ENVIRONMENTAL PROPERTIES ON CONCRETE WALLS SHIELDING FOR PREVENTION OF BIOLOGICAL PENETRATION HARM RADIATION IN REACTOR VVER-1000

Concrete walls as a general material being used in constructions can shield radiation transfer making environmentally safe health condition area for human and lives. Certainly, geometry of structures and properties of the used concrete affect the shielding ability against the different intensities of radiation sources. This research, has analyzed exploration for wide range of category of concrete, used at the present time for biological harm shielding of nuclear power plant VVER-1000 for the purpose of choice of the most effective amongst them. Analyses and results in this search have performed with the help of engineering programs. These programs developed in the faculty Construction nuclear installation . With the engineering program it has been analyzed the total activation of concrete for the different time of radiation and persistence, thickness of radioactive layer biological shielding and volume radioactive waste depending on the time inducing after discontinuation operation of reactor.
