METHOD OF THE RADIOACTIVE WASTE DISPOSAL Russian patent published in 2005 - IPC

FIELD: methods of the radioactive waste disposal.

SUBSTANCE: the invention is pertaining to the field of the radioactive waste disposal. Substance of the invention: the method of the radioactive waste disposal includes boring of a borehole, placement of containers with the A-waste and leaving of a barrier pillar in the zone of the plastic deformations of the surrounding rocks, filling of the free volume of the borehole with an expanding plugging material and sealing of a the borehole head. At that the A-waste disposal is conducted in a clay bed, which is in a plastic state. The containers with the A-waste are placed in the middle part of the clay bed in its section with a length of l = m -_{2hδ, where "m" is the clay bed thickness, hδ is the thickness of argillaceous rocks. The plugging of the free volume of the borehole is conducted using the extracted from the borehole dried and crushed rock. At that on the section of placement of the containers the plugging is performed by substitution of the drilling mud, and on the section of the barrier pillar after an evacuation of the drilling mud - by portioned feed with water addition in the volume corresponding to the natural humidity. Advantages of the invention consist in an increased degree of reliability at the radioactive waste land disposal.}

EFFECT: the invention ensures an increased degree of reliability at the radioactive waste land disposal.
