1. An apparatus for removing thermal stratification generated by turbulent penetration by using a rotation of an inner ring and an outer ring, which is apparatus for removing thermal stratification formed in a branch pipe branching from a main pipe through which a high-temperature fluid flows, the apparatus comprising:
a hollow body portion coupled to the branch pipe;
an inner ring being magnetic and arranged inside the body portion so that an inner circumferential surface thereof is in contact with a fluid; and
an outer ring arranged outside the body portion to face the inner ring, the outer ring being magnetic of a polarity opposite to a polarity of the inner ring,
wherein, when the outer ring is rotated, the inner ring rotates by a magnetic force,
wherein an insertion groove into which the inner ring is inserted is formed in an inside part of the body portion, and
a mounting groove in which the outer ring is mounted is formed in an outside part of the body portion, and
wherein magnetic materials having a same polarity as the inner ring are provided on both sides of the insertion groove facing side surfaces of the inner ring.
