Different concrete compositions as a reactor shielding material for neutrons and gamma rays
Original language description
In a reactor during the fission or fusion reaction the prime radiation produced are neutrons and photons [1]. The shielding design of a reactor or any radiation facility is a crucial part. The selection of a shielding material is based on its efficiency to shield the radiation and effective in cost. The major shielding materials for neutrons are HDPE, B4C, concrete, etc. Whereas gamma rays can be shielded with Pb, W, U2O, etc.[2]. The concrete is used as a common shielding material as it is very cost effective and has long durability [3]. The ordinary and reactor grade concrete provides shielding to both neutrons and gammas. For high neutron flux the thickness of the concrete required must be large. Hence, this will increase the cost and the occupied space. In present paper we have tried to introduce some materials in concrete composition to get more effective shielding. The materials are added in such a way that the overall density of the concrete doesn’t change but the effect in reduction of the neu
