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.
