An embodiment of the present invention provides a swirl vane-type moisture separator, which is provided in a reactor steam generator, separates moisture from wet steam, and supplies dry steam to a turbine side, the swirl vane-type moisture separator comprising a riser and a swirl vane. The riser includes: an inner tube which has a steam flow path formed therein, through which wet steam flows from a lower portion and dry steam is discharged to an upper portion, and a liquid film passage hole which is formed on the circumference of the upper end and through which a liquid film formed by droplets separated from the wet steam passes; and an outer tube that is provided so as to surround at least the upper circumference of the inner tube and forms a downcomer through which the liquid film that has passed through the liquid film passage hole flows down and is discharged. The swirl vane is rotatably provided at a predetermined position in the steam flow path, and separates the droplets by means of centrifugal force from the wet steam moving along the steam flow path.
