Uranium Diboride is an exciting new nuclear material, which has great potential as an Accident Tolerant Fuel. This class of fuel materials is under intense international development as a result of the nuclear accident at Fukushiima, alongside the desire to reduce active safety requirements within commercial nuclear plants. During this programme, the PhD student will work alongside an established research team, with a dedicated PDRA also engaged on UB2 composite research. The student will manufacture and characterise UB2/UO2 composites using the state-of-the-art nuclear fuel labs at the Nuclear Fuel Centre of Excellence based in the Department of MACE. They will work at the pellet scale, reproducing industrial techniques including working with UO2 powders procued at the Springfields fuel fabrication facility, cold pressing using high-quality hold down systems and hydrogen sintering. They will characterise the manufactured pellets using a range of scientific techniques, including optical and electron microscopy, X-ray diffraction and thermo-physical measurements. Results will be used to further optimise the manufacture of composite pellets and develop industrially scalable fabrication routes.

二硼化铀是一种令人兴奋的新型核材料，作为耐事故燃料具有巨大的潜力。由于福岛核事故以及降低商业核电站主动安全要求的愿望，此类燃料材料正在国际上得到大力发展。在此计划期间，博士生将与一个已建立的研究团队一起工作，还有一个专门的 PDRA 也从事 UB2 复合材料研究。学生将使用 MACE 系核燃料卓越中心最先进的核燃料实验室来制造和表征 UB2/UO2 复合材料。他们将在颗粒规模上进行工作，复制工业技术，包括使用斯普林菲尔德燃料制造厂生产的二氧化铀粉末、使用高质量压紧系统进行冷压以及氢气烧结。他们将使用一系列科学技术来表征制造的颗粒，包括光学和电子显微镜、X 射线衍射和热物理测量。研究结果将用于进一步优化复合颗粒的制造并开发工业规模化的制造路线。
