Joint Institute of Power and Nuclear Research - Sosny offers consumers technology for the production of polymer decontamination coatings for “dry” decontamination and protective polymer compositions under a commercial proposal with technical assistance and looking for partners for the development of the technology under a technical cooperation agreement.

The action of coatings for "dry" decontamination consists in the penetration of radionuclides into the film or paste material and the removal of the hardened coating together with the radioactive contaminants retained in it. These methods can be used to remove fixed and/or loose contaminants without damaging the substrate surface. Without aggressive components in the composition and in the presence of inhibitors, the films can serve as a coating for protecting metal and concrete surfaces used in aggressive environments from corrosion. Developed at the scientific institution "JIPNR - Sosny" polymer compositions are competitive and are not inferior in properties to decontaminating film-forming compositions from other manufacturers. Research work has been carried out, technical conditions and formulations for decontaminating compositions have been developed and registered in accordance with the established procedure.

The compositions are promising for use in nuclear power engineering, the atomic industry, the production of radioisotope products, in organizations using open sources of ionizing radiation. The creation of decontamination compositions based on polymer films (pastes) is a priority area for environmentally friendly low-waste decontamination technologies, and can also play a positive role in achieving safe long-term storage / disposal of radioactive waste against the background of new environmental standards and the growing role of nuclear energy. The use of the developed polymer coatings at nuclear power plants and in organizations using open sources of ionizing radiation is promising.

In accordance with modern economic development trends, there is a need to develop and organize the production of domestic materials capable of replacing similar imported products.

The economic significance of the development lies in import substitution, increasing the efficiency of decontamination, improving the economic indicators of the decontamination process by reducing the costs of processing decontamination waste, introducing decontamination technologies that ensure a reduction in the volume of operational radioactive waste (RW) by 10 times or more, it is possible to obtain an economic effect due to a reduction in the costs of final isolation of RW, and also to reduce the collective effective dose received by personnel.

The production of decontamination compositions based on polymer films is environmentally safe, since it eliminates the presence of wastewater containing toxic components.

The use of film-forming coatings for decontamination of equipment allows:
- reduce radiation doses for personnel by reducing the time the personnel spends near the decontaminated equipment;
- reduce downtime and significantly save money on decontamination carried out at various stages of operation and decommissioning of nuclear installations;
- reduce the environmental hazard of the decontamination process by reducing the amount of solid radioactive waste and eliminating the formation of liquid radioactive waste;
- ensure safe long-term storage / disposal of radioactive waste against the background of new environmental standards and the growing role of nuclear energy.

Improvement of decontamination technologies and the use of domestic protective coatings that are characterized by high decontamination capacity and resistance to aggressive environments.

Joint Institute of Power and Nuclear Research - Sosny (Institute of Nuclear Power Engineering of the Academy of Sciences of the BSSR) was one of the largest scientific centers of the USSR on nuclear power. The Institute is defined as an organization performing scientific support for the construction and operation of nuclear power plants.

From the first days of the Chernobyl accident, the Institute was involved in solving such important problems as determining the levels of radioactive contamination of the territory of the Republic with radioactive isotopes and the levels of irradiation of the population of the affected regions, monitoring the radioactive contamination of food products produced in the Republic, which became an important factor in choosing the strategy and tactics of measures to protect the population from radiation hazard.

The main areas of activity of the Institute:
- nuclear energy, scientific support for the development of nuclear energy in the Republic of Belarus;
- nuclear and radiation technologies in the interests of various sectors of the economy of the Republic of Belarus;
- handling radioactive waste and spent nuclear fuel;
- fundamental and applied research in the field of nuclear physics, particle physics, high energy physics.

Promising areas of the Institute's activities:
- development of methods for modeling neutron-physical and thermal-hydraulic processes and their application in substantiating the safety of the Belarusian NPP;
- computational, theoretical and experimental substantiation of thermal-hydraulic and neutron-physical characteristics of power and research nuclear reactors;
- development of methods for probabilistic safety analysis of nuclear facilities;
- fundamental and applied research in the physics and kinetics of subcritical systems based on the synthesis of fission and fission reactions (Accelerator Driven Systems) and long-lived waste incineration technologies (Accelerator Driven Transmution Technologies);
- development of technologies based on particle and radiation sources for the production of micro-, nano- and optoelectronics, precision surface treatment of materials, radiation testing and modification of polymer products, production of medicines and drugs, sterilization of medical products, etc. (NG-12-1, UELV-10-10, UGU-420, "Giatsint" stand), development of high technologies using ionizing radiation;
- development of supercomputer and Grid technologies and their application in nuclear physics and power engineering;
- development of precision non-destructive testing methods and expert testing of radioactive materials;
- development of a methodology for monitoring energy security and measures to reduce the likelihood of threats to energy security and ensure the operation of the republic's fuel and energy complex in emergency situations;
- research and optimization of the efficient use of renewable energy sources (biomass, solar and wind energy);
- development of methods for assessing environmental and economic consequences and decision-making in emergency situations during radiation and nuclear accidents;
- development of a technology for the production of a new generation of radiopharmaceuticals for the treatment of oncological diseases;
- development of technologies and measures to eliminate temporary burial sites for radioactive waste in places of former deployment of USSR troops and to prevent negative consequences of the impact of radioactive waste storage facilities outside Belarus.

The Institute carries out a great deal of work on the implementation by the Republic of Belarus of the Treaty on the Non-Proliferation of Nuclear Weapons, the Convention on the Physical Protection of Nuclear Materials and the IAEA Safeguards Agreement on the Non-Diversion of Nuclear Materials from Peaceful to Military Activities.
