Rapid estimation of uranium concentration in aqueous process solutions

Based on the Masson relation, Kumar and Koganti proposed a re-parameterized equation of density of aqueous solutions of mixed electrolytes of interest to the reprocessing of spent nuclear fuel. The adjustable parameters a₁, a₂, b₁, b₂ were regressed by multiple linear regression from the huge data base of PUREX density data containing more than 1000 points. Now the uranium concentration C₁ can be simply estimated by finding roots of the cubic Eq.2 numerically, provided density ρ_m and acidity of the solution C₂ are available. Experimental data, generated at RpG and reported data of NFC, was used to estimate uranium concentrations by roots function of GNU Octave 7.3.0. Out of three roots, only one root will be real and will have to be taken. An excellent comparison between experimental and predicted uranium concentrations was observed. Proposed method can be utilized for rapid estimation of uranium concentration in aqueous solution just by measuring its density and acidity by instrumental means
