Partitioning of plutonium from uranium is an important step in the reprocessing of spent fuel by PUREX process of solvent
extraction using 30% TBP-dodecane. This is achieved by selectively reducing the Pu in solution to least extractable trivalent
state by uranous nitrate as the reductant. The latter is conventionally produced by electrolytic reduction of uranyl ion in
presence of hydrazine nitrate as uranous nitrate stabilizer using Pt-coated titanium as the anode. The anode plating wears
out after period of operation thus affecting the process efficiency and hence the quality control testing of platinum plated
electrode becomes important. This article describes the use of Beta backscattering method with strontium-90 radioisotope as
non-destructive testing tool for measuring the coating thickness of the sample Ti electrode. The surface characteristics and
coating morphology were also examined by scanning electron microscope and the micrographs are presented.
