This PhD project supports the Nuclear Forensics (Provenance) programme through the understanding and characterisation of the effects of radioactive ageing on morphology and microstructure. The results of this project will provide valuable reference data to support the wider National Nuclear Forensics Library (NNFL) programme.Nuclear Forensics is the science of determining the identity, history and origin of nuclear or other radioactive materials, and as such is a critical component of security and safeguards controls. Through the characterisation, analysis and interpretation of their properties, nuclear materials can be linked to the processes by which they wereproduced and through which they have assumed their current form.This PhD project presents an exciting opportunity to investigate how these nuclear forensic signatures of plutonium dioxide evolve as a result of radioactive decay and ageing processes, through the use of multiscale modelling and simulation techniques. The project will be highly industrially focussed, working with key partners from the UK's Nuclear Forensics capability, and as such the successful candidate will be expected to present within a number of national and international fora. Applications are welcomed from candidates with a strong undergraduate interest and/or background in materials science, engineering, physics or chemistry.

这个博士项目通过理解和表征放射性老化对形态和微观结构的影响来支持核法医学（起源）计划。该项目的成果将提供宝贵的参考数据，以支持更广泛的国家核法证图书馆方案，核法证是确定核材料或其他放射性材料的身份、历史和来源的科学，因此是安全和保障监督的一个重要组成部分。通过表征，分析和解释其属性，核材料可以联系到他们werreproduced的过程，并通过它，他们已经假定其当前的形式。这个博士项目提供了一个令人兴奋的机会，调查这些核法医签名的二氧化钚演变作为放射性衰变和老化过程的结果，通过使用多尺度建模和模拟技术。该项目将高度集中于工业领域，与英国核取证能力的主要合作伙伴合作，因此，成功的候选人将有望在一些国家和国际论坛上发表演讲。申请欢迎具有强烈本科兴趣和/或材料科学，工程，物理或化学背景的候选人。
