Applications are invited for a research studentship in the field of fatigue crack growth, leading to the award of a PhD degree. The post is supported by a bursary and fees (at the UK student rate) provided by an EPSRC Industrial Case Award in collaboration with EDF Energy. Candidates should fulfil the eligibility criteria for the award https://www.ukri.org/what-we-do/developing-people-and-skills/esrc/funding-for-postgraduate-training-and-development/eligibility-for-studentship-funding/
EDF UK own and operate the UK nuclear power plants including Sizewell B Pressurised Water Reactor (PWR), which is looking to seek lifetime extension, from 2035 to at least 2055. EDF are also constructing EPRs at Hinkley Point C and Sizewell C. These plants are a crucial contribution to the UKs ambition of achieving net-zero carbon emissions. The UK regulatory regime requires defect tolerance to be demonstrated for high integrity components. Fatigue is one of the key degradation mechanisms that can affect the integrity of key PWR components. It is therefore necessary to demonstrate that fatigue crack growth from postulated manufacturing defects is tolerable over the plant lifetime.
The main aim of this work is to develop improved methods for predicting fatigue crack growth for complex loading histories relevant to typical PWR components. This will be achieved by using a combination of novel experimental techniques and analysis methods. The expected outcome of the PhD is a recommendation to industry on the most appropriate way to predict fatigue crack growth for complex PWR component loading histories, which may include a significant contribution from welding residual stresses.
You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will hold a 2:1 or 1st (or equivalent) class honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in fracture mechanics and experimental testing is essential. Good team-working, observational and communication skills are essential.
