We just got a preprint available in arXiv.org for the general audience: "Fabrication of bulk delta-phase Zirconium Hydride from Zircaloy-4 for use as moderators in microreactors" (arXiv:2305.02249v1) In this manuscript, we performed a complete electron-microscopy characterization of the delta-phase Zirconium Hydride (delta-ZrH) currently under manufacturing, research and development to be used as moderator materials in … Continue reading New H-based materials for use in micro-nuclear-reactors

Are TiN coatings appropriate candidates for accident tolerant fuels?

October 9, 2018November 22, 2020 ~ Matheus A. Tunes ~ Leave a comment

I am so delighted to announce that our paper "Energetic particle irradiation study of TiN coatings: are these films appropriate for accident tolerant fuels?" has just been accepted for publication at the Journal of Nuclear Materials! In this study, we have used heavy ion irradiation in situ within a Transmission Electron Microscopy to investigate whether Titanium Nitride … Continue reading Are TiN coatings appropriate candidates for accident tolerant fuels?
