The present invention relates to an alignment device of a reactor core support barrel for an internal structure of a reactor. The alignment device according to the present invention comprises: a positioning groove which is provided in the core support barrel; an alignment piece which is coupled to the positioning groove; a plumb line which is provided downward in the alignment piece; an optical target which is coupled to the upper portion of the alignment piece provided with the plumb line; and an optical measurement device which is provided at the center of the reactor support barrel. According to the present invention, the occurrence of trial and error is reduced because the existing axial line alignment references are different to prevent a defect of the axial line alignment and to minimize working time, and thus it is possible to reduce costs to obtain a working environment in which workers are minimally exposed to radiation. |
