Abstract
The present invention relates to a structure for storing radioactive material in rock, having a body (4) for accommodating radioactive material, the body (4) being encompassed by rock around which a cavity (3) may optionally be formed, there being arranged in the cavity a barrier (5) comprising a water-swelling elastoplastic material. The body (4) includes a substantially vertical central shaft (8), a vertical shaft (10) of annular cross-section and extending concentrically with the central shaft (8), and a plurality of vertical drifts (12) located at a distance from the center axis of the central shaft (8). The body also has arranged therein a plurality of vertically located strata for storing radioactive material, each stratum comprising a plurality of tubular adits (9) which extend radially from the center axis of the central shaft (8) and the longitudinal axes of which form an acute angle with the center axis of the central shaft (8), the shaft (10) and the vertical drifts (12) being connected together in the proximity of the upper and lower parts of the central shaft.
