Abstract: A cladding tube coating apparatus includes a chamber unit configured to create a zirconium alloy coating environment using arc ion plating, a rotating support portion provided in the chamber unit to accommodate a plurality of cladding tubes, which are coating objects, and a target portion provided in the chamber unit toward the plurality of cladding tubes accommodated in the rotation support portion and ionized as an oxidation-resistant material is melted and evaporated due to an arcing phenomenon, wherein the rotation support portion includes a plurality of rotary tables on which the plurality of cladding tubes are rotationally supported, supports the rotary tables so that a rotation speed of the plurality of cladding tubes is constant at a preset speed, and supports the rotary table to maintain a coating thickness uniformly in longitudinal and circumferential directions.
