    Abstract: Disclosed is a method for containing high-level radioactive waste in a body resistant to leaching by water. The method includes the steps of providing a mass containing radioactive substances and either a material which is resistant to leaching by water or a material which when heated forms a material resistant to leaching by water, enclosing the mass in a capsule, and then isostatically pressing the capsule at a temperature and pressure sufficient to form a coherent, dense body from the mass.

    Abstract: In the hydrostatic extrusion of tubes in a press which has a pressure chamber containing a high pressure cylinder, a pressure generating portion insertable into the cylinder, a die arranged in the cylinder and a mandrel axially fixed in relation to the die and composed of a carrier portion and a tip, and in which the tip forms with the opening in the die a gap in which a tubular billet is shaped into a tube by hydrostatic extrusion, in connection with the insertion of the tubular billet, a seal is produced initially between the mandrel and the hole in the billet at a point between the front part of the mandrel carrier and the hollow wall of the billet. This may be done by producing a constriction of the front end of the hole in the billet before the mandrel is inserted therein or by upsetting the billet against the die.

    Abstract: For detecting leakage past a high pressure seal which seals a space in which a high pressure exists, there is arranged outside the high pressure seal a collection space for pressure medium which leaks into the space and a device is provided connected with the space to detect changes in the pressure or temperature therein and to produce a signal or to stop the press. The detecting device may be an insulated cable which seals the space on the side remote from the high pressure seal and which may be broken by pressure within the space, thereby interrupting an electrical circuit.
