Analysis of Novel 3D Printed Tungsten Lattices for Nuclear Fusion Applications – Materials Strand Project

Supervisors: Aneeqa Khan, Paul Mummery, Ed Pickering (University of Manchester) & Frances Livera, (UKAEA). 

The development of plasma facing materials that can withstand the associated challenging environment (14 MeV neutrons, extreme heat loads (>10MW/m2)), all while having complex geometrical requirements is an immense challenge for fusion reactors. Typically, plasma facing components have been produced from materials such as tungsten using traditional manufacturing techniques. However, there are challenges in shaping and joining dissimilar materials associated with this. Recently advances in 3D printing technology have made it an attractive option, despite known issues around porosity, cracking and very different material properties in comparison to traditionally manufactured material.

This project, in collaboration with the UK Atomic Energy Authority (UKAEA) will look at analysing various novel 3D printed tungsten lattices using techniques such as electron microscopy, residual stress measurements, thermal conductivity measurements and hardness testing. There will also be a need to test these materials under fusion relevant conditions, to determine whether they will be able to withstand the harsh environment of a fusion reactor.

The results from this work will determine the feasibility of novel 3D printed tungsten lattices for fusion applications. This will feed into UKAEA’s materials work and will also contribute to the wider fusion materials community.

To summarise the objectives of the project:

  • Source novel 3D printed W lattices
  • Carry detailed experimental characterisation in the ‘as-received’ state
  • Carry out detailed experimental characterisation following exposure to fusion relevant environments
  • Make recommendations on the most viable materials.

The project is based in Manchester but will involve collaboration with UKAEA.

During the first six months of the PhD, materials strand students will typically travel to attend taught modules at all six of the Fusion CDT partner universities.
