PCT No. PCT/SE89/00551 Sec. 371 Date Apr. 9, 1992 Sec. 102(e) Date Apr. 9, 1992 PCT Filed Oct. 9, 1989 PCT Pub. No. WO91/05351 PCT Pub. Date Apr. 18, 1991.An arrangement for the underwater storage of environmentally hazardous waste, particularly radioactive or chemical waste, includes at least one secondary capsule (1) in the form of a cylindrical concrete body. The concrete body has a central, axially extending storage cavity (3). The cavity has the form of a shaft which is open at one end thereof and into which a waste-containing primary capsule (2) can be inserted, whereafter the open end of the shaft or cavity is sealed. Arranged in spaced relationship around the circumference of the concrete body (1) are a number of ballast chambers (4) which can be filled with water to varying degrees and the total, combined volume of the chambers is such as to enable the concrete body to be brought to a buoyant state, by emptying the chambers. A plurality of such secondary capsules (1) enclosing waste-containing primary capsules (2) can be stored on the sea bed in an annular concrete structure (6) which is provided with a large number of circumferentially distributed and vertically extending cylindrical compartments (9) each capable of accommodating a secondary capsule (1). The annular concrete structure (6) resting on the sea bed is also provided with a large number of ballast chambers which can be filled with water to varying degrees and which have a total, combined volume such as to enable the annular concrete structure to be brought to a buoyant state by emptying the ballast chambers. |
