Description

Low level radioactive waste (LLW) having Cs and Sr activity is decontaminated by chemical co-precipitation method at LWTP Tarapur. Chemicals like copper sulphate, potassium ferrocyanide, ferric nitrate, barium chloride and sodium sulphate are being used for above work. However, this method does not offer any decontamination for ruthenium due to its complex nature. For removal of ruthenium, separate treatment schematic is required which should take care of other fission products like Cs and Sr also. A combined chemical treatment method has been evolved for removal of ruthenium along with Cs and Sr. This method offers advantages of single step due to its combined nature, better decontamination factor (DF) for all the radionuclides, reduction in sludge volume, reduction of man rem expenditure etc. This method has been successfully adopted on the plant scale at LWTP, Tarapur.
