Hot-pressed boron carbide (B_4C) pellet will be used as shielding material in China Experimental Fast Reactor (CEFR) which is the first fast reactor in China. In this paper, two types of B_4C sample provided by two different units in China were investigated on out-reactor properties, and one type of sample was studied on irradiation performance. Finally, the approval of domestic B_4C pellet as shielding material in CEFR was given.
