Nut sheath for the wall screws of vessels subject to nuclear irradiations
Description
This invention relates to a tube designed to be sealed into the wall of a vessel subject to nuclear irradiations. It enables the easy assembling and dismantling of anti-nuclear irradiation ventilation screws while assuring at the same time an absolute impermeability to the passage of these irradiations, in spite of a relatively large amount of play between the screw and sheath
