Research of Processes Sedimentation Sludge Radioactive Waters and the Improvement of Treatment Technology

It can be literally said that further development of nuclear-power engineering will be finally determined by a possibility of safe treatment of radioactive wastes with prevention of their contact with the biosphere. Isolation and prevention of environment radioactive contamination determined a necessity of concentration and solidification of radionuclide, which could be disposed over a long period of time. One of the main and necessary conditions for creating stable and safe radioactive wastes is maximal moisture removal with a maximal degree of their concentration in the binder [1]. The experience of operating existing systems of preliminary radioactive water purification at Nuclear Power Plant showed that one of the important and unsolved problems is improving the efficiency of removal of dispersed admixture from radioactive water. Low rate of suspension removal of the existing technology leads to sludge getting into radioactive wastes that makes the operation of the vaporizer difficult, to setting of deep concentration by evaporation, and, what is also very important, it leads to increase in quantity of liquid radioactive wastes.
