Trapping of Nitrogen Oxides in Radiochemical Technologies

Abstract

A scheme for trapping the nitrogen oxides released during operations with liquids in radiochemical technologies is develop-ed: the outgoing gases containing nitrogen oxides pass through a dephlegmator (in the process of dissolution of fuel or wastes) or bubbler condenser (in the process of denitration and vitrification), through FSGO and FARTOS filters after water aerosols are introduced into them, and through the RFTBL and then SMOG apparatus after the next water-aerosol portion is introduced. The proposed solution is incorporated in the technological schemes of the spent nuclear fuel reprocessing module in the on-site nuclear fuel cycle of the BREST reactor.
