Abstract: A method of containing radioactive or other dangerous material separately or intermixed with a bonding compound of a material, resistant to leaching by water, in a gas-tight container and of converting the material by hot isostatic pressing (HIP) into a dense body. The material is filled into a cylindrical container having a corrugated bellows-like wall. The dangerous material is prevented from filling up the annular spaces formed by the corrugations, by means of a barrier means placed inside the container. A metallic netting combined with a paper-like sheet of ceramic material makes a suitable barrier means.

Abstract: Spent fuel rods from a nuclear reactor are enclosed in a body of copper, the fuel rods being embedded in copper powder in a copper container provided with a copper lid. The container with its contents and lid are then subjected to isostatic compression at a pressure and temperature sufficient to form a coherent dense mass unit of the powder, the container and the lid which embeds the fuel rods. The container can be enclosed in a sealed gas-tight capsule prior to the isostatic compression. A preliminary isostatic compression may be conducted at a lower temperature to effect creep deformation of the container, the lid and the powder.

Abstract: A container for enclosing particulate or piece-formed radioactive material which is to be converted into a solid body by isostatic pressing at a high temperature and a high pressure. The container may have a corrugated sheath and suitably a plane lid and a plane bottom. The corrugation makes possible axial compression of the container prior to the pressing. The container may also have a cylindrical sheath and bellows projecting into the sheath and joining the sheath of the container to a lid and a bottom. The bellows make it possible to insert the lid and the bottom by gas pressure, so that the material present in the container is axially compressed.
