Evaporation of UO2 Containing Pu Nuclides Formed during Irradiation

概要

論文の詳細を見る
Evaporation of NO2 containing Pu nuclides formed during irradiation is discussed on the basis of data from the mass spectrometry of NO2 specimen irradiated to about 8, 000 MWD/T burnup. The principal findings are that: (1) the ratio between Pu+ and U+ ion currents obtained from the vaporization-ionization process of the NO2 specimen was greater than the corresponding ratio of atoms present in the specimen; (2) in temperature dependency, the U+ ion current followed that of the NO2 vapor pressure, but no such correspondence was seen between the Pu+ ion current and the PuO2 vapor pressure.
