Project summary

Development of modern nuclear power engineering and the growth of nuclear wastes engender more and more strict requirements to be met by material scientists and engineers in working out materials with high absorbing (against neutron and other irradiation) and physical-mechanical properties.

The use of high-molecular compounds (HMC) as a base material characterized by the high radiation resistance and the addition of a boron-based component make possible to develop elastic composite materials HMC-B with high absorbing properties.

The elasticity of materials is provided by the presence of HMC in the composition and effective absorbing properties-by the additional boron component.

The applications of modern technology make possible the fabrication of films made from above compositions within the wide range of their components and with effective absorbing properties. The goal of the proposed Project is the development of new hard and elastic composite materials HMC-B in the form of plates and films with high absorbing and physical-mechanical properties. The guarantee for the successful fulfillment of this goal is based upon the existent experience of weapon scientists active in the field and, that is of high importance, on results of research experiments on the base of which the given proposal was prepared.

The role of foreign collaborators consists of joint investigations and discussions of obtained results, reciprocal visits and preparation of joint publications.

The existing background allows creating highly effective specific guard shields for protection of biological objects against the radiation and for insulating radiation sources.

The conducted investigations will result in drawing up technical documentation – publications, report and regulations for producing radiation resistant polymeric compositions, technology for their treatment and obtaining of hard and elastic radiation – resistant shields.
