METHOD OF FIXING PULP IN OPEN RADIOACTIVE WASTE STORAGE POND Russian patent published in 2014 - IPC G21F9/20 

FIELD: physics, atomic power.

SUBSTANCE: invention relates to atomic power engineering and methods of handling radioactive wastes, particularly methods of fixing pulp in open radioactive waste storage ponds by filling with soil. The method involves dividing the pond with separating dikes which reach the bottom of the pond into regions, dividing the regions between the separating dikes with additional transverse dikes into cells which are filled with soil. A transverse dike is built by pouring soil on ice until the ice sags by a depth which provides a gap between the dike and the bottom of the pond through which the cell is linked through the decantate with the unfilled part of the pond. The decantate is forced under the ice from the cell into the water area of the pond through the gap between the transverse dike and the bottom of the pond by pouring part of the soil intended for filling the cell onto the ice of the cell until the ice sags. After forcing the decantate out of the cell, the cell is insulated from the water area of the pond by building a transverse dike until sagging thereof to the bottom of the pond and the insulated cell is filled with the remaining soil, and the decantate forced out during filling is pumped out.

EFFECT: improved method.
