Migraion of radioactive nuclides from "Cover" objects

Scientific fundamentals of liquid radioactive waste products and transuranian elements purification

Abstract

Failure on the ChNPP caused a series of fundamental and applied problems. New information presented confirms the substantial role of a solid phase with the size of 0,1—1 micrometers and colloid particles (micro particles) in the mechanism of a transfer of radionuclides from the «Cover» industrial site in superficial layers of soil and in ground water. The new purification method of contaminated water wastes is offered which enables to remove an organic matter and transuraniums by oxidization with hydrogen peroxide and potassium permanganate in combination with a ultrafiltration on polymeric or inorganic membranes with the size of pore 0,05—0,10 micrometers. The developed oxidization purification is recommended for implementation on ChNPP.
