Development of nuclear power reactor shielding using two different types of heavy concrete

Abstract EN

Nuclear power stations and nuclear research reactors use concrete of different types for building biological shields.

Different types of aggregates are used to form concrete of different properties to achieve radiation safety.

This paper is concerned with the study of the mathematical modeling of nuclear power reactor using Mont Carlo code to calculate the neutron and gamma ray flux and dose rate distribution at different distances in biological shield of a nuclear power reactor using two types of heavy weight concrete.

These are made from local magnetite ores mixed with steel punching and basalt ore.

The Steel- Magnetite Concrete has a density ∫ = 5.11 g/cm3 and the Magnetite- Basalt Concrete has a density ∫ = 3.05 g/cm3.

The results of calculation of neutron and gamma ray fluxes and dose rate distribution through these concretes were displayed in the form tabulated data and fluxes and dose rates attenuation curves.

The obtained results are compared with their counterpart calculated for ordinary concrete of ∫ = 2.3 g/cm3.

According to the obtained data, heavy weight concretes made from steel magnetite can be used for a proper design of biological shields for nuclear power plants and their associated facilities.
