Abstract

Improvements in devices for scraping the sodium deposit on a cylindrical rod movable in this metal, especially on a fuel element handling arm for a fast neutron reactor, characterized in that said devices are made up of a fixed cylindrical crown that surrounds said mobile bar, whose base is slightly frustoconical, the lower end portion of the latter constituting a knife-shaped edge that is applied to the surface of the bar with pressure, said crown being provided for this purpose with grooves arranged parallel to the axis of the reactor over most of its length.
