Claim:
1. An earthquake-resistant reinforcement assembly formed to support the longitudinal and transverse directional behavior of a nuclear reactor upper structure when an earthquake occurs, comprising: a rod an end of which is hinge-coupled to the upper structure; a coupling pin formed at the other end of the rod, and extended to diametrically cross the rod; and a bracket installed at a partition wall of a nuclear reactor containment building, and coupled to the other end thereof, wherein the bracket comprises: wherein lateral surfaces constituting each of the groove portions are formed to be inclined at a predetermined angle toward the upper structure from a vertical surface thereof, wherein inclinations of at least one of the lateral surfaces for each of the groove portions begin at openings of the groove portions, and wherein the groove portions are formed so that cross-sectional areas of the groove portions increase as the groove portions extend away from the openings so as to increase an area in contact with the coupling pin in an axial direction of the coupling pin.
