Abstract: COmpact Reprocessing facility for Advanced Fuels in Lead shielded cell (CORAL) is facility in India to reprocess spent fast reactor fuels. Waste streams from a reprocessing facility must be characterized using reliable analytical methods to support effective waste management and enable potential resource recovery. This study examines 99Tc distribution in waste streams of the CORAL by Tetraphenyl arsonium chloride (TPAC)–Chloroform extraction method. 99Tc was analysed using gross beta counting using Geiger–Müller (G–M) counter and Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES). The result of this study indicates that ICP-OES offering superior accuracy as compared to beta counting method. Mass balance studies showed ~ 92% of 99Tc is in raffinate, ~ 1.5% in products, 1.5% in ADU filtrate, and ≤ 5% in lean organic. These results will provide valuable inputs to waste managers for optimizing waste-management strategies for high and low activity wastes containing 99Tc generated during fast-reactor fuel reprocessing.
