Abstract
The present invention relates to a storage plant for storing radioactive material in rock formations, the plant comprising a cavity (4) for accommodating radioactive material, the cavity (4) having therearound a rock shield (6) in which a further cavity (7) is optionally formed, there being arranged in the optional cavity a barrier (8) comprising a resilient material which swells in water. Arranged around the second cavity (7) and spaced therefrom is a helical tunnel (12). Entry tunnels (13) extend from the helical tunnel (12), in towards the remaining parts (4,7) of the plant. The invention is characterized in that at least one cage of substantially vertical drill holes (14) is arranged around the plant, preferably in connection with the helical tunnel (12), for taking-up and conducting away water arriving at and departing from the inner part of the storage plant.
