The chemistry of the noble metal fission product, ruthenium is very complex due to the existence of many oxidation states in addition to forming a large number of co-ordination complexes. In the PUREX process for the separation of U and Pu from the spent nuclear fuels from fast breeder reactors, owing to the high volatile nature of RuO4 problems arise not only during the extraction stages but also in the treatment of high active liquid waste and subsequent vitrification. As this volatile RuO4…

Feasibility studies on the separation of ruthenium from high level liquid waste by constant potential electro-oxidation
Abstract Ruthenium is one of the most abundant fission products in fast breeder reactors. It creates problems during the reprocessing of spent fuel and in the management and disposal of wastes, owing
Understanding the recovery of Ruthenium from acidic feeds by oxidative solvent extraction studies
Abstract Ruthenium (106Ru), a notorious fission product in nuclear reprocessing cycle, which gets partitioned at each step needs to be recovered. The recovery of Ru from acidic high level waste (HLW)
An efficient method for radio-ruthenium separation from acidic feeds: Extraction, transport and spectroscopic studies
Abstract Ruthenium is a troublesome product in spent fuel reprocessing/waste management plants. Its recovery from high level waste (HLW) is challenging due to variable speciation of Ruthenium under
Ruthenium Speciation in Radioactive Wastes and State-of-the-art Strategies for its Recovery: A Review
Abstract Ruthenium, mainly 106Ru, is one of the notorious fission products present in radioactive wastes. In view of its complex chemistry, it gets partitioned into various processing streams during
Separation and recovery of ruthenium from nitric acid medium by electro-oxidation
Electro-oxidation method was employed for the separation of Ru as RuO4 vapour, from nitrosyl nitrate and simulated high level liquid waste (SHLLW) solutions. Separation of 95 and 54 % Ru were
Enhancing decontamination of zirconium and ruthenium in the Thorex process using acetohydroxamic acid
Abstract The decontamination of some extractable fission products, such as Zr and Ru, is an important issue in the Thorex process. Acetohydroxamic acid (AHA) is an organic ligand composed of only C,
Selective Partitioning of Ruthenium from Nitric Acid Media
ABSTRACT Ruthenium removal from PUREX raffinate solutions is imperative for the application of some advanced actinide partitioning technologies, particularly partitioning of hexavalent americium.
