Abstract

A study related to the separations of uranium traces in a concentrated Pu solution and plutonium traces in a concentrated U solution was performed (with Pu/U or U/Pu = 10²–10⁵). Its objective was to determine the U–Pu separation performances for a low U and Pu concentration range, namely: Pu solutions of 2.5 mg L⁻¹ to 2.5 g L⁻¹ containing traces of U (25 µg L⁻¹), U solutions of 10 µg L⁻¹ to 10 mg L⁻¹ containing traces of Pu (100 ng L⁻¹). The developed methods proved to be efficient and its robustness was confirmed with the treatment of high-activity real samples.
