Abstract: A lifting shackle of a head assembly for a nuclear reactor according to one embodiment of the present invention comprises: a first member and a second member which extend in parallel to each other in a predetermined thickness and length and respectively have an upper portion and a lower portion; a first connection member which connects the upper portion of the first member and the upper portion of the second member to each other and is coupled to a hook; coupling sections which are respectively provided at the lower portions of the first member and the second members and has a hollow portion so as to be coupled to the head assembly for a nuclear reactor via pins; and stress reducing sections which are formed at the upper portions of the first member and the second member such that the stress reducing sections extend from the first connection member to the first member and the side end of the second member at a predetermined curvature and protrudes upwards so as to reduce bending stress that is applied to the

Abstract: An earthquake-resistant reinforcement assembly according to one embodiment of the present invention comprises: a rod of which one end is hinge-coupled to an upper structure; a combination pin which is formed at the other end of the rod and is extended to diametrically cross the rod; and a bracket which is provided on a partition wall of a nuclear reactor containment building and is coupled with the other end, wherein the bracket can withstand a tensile load and a torsional load by including first and second members which face each other and are extended in parallel to load the rod thereon, and groove portions which are formed at the first and second members to be coupled with the combination pin to form the shape of a double bracket.
