An Integrated Modelling and Experimental Framework for Nuclear Fusion Materials Testing and Development PhD

Nuclear fusion offers the prospect of clean, abundant, and safe energy that could transform global energy systems. Achieving this goal depends on materials that can endure extreme environments within fusion reactors, especially plasma-facing materials (PFMs) exposed to intense heat fluxes and energetic particles. Understanding and predicting how these materials degrade under such conditions is critical to ensuring the longevity and safety of fusion reactors.

This PhD project focuses on developing an integrated framework that combines cutting-edge computational models, including Monte Carlo simulations and finite element analysis, with high-heat flux electron beam experiments. The research will simulate and replicate steady, cyclic, and transient thermal loads to better understand PFM behaviour. Experimental validation will be used to refine simulation accuracy and ultimately establish a reliable toolset for testing and developing fusion-relevant materials. 

Cranfield University is internationally renowned for its research into materials for extreme environments, offering state-of-the-art facilities and strong industrial collaborations. The project will be supervised by Dr Gregory Bizarri, an expert in radiation–matter interactions, computational modelling, and materials science, with a strong publication record (h-index 36, i10-index 69). Dr Francesco Fanicchia, Research Area Lead: Material Systems for Demanding Environments at the Henry Royce Institute, specialises in high-temperature coatings and materials testing and will co-supervise. This studentship is part of a collaborative project with UKAEA, providing opportunities for engagement with leading fusion research facilities. Together, they offer a wealth of experience in integrating simulation and experimental methods to solve real-world challenges in fusion energy.

The successful delivery of this project will provide a validated framework for assessing and predicting the degradation of plasma-facing materials under fusion-relevant conditions. This will accelerate the development and qualification of more resilient materials and coatings, contributing directly to the advancement of sustainable fusion energy. The techniques developed may also be applied in other sectors facing extreme material challenges, such as Aerospace and Defence.

The student will benefit from direct collaboration with UKAEA, gaining exposure to cutting-edge fusion research facilities and industry-leading experts. This project offers unique opportunities to contribute to pioneering experimental and modelling methods that will shape the future of fusion materials development. The student will also have access to Cranfield’s state-of-the-art laboratories and a vibrant research community, as well as chances to present their work at international conferences and build a professional network spanning academia, industry, and national research centres. Through this multidisciplinary project, the student will develop expertise in:

• Contribute to the development and operation of state-of-the-art high heat flux testing, simulating the extreme environments of fusion reactors.
• Harness advanced computational tools to model complex particle-material interactions and predict material lifespan under fusion conditions.
• Apply innovative materials characterisation methods to reveal fundamental structural and mechanical transformations.
• Uncover and quantify critical degradation mechanisms to inform the design of next-generation fusion materials.
• Translate sophisticated scientific data into impactful insights through clear communication to diverse audiences, including industry stakeholders and policymakers.
