<p>The present invention relates to a cooling duct assembly for control rod driving apparatus. The cooling duct assembly for control rod driving apparatus installed on an upper aggregate of a nuclear reactor includes a control rod driving apparatus disposed on the upper side of a nuclear reactor head, a cable tray disposed on the upper side of the control rod driving apparatus, and a cooling air treating apparatus disposed on the upper side of the cable tray. The present invention includes: a cylinder skirt which is combined around the nuclear rod head and a first air passage is formed therein; a lower duct in a cylinder shape which is combined with the upper side of the skirt, a second air passage connected with the first air passage is formed thereon, and is disposed to cover the control rod driving apparatus; and an upper duct which is combined with the cooling air treating apparatus and is combined to be detachable for the lower duct. Air which cools the control rod driving apparatus is discharged through the first air passage of the skirt, the second air passage of the lower duct, the upper duct, and the cooling air treating apparatus, sequentially. The upper duct separated from the lower duct is lifted with the cooling air treating apparatus.</p> |
