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.
