Radial Distribution of Isotope Ratios in Spent Nuclear Fuels with Different Burnups

  • 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)

Description

During nuclear power generation, some isotopes are produced by the fission process causing the compositional changes in a nuclear fuel. The abundances of some isotopes provide information about fuel burnup. Direct analysis of fission products in a spent fuel by laser ablation inductively coupled plasma mass spectrometric analysis (LA-ICP-MS) was carried out to provide local chemical distributions of fission products from the core to the periphery of a fuel pellet. To have a better understanding of local chemical properties, spent nuclear fuels with different burnups from 30,000 to 60,000 MWd/MtU were chosen as sample specimens. The local burn up based on isotopic measurements of Np, Am, Cm by LA-ICP-MS are presented
