Measurement of the Fission Product ¹⁴⁸Nd  in the Irradiated Nuclear Fuel by ID-MC-ICPMS

The isotopic abundance and mass fraction of the fission product ¹⁴⁸Nd in the irradiated nuclear fuel were measured with ID-MC-ICPMS. The stability of mass spectrometry instrument was tested using two kinds of standard materials and the difference of two correction factors was less than 0.001%. The mass fraction of enriched isotope ¹⁴⁴Nd was determined by using the high pure natural neodymium as the spike. Then the mass fraction of ¹⁴⁸Nd in the irradiated nuclear fuel was determined by the certified enriched ¹⁴⁴Nd as the spike. The isotopic abundance and mass fraction of ¹⁴⁸Nd in the fission products is 0.088 7±0.001 2 and (4.65±004) ng/g respectively.
