NUCLEAR FUEL SINTERED BODY HAVING EXCELLENT IMPACT RESISTANCE
The present invention relates to a sintered body in a cylindrical shape manufactured by UO2 powder, the sintered body consisting of a dish (10) having both ends of a cylindrical shape formed by spherical grooves, wherein the centers of the both end surfaces have a constant curved surface; a shoulder (20) circularly formed along the rim of the dish (10) having a constant width, which is perpendicular to the cylindrical shape; and a chamfer (30) formed as a chamfered edge along the rim of the shoulder (20). Provided is a nuclear fuel sintered body having excellent impact resistance, wherein the width (SW) of the shoulder (20) is 0.20 mm to 0.80 mm and the angle between the chamfer (30) and the horizontal plane is 14° to 18°, thereby enhancing the impact strength of the sintered body as the shape of the sintered body is improved, so as to minimize the Pellet-Clad Mechanical Interaction (PCMI) damage by means of a missing pellet surface (MPS).
