Standard Practice for The Separation of Lanthanide Elements from Uranium Matrices Using High Pressure Ion Chromatography (HPIC) for Isotopic Analyses by Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

Importancia y uso:

5.1 The measurement of isotopic distributions for the lanthanide series elements is of important to all phases of the nuclear fuels cycle. Examples include the purification of the Nd isotopes from Ce and Sm isotopes for the determination of atom percent fission through the production of ¹⁴⁸Nd in irradiated nuclear fuels using Practice C1769, determination of rare earth content and isotopic distribution in Uranium Ore Concentrates (UOC) for source term and production of lanthanide fission products in irradiated nuclear fuels for determination of performance, improvements of depletion codes, and analysis of burnup indicators.4
