Russell J Hand
Russell Hand is Professor of Glass Science and Engineering at the University of Sheffield and immediate Past-President of the SGT. His work in glass has focussed primarily on studies related to nuclear waste vitrification and on the mechanical properties of oxide glasses and he has (co-)authored ~140 refereed papers on these and other topics. He is also a member of Technical Committeee 5 (Waste Vitrification), 6 (Mechanical and Nanomechanical Properties of Glass) and 23 (Education) of the International Commission on Glass.

Hazmelt is a novel waste glass production unit based on the Apollo submerged element melter. As part of the development of the melter concept glass compositions have been developed for three representative intermediate level radioactive wastes: a sludge from a Magnox fuel storage pond, a contaminated soil waste and an ion exchange resin. Waste loading limits have been investigated for each composition with any crystalline phases formed being identified via a combination of XRD and Raman spectroscopy. Thermal analysis of the glasses has also been carried out. The chemical durability of the selected compositions has been investigated via the product consistency test. These glass development work and these results will be discussed along with the outcomes of the scaled-up melting of the glasses using the novel Hazmelt unit.
