Atom probe tomography and microscale mechanical testing of neutron irradiated Sizewell B reactor pressure vessel steel

本项目的目的是了解应变时效和辐射对RPV钢的综合影响。无论是在观察监测样本方面，还是在使用先进技术(如APT)方面，这一主题在文献中都没有得到充分研究。通过使用APT，我们可以看到原子尺度上的成分变化，这使得我们能够测量位错和团簇上溶质元素的浓度。这一数据有可能进一步延长RPV钢的预期寿命，从而延长压水堆反应堆的寿命。

This project aim is to understand the combined effects of strain ageing and irradiation on RPV steel. This topic is understudied in the literature, both in terms of looking at surveillance samples and in terms of using advanced techniques such as APT. By using APT we can see the composition variations at the atomic scale allowing us to measure the concentrations of solute elements at dislocations and clusters. This data has the potential to further extend the life expectancy of RPV steels and therefore PWR reactors.
