USE OF THE MODIFIED IRON ORE RAW MATERIALS FOR RECEIVING CONSTRUCTIONAL BIOLOGICAL PROTECTION OF NUCLEAR REACTORS
Possibility of use of natural iron ore raw materials of KMA for receiving the constructional composite materials used for radiation protection of VVER NPPs reactors is shown. Mechanisms of modifying of a high-quality iron ore concentrate for the purpose of increase in technological parameters of composite mix are installed. On the basis of the modified magnetitovy concentrate, the cement knitting and kremniyorganichesky modifier (etilsilikat) the radiation protective constructional composite is received. Consistent patterns of influence of composition of raw mix and technology factors on kinetics of curing of the pressed composite material are determined. The main physics and technology characteristics of the developed composites are investigated. Pilot studies of radiation protective characteristics of the developed material on weakening of power of a dose of gamma radiation in the conditions of «barrier» geometry of protection are conducted.
