Abstract

|
The correlation of isotope composition of uranium, plutonium and neodymium with the burnup in PM uranium dioxide fuel has been investigated experimentally. The total and fractional(235U) bumup were determined by Nd-148 and, U and Pu mass spectrometric method respectively. The isotope compositions of these elements, after their separation from the fuel samples were measured by mass spectrometry. The contents of the elements in the irradiated fuel were determined by isotope dilution mass spectrometric method using M3 U, MN and 15ONd as spikes. The content of plutonium in the irradiated fuel was expressed by the correlation with uranium isotopes. The correlations between isotope compositions themselves and the total and fractional bumup were compared with those calculated from ORIGEN2 code.
