<p>The present invention relates to a support for vibration damping in a nuclear fuel assembly by a manual vibration damping manner, capable of effectively insulating the vibration in the external horizontal direction, characterized by comprising a lower frame (110) which is formed as a square shaped frame and has a vertical beam (112) which is formed to be vertically extended at each corner; a horizontal operation unit (120) which is mounted in the upper part of the vertical beam and is arranged to be moved in the orthogonal direction to the horizontal plane; an upper frame (130) which is located in the horizontal operation unit (120) as a square shaped frame and has an elastic member (131) arranged in the vertical direction to be oriented to the lower frame (110) at the four sides; a fixation plate (140) which is fixed to the elastic member; and a flexible beam (151, 152) in which both ends are horizontally connected to the fixation plate (140) and the vertical beam (112) of the lower frame (110), thereby preventing a fuel rod from being damaged by effectively damping the vibration in the horizontal direction that may be generated in the nuclear fuel assembly by a manual vibration damping means consisting of only flexible beams without affecting the flow of cooling water supplied to a nuclear reactor.</p> |
