive physicochemical studies, bench scale tests of the sorbents, and by the demonstration of the technology with actual LRW arisen at different radiochemical enterprises.

The project is going to be implemented by the high skilled specialists from the Federal State Unitarian Enterprise A.A. Bochvar All-Russia Research Institute of Inorganic Materials, M.V. Lomonosov Moscow State University (MSU), Institute of Physical Chemistry of the Russian Academy of Sciences (IPC RAS), State Unitary Enterprise Scientific and Production Association “Radon” of Moscow (SUE SPA “Radon”). Principal Investigator of the project is Yury A. Zolotov, academician of RAS, Doctor of Chemical Sciences.

Role of Foreign Collaborators.

The following is assumed to be carried on: sharing the information on Project implementation; joint discussions in the scientific and technical workshops and working group meetings; joint participation in the international conferences and symposia on the issues of the radioactive waste management.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
