Separation of fission produced (106)Ru from simulated high level nuclear wastes for production of brachytherapy sources

An effective and simple process for the isolation of (106)Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by H(5)IO(6) in HNO(3) solution and was extracted to CCl(4) phase in the form of RuO(4). In order to obtain ruthenium in the suitable form for production of br...

Sumario:An effective and simple process for the isolation of (106)Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by H(5)IO(6) in HNO(3) solution and was extracted to CCl(4) phase in the form of RuO(4). In order to obtain ruthenium in the suitable form for production of brachytherapy sources, RuO(4) in organic phase was reduced and re-extracted to aqueous phase. The efficiency of extraction of (103)Ru to organic phase was 86 %, re-extraction to aqueous solution was near 100 %, so the overall recovery of (103)Ru is estimated at more than 80 %.
