PCT No. PCT/SE82/00202 Sec. 371 Date Feb. 8, 1984 Sec. 102(e) Date Feb. 8, 1984 PCT Filed Jun. 9, 1982 PCT Pub. No. WO83/04455 PCT Pub. Date Dec. 22, 1983.The invention provides for a procedure for permanently storing radioactive material in a rock chamber, comprising an enclosed construction (4) completely separated from the walls, floor and ceiling of the rock, made of permanent material impervious to water, in which materials in encapsulated (9) form are stored, and the outer spacing between the walls, ceiling and floor of the rock and the construction is completely filled with material not impervious to water (5). In the invention, the encapsulated material is placed inside the construction by means of a robot (10) on both sides of a track provided for the robot. When the construction is totally or partially filled with material, the construction or part of it containing material is sealed with bentonite or similar, leaving a passage (13) for the robot in the construction, which passage is filled with water-displacing material that is easy to dig. When the construction is completely filled, it is sealed up and the robot (10) is lifted up through a lift-shaft (3) connecting the construction with ground-level. The lift-shaft is sealed at least at the level of the construction and at ground-level.
