Evolution of nanostructure and properties in nuclear graphite with irradiation damage

有许多不同等级的石墨，例如，英国的agr使用的是中等粒度的Gilsocarbon石墨，但它们不再是可复制的，对于GenIV的设计，必须设计和生产新的石墨材料，但其中许多都有发现颗粒。问题是这些细粒石墨的工作效果如何，我们能否将积累的知识直接应用于历史等级？随着操作条件越来越苛刻，我们能否简单地线性外推已知的包络线？为了回答这些问题，并支持我们的核裂变反应堆的长期安全运行，以及支持物理科学的探索，我们需要培养下一代核石墨专家。在这个项目中，我们不仅会为您提供与世界级石墨专家一起工作的机会，还会为您提供独特的设施，我们还会考虑您下一阶段的职业发展，大力支持您的技能发展。我们的首要目标是帮助您成功成长为核石墨领域的专家，为国际核石墨界做出贡献。中子和质子辐照样品由英国国家核实验室、EDF能源公司、英国爱达荷国家实验室和美国费米实验室提供，它们储存在布里斯托尔大学和英国原子能机构（Culham），供您的项目使用。您将使用一系列技术，包括x射线衍射/断层扫描，聚焦离子束断层扫描，拉曼光谱和透射电子显微镜来研究材料的纳米/微观结构的演变，并将它们与局部热性能和机械性能相关联。

There are many different grades of graphite, for instance, the UK AGRs are using medium grained Gilsocarbon graphite but they are no longer reproducible and for GenIV designs, new graphite materials have to be designed and produced but many of them have finder grains. The question is how well do these fine grain graphite work and will we be able to directly apply our accumulated knowledge on historical grades? As the operation conditions get harsher can we simply linearly extrapolate the known envelope? To answer these questions and to support the long-term safe operation of our nuclear fission reactors as well as underpin the exploration of physics science in general, we need to foster next generation of experts in nuclear graphite.In this project, we will not only provide you the opportunity to work with world-class graphite experts, access to unique facilities but also we will have your next stage career development in mind to strongly support your skills development. Our primary aim is to enable your success and grow into an expert in nuclear graphite to contribute to nuclear graphite community internationally.Neutron and proton irradiated samples have been provided by UK National Nuclear Laboratory, EDF Energy, UK Idaho National Laboratory and US Fermi Lab, and they are stored at the University of Bristol and the UK Atomic Energy Agency (Culham) for your project. You will use a range of techniques including X-ray diffraction/tomography, Focused ion beam tomography, Raman spectroscopy and transmission electron microscopy to study the evolution of the nano-/microstructures of the materials and correlate them to the local thermal and mechanical properties.
