Collaborative research to underpin radioactive waste management in the United Kingdom and Republic of Korea
University of Sheffield
Neil Hyatt was appointed to academic staff in 2003 as Lecturer in Materials Chemistry. He obtained his BSc and PhD in Chemistry at The University of Birmingham and held research appointments in industry and academia, before joining the Department in 2001 as Senior Research Fellow in the BNFL Immobilisation Science Laboratory. Neil is a recognised authority on radioactive waste management and was appointed to a Royal Academy of Engineering research chair in 2011, supported by the Nuclear Decommissioning Authority.

Research interests
Radioactive waste management and disposal
Our focus is on developing strategy, materials, processes and policy to support the safe, timely and efficient clean up of the UK radioactive waste legacy. A key aspect of our research is the design, manufacture and performance assessment of glass and ceramic materials for the immobilisation of plutonium residues, legacy intermediate level wastes, and high level wastes from reprocessing operations.
We work closely with industrial organisations, including Sellafield Ltd., the Nuclear Decommissioning Authority and National Nuclear Laboratory to address real world challenges of radioactive waste management.
Our work has supported development of thermal treatment strategy by Sellafield Ltd. and Nuclear Decommissioning Authority and the acceptance of vitrified intermediate level wastes wastes in conceptual designs for the UK Geological Disposal Facility.
Advanced nuclear materials
Research is focused on the development of new materials and processes for application in future nuclear fission and fusion fuel cycles. We are currently developing novel processing methods for advanced cermet fuels with application in naval reactor concepts, ceramic clad materials for accident tolerant nuclear fuels, and the application of molten salts technology to reprocessing of nuclear fuels. We are also working on new waste management strategies for future fuel cycles, to reduce the ultimate geological disposal footprint.
Structure-property relations in mixed metal oxides
Research is focused on the study of structure-property relationships in perovskite related oxides showing a range of useful physical properties such as high temperature superconductivity, colossal magnetoresistance and anisotropic magnetic exchange. Recent work has investigated structure-property relationships in layered perovskite ferroelectrric oxides and oxide-fluorides.
