Uranium ion yields from monodisperse uranium oxide particles [PDF]
Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2016 Secondary ion mass spectrometry (SIMS) plays an important role in nuclear forensics through its ability to identify isotopic ratios of particles accurately and precisely from samples obtained by inspectors [Boulyga et al., J. Anal. At. Spectrom. 30, 1469 (2015)].

Transient interactions of boron carbide with molten uranium oxide
Nuclear Materials and Energy, 2021 Thermodynamic equilibrium calculations have shown that, at the elevated temperatures anticipated during severe accidents, uranium oxide-boron carbide interactions are likely to result in significant boron volatilization and the formation of uranium ...
