Profile

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.

He served as Head of the Department of Materials Science & Engineering from 2015-18, leading the Department to outstanding success, achieving 100% student satisfaction, 100% student employability and a record high annual research income of £23M in 2017.

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 the development of a thermal treatment strategy by Sellafield Ltd. and Nuclear Decommissioning Authority and the acceptance of vitrified intermediate-level 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 ferroelectric oxides and oxide-fluorides.

Neil has is active in public and media engagement, providing expert commentary on nuclear energy issues and supporting the public understanding of science.

He worked with designer Zoe Papadopoulou, to co-create the interactive Nuclear Dialogues installation with the Nuclear First DTC. The exhibit was shown at the EPSRC Impact! Exhibition at the Royal Academy of Art, displayed in the Wellcome Trust window, and as far afield as the Bejing International Design Festival.

Neil also contributed to a BBC Radio 3 documentary 'Staying Bright – A Century of Stainless Steel', describing the important role of this material in the nuclear industry. Following the partial meltdown of the Fukushima reactors in 2011, Neil has provided expert comment in more than 20 radio and television interviews and over 30 news articles published in print and online.
