Processes to decontaminate alpha, beta and gamma bearing wastes by leaching were studied in the laboratory and at pilot scale. The objectives were: (i) to decontaminate solid or liquid wastes to values within the acceptable limit for surface disposal (residual alpha contamination of below 0.1 Ci per tonne of infill); (ii) to recover leached alpha emitters (Pu, Am, Cm) for separate management of fission products (recycling, transmutation and storage); (iii) to manage fission product effluents and corrosion products resulting from these treatments; (iv) to recycle the electrochemical mediators used. The laboratory studies pursued two main aims: further basic research into the reduction method, begun under the previous contract no. FI1W-0013, and development of applications of the oxidation method to the Ag(II) electrically generated on some of the waste downstreams of the fuel cycle. This report is a synthesis of the main results obtained.
