High entropy alloys (HEAs) are a novel class of material that have highly tailorable properties depending on their composition. In addition to the ability to tailor their properties, they can also be functionally graded enabling the joining of two dissimilar materials that would otherwise be difficult or detrimental to place in contact with each-other (a good example being Fe and Al). Coatings are being applied to accident tolerant fuels to improve their behaviour during an accident, for example a loss-of-coolant accident, reducing the corrosion rate and likelihood of fuel failure. This exciting project will highlight the potential for HEA use in water reactors and beyond, collaborating with other institutions, both nationally and internationally, focused on producing accident tolerant fuel cladding materials.This industrially focused project will combine a cutting edge atomic scale modelling methodology with targeted experiments to advance the field. The project will be highly industrially focused with the successful candidate being expected to present within a number of international consortia.

高熵合金（HEAS）是一种新型的材料，具有高度可调整的特性，具体取决于它们的组成。除了量身定制其性质的能力外，它们还可以在功能上进行分级，从而可以连接两种不同的材料，否则它们很难或与彼此接触（一个很好的例子是FE和AL）。涂料被应用于事故耐受燃料，以改善事故中的行为，例如，造成冷却剂事故，降低了腐蚀率和燃油故障的可能性。这个令人兴奋的项目将突出在水反应堆及其他地区进行重建的潜力，与国际和国际上的其他机构合作，专注于生产耐受的燃料覆盖材料。这项工业专注的项目将与尖端的原子尺度建模方法与有针对性的型号结合实验以推进领域。该项目将在工业上高度关注，预计成功的候选人将在许多国际财团内提出。
