Properties of concrete/boron carbide as neutron shielding materials
Abstract
Abstract
Cement and concrete has been widely used as shielding material in reactor nuclear in order to minimize exposure to individuals. In this paper we present boron based concrete as neutron shielding for nuclear reactor applications. Concrete specimens with dimension of 10x10x10 cm were used and irradiated with neutron radiation of 252-californium. Characterization of physical, mechanical and radiation attenuation properties of concrete were carried out. The results show that the shielding performance is better than ordinary concrete. From the result, we confirmed that the performance of the concrete/boron carbide is suitable for practical use.
Abstrak
Menyatukan dan konkrit telah digunakan dengan meluas kerana bahan adang dalam reaktor nuklear supaya meminimumkan pendedahan kepada individu. Dalam kertas ini kami hadir boron berpangkalan konkrit apabila neutron melindungi untuk permohonan-permohonan reaktor nuklear. Spesimen-spesimen konkrit dengan dimensi 10x10x10 cm telah digunakan dan disoroti dengan sinaran neutron 252 kalifornium. Pencirian fizikal, mekanikal dan ciri-ciri pengecilan sinaran konkrit dijalankan. Keputusan-keputusan menunjukkan yang prestasi yang melindungi lebih baik daripada konkrit biasa. Dari hasil, kami mengesahkan yang prestasi konkrit / karbida boron ada sesuai untuk kegunaan praktis.
