Rapid Determination of Burn-Up of Nuclear Fuel—a Possible Approach

High performance liquid chromatography (HPLC) has been used for the separation and estimation of light rare earths by making use of an anion exchanger or a dynamically modified reverse phase column as a cation exchanger. Both these methods were studied and relative performance was assessed from the point of view of their suitability for the determination of burn-up of nuclear fuels.
