Ageing of plutonium oxide powders: evolution of physical properties

核取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，因此是安全和保障控制的关键组成部分。通过对其性质的描述、分析和解释，可以将核材料与它们的生产过程联系起来，并通过这些过程使它们具有目前的形式。这个博士项目提供了一个令人兴奋的机会，通过使用多尺度建模和模拟技术，研究这些核法医特征是如何随着放射性衰变和老化过程而演变的。该项目将高度以工业为重点，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。欢迎具有材料科学、工程、物理或化学专业本科兴趣和/或背景的候选人申请。

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 were produced 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.
