Study of Radiation Resistance of Polymer Compound with Included Spent Ion-Exchange Resins
A technology and installation for conditioning of spent ion-exchange resins by dehydration and inclusion in a polymer binder have been developed. Radiation resistance of the polymer compound obtained has been assessed in accordance with regulatory requirements using developed and certified methods. Mechanical strength (compressive strength) has been adopted as an indicator characterizing the structure of the polymer compound. It has been found that, at a radiation dose of 104 Gy, the strength of the composition under study increases, and this is due to the radiation crosslinking phenomenon, which leads to the formation of additional chemical bonds and strengthening of the matrix. The volume of polymer compound samples when irradiated with doses of 104–106 Gy decreases, which guarantees the integrity of containers used for its storage/burial. The rate of radionuclide leaching from polymer compound samples during irradiation also decreases and is within the requirements of NP-019-15. The compliance of the polymer compound with the normative requirements of radiation resistance in terms of invariability of its structure and water resistance is shown.
期刊介绍:
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
