Abstract |
|
|
| The acidity of the first cycle raffinate produced from CORAL (COmpact Reprocessing of Advanced fuels in Lead cells) is to be reduced from 4M to < 0.5M in order to reduce its volume by evaporation is achieved by electrolytic destruction of nitric acid using simulated raffinate solution. This method is developed for safe disposal of raffinate waste produced and its waste management, it is achieved using electrolytic cell containing platinum anode and titanium cathode, which in turn destroys the simulated solution of 3.85 N nitric acid containing 250 ppm of dissolved TBP is destructed to 0.7 M and 49 ppm respectively and the ~90 % of fission products and corrosion products are removed byelectro- depositionin the cathode at different temperatures with current efficiency of 67 to 80%. |
