PULL-UP SHACKLE FOR INTEGRATED HEAD ASSEMBLY

摘要

PURPOSE: A pulling shackle of an upper structure of a reactor is provided to reduce stress focused on a specific portion and to minimize bending stress added to a connection member. CONSTITUTION: A pulling shackle(250) of an upper structure of a reactor comprises a first member(252), a second member(253), a first connection member(254), a connection unit(251), and stress reduction units(252a,253a). The first and second members are extended at constant thickness and length to be parallel to each other and respectively include upper and lower parts. The first connection member connects the upper parts of the first and second members mutually and connected to a hook. The stress reduction units are extended at constant curvature from the first connection member to lateral ends of the first and second members and protruded upwardly, thereby reducing bending stress added to the first connection member.
