ABSTRACT:
Apparatus for severing primary tubes of steam generator of a nuclear reactor. The tubes are under water because they are radioactive and also because it is undesirable to expose the tubes to oxidation. The tubes are in a confined region of the steam generator affording limited access for cutting. The apparatus includes a file whose cutting surface is cylindrical. The file is located wholly in the region where the tube is clamped within the cooperative clamps which secure the tube for cutting. The file is rotated in cutting engagement with the tube by an air motor. The file is mounted on a slider which is pulled by a cable causing the file to cut through the tube.
