A lecture given by Miles Stopher of the University of Cambridge, Department of Materials Science and Metallurgy, for the 2016 Literature Review Prize of the Institute of Materials, Minerals and Mining (London). The effects of neutron radiation on nickel-based alloys in thermal reactors are defying predictions that were made based upon accelerated testing in fast reactors. As nickel-based alloy components face significant doses in aging thermal reactors and their role in Gen-IV reactor designs becomes prominent, the literature on the effects of radiation on such alloys must be reviewed to enable better structural integrity assessments for relevant components and optimise alloys with respect to irradiation embrittlement resistance. This paper reviews the available data on the effects of radiation, notably neutron radiation, on nickel-based alloys and discusses the possible mitigation strategies and design opportunities for radiation embrittlement-resistant alloys based on recent developments in alloy computational design. The Materials Literature Review Prize of IOM3 aims to encourage the preparation of definitive, critical reviews of the literature by students as an essential part of study for a higher degree in the materials field, and subsequently make the best of these available to a wider readership. The prize is administered by the Editorial Board of MST (the journal Materials Science and Technology). Open to any postgraduate student studying in the UK or internationally, the prize carries a cash award, in line with other IOM3 prizes for papers. A winning entry and two runner-up prizes are awarded each year, and all entries are considered for publication in the journal subject to acceptance following peer-review. http://www.iom3.org/news/2016/jul/05/materials-literature-review-prize-winner-announced
