Heavy-water Reactor Pressure Tube Oxide Film Disposal Equipment And Disposal Method

The present invention relates to an apparatus for removing an oxide film on a pressure tube of a heavy-water reactor, and more particularly, to an apparatus for removing an oxide by rotating an abrasive cloth on an outer circumference of the pressure tube in order to remove the oxide which is an oxide layer accumulated around the outer circumference of the pressure tube of the heavy-water reactor. The apparatus for removing the oxide film on the pressure tube the heavy-water reactor, which removes oxide accumulated around an outer circumference of the pressure tube the heavy-water reactor in a hot cell, includes: a body (200) having a pressure tube (100) transferred to one side thereof along a horizontal direction and including a clamp (220) to which the pressure tube (100) is fixed; an abrasion unit (300) including an abrasive cloth (370) making contact with the outer circumference of the pressure tube (100) and moving along an outer surface of the pressure tube (100); and a tail stock (400) to which an opposite side of the pressure tube (100) is fixed. 본 발명은 중수로 압력관 산화막 제거장치에 관한 것으로, 중수로 압력관 외경에 적체된 산화층인 산화물을 제거하기 위하여, 상기 압력관 외경에 연마포를 회전시켜, 산화물을 제거하는 장치에 관한 것이다.
