A method in the storage of nuclear waste of intermediate-level radioactivity, deriving E.G. from nuclear power plants and a waste unit produced hereby.

摘要

A mixture of waste and a liquid hydraulic binder is introduced through an opening in a container, the binder is allowed to solidify, the container opening is sealed, and the container is optionally moved a repository site. The container comprises an iron material and has gas impervious walls and bottom; the seal is formed from a material or a material combination which exhibits high resistance to outward diffusion of radioactive nuclides but is permeable to gas, and in the event of the container being moved to a repository site, the container is embedded in a concrete block in the repository site. A waste unit, comprising at least one substantially cylindrical container (1) which is provided with a bottom and which accommodates a mixture (3) of intermediate-level radioactive waste deriving e.g. from a nuclear power plant, and a binder and is provided with a seal or closure means (4).
