Abstract

Liquid as well as solid organic radioactive waste can be processed by means of combustion. However, this method presents several well-known drawbacks including the corrosion of the ovens, the production of radioactive ashes and radioactive or toxic volatile products. The electrochemical mediation process is an excellent alternative to combustion, especially when dealing with hazardous materials such as explosives, pesticides, drugs and nuclear organic waste. Nevertheless, using the silver(II) species as electrogenerated mediator, requires to work in concentrated nitric acid media, which results, via its electrolysis, in a continuous NO_x emission. The classical approach, using absorption columns and scrubbers to trap NO_x, impairs the attractiveness of this process. Therefore the SCK•CBN has developed and patented an original method to suppress in-situ any formation of NO _x, conferring the process mobility and compactness.
