Abstract: An anti-seismic apparatus for control element drive mechanisms of a nuclear reactor includes: an anti-seismic support plate including a plurality of insertion holes in which the control element drive mechanisms are respectively inserted; and bushings inserted between outer surfaces of the control element drive mechanisms and inner surfaces of the insertion holes. The support plate includes an upper support plate comprising a plurality of first insertion holes, a lower support plate comprising a plurality of second insertion holes at positions corresponding to the first insertion holes, and a connection part connecting the upper support plate and the lower support plate. The connection part includes a support beam vertically extending from an end portion of the lower support plate, an inner flange extending inward from an upper end portion of the support beam, and an outer flange extending outward from the upper end portion of the support beam.

Abstract: The cooling duct assembly for a control element drive mechanism (CEDM) includes a skirt that is combined on a circumference of a reactor head and has first air channels in an inner side thereof; a lower duct that is combined with an upper side of the skirt, has second air channels that are connected to the first air channels, and is disposed to surround a circumference of the CEDM; and an upper duct, an edge of which is combined with the cooling air handling device, and other edge of which is detachably combined with the lower duct, wherein air that cools the CEDM is discharged to the outside after sequentially passing the first air channels, the second air channels, the upper duct, and the cooling air handling device, and the upper duct separated from the lower duct is lifted together with the cooling air handling device.
