Abstract
Reliability is an essential factor in safeguards measurements. The reliability is achieved if precision and accuracy of the measurements were according ESARDA’s target values. At the Brazilian Safeguards Analytical Laboratory a rigorous control of the DA measurements is made. The analytical method used to determine uranium concentration is Davies/Gray - NBL potentiometric titration. This paper describes the results obtained by LASAL.
