Magnetically separable Fe3O4-SiO2/Pt catalyst and its application for uranium reduction

Scientific Reports
Magnetically separable Fe3O4-SiO2/Pt catalysts with ~ 2% Pt loading have been developed for the generation of U(IV) in HNO3-N2H4 medium, used in the nuclear spent fuel reprocessing. Pt was impregnated in the catalysts via reductive heat treatment.

Application of isomorphic remote manipulators with haptic feedback in the development of automatic analysis equipment for spent fuel reprocessing samples

International Journal of Advanced Nuclear Reactor Design and Technology
Acid concentration and plutonium valence state in samples are crucial analytical parameters for process control during spent fuel reprocessing. Due to the high radioactivity and strong corrosiveness of reprocessing samples, remote operation is mandatory.

Reprocessing anaglyph images [PDF]

SPIE Proceedings, 2012
In related work, we have shown that conventional digital cameras easily can be modified to directly capture anaglyphs. Anaglyph images commonly have been used to encode stereo image pairs for viewing, but anaglyphs also can be treated as an efficient encoding of two-view image data for reprocessing.
