The research deals with the purification of drain water and distillation residue from organic (polymeric) compounds, transuranic elements, and uranium. The pretreatment method with the use of Sizol type coagulant-flocculant and catalytic oxidation with hydrogen peroxide and ultrafiltration has been proposed. This method prevents the evaporator coking by dust-suppressor and other organic substances vulcanized by heating. The removal of alpha-emitting radionuclides results in the increasing safety of the nuclear power plant operation.
