Abstract
The determination of burnup, an indicator of fuel cycle efficiency, ha s been accomplished by the determination of La-139 by high-resolution inductively coupled plasma atomic emission spectroscopy (HR-ICP-AES). Solutions of digested samples of reactor fuel rods were introduced int o a shielded glovebox housing an inductively-coupled plasma (ICP) and the resulting atomic emission transmitted to a high-resolution spectro meter by a 31 m fiber optic bundle. Total and isotopic U determination by thermal ionization mass spectrometry (TIMS) is presented to allow for the calculation of burnup for the samples. This method of burnup d etermination reduces the time, material, sample handling and waste gen eration associated with typical burnup determinations which require se paration of lanthanum from the other fission products with high specif ic activities.
