Gamma radiolysis of EDTA in a simulated, mixed nuclear waste

  • A. P. Toste
Waste and Fuel Cycle Applications

Abstract

The effects of γ-irradiation on EDTA degradation have been studied. A simulant of Hanford's complex concentrate was prepared by adding EDTA to an inorganic matrix which was formulated based on past analyses of the actual Hanford complex concentrate waste. For, the radiolysis study, aliquots of the simulated waste were then γ-irradiated. Each waste sample was analyzed to monitor the appearance of degradation products. Based on the results of this study, an assessment of the impact of EDTA degradation on the management of mixed wastes is offered.
