During my master’s in fusion, I had the opportunity to do an internship at UKAEA in Culham, where I worked on data from MAST Upgrade. With support from this funding scheme, I was able to spend several weeks in the UK and experience fusion research in practice.

My name is Feras Tellawi, and I am a graduate of the European Master in Nuclear Fusion and Engineering Physics (FUSION-EP) program, specializing in fusion neutronics.Following my graduation, I continued my work in fusion neutronics research through an internship at the Institute of Plasma Physics of the Czech Academy of Sciences in Prague, Czech Republic. This internship, funded by FuseNet, focused on the development of a detailed neutronics model for the COMPASS-U tokamak using Monte Carlo particle transport methods.

For my internship within my master of Nuclear Fusion, I wanted to do a project connected to the research group of Energy Systems and Control at DIFFER. This area of research sparked my interest and therefore I went to the group leader of this group to discuss the options. Lucky for me, an experiment was planned at NIFS in Japan for which they needed someone on-site during my preferred quartile, and I did not hestitate to agree to this great opportunity.

Lars de Reus · Combined AP/NF internship · TU/e Applied Physics · May 2026 Last semester I spent several weeks across two countries working on vacuum ultraviolet (VUV) diagnostics for JT-60SA — currently the world's largest superconducting tokamak, located in Naka, Japan. The internship was split between installation work in Japan and optical design work at Consorzio RFX in Padua, Italy. Here's how it went.What is a VUV diagnostic?

This winter, I had the opportunity to complete my internship at the University of Edinburgh as the final part of my Master Applied Physics. I joined the PPE (Particle Physics Experimentation) group at the School of Physics and Astronomy, which turned out to be a very valuable and enjoyable experience. 

From September 2025 to March 2026, I had the opportunity to carry out my internship at the laboratories of the Instituto de Plasmas e Fusão Nuclear (IPFN) at Instituto Superior Técnico (IST) in Lisbon. During this period, I worked on the research for my Master's thesis in Nuclear Engineering at Politecnico di Milano. This experience was made possible thanks to the support of the FuseNet funding programme for M.Sc. students.

I participated in the Fusion and Plasma Lab in Ulsan National Institute of Science and Technology as a Visiting Student Researcher from September 15 to January 6. This short internship as a researcher prepared me for my PhD. From day to day coming to the office and reading, discussing and thinking about my research topic, it accustomed me to the daily struggles of a PhD student.

The deuterium and tritium fuel inside a fusion reactor will only have a burn-up fraction of 1-2%, and therefore requires to be looped through a fuel cycle. Understanding the surface interactions of tritium with materials in a fusion power plant’s fuel cycle is essential for tritium accountancy and maintenance, given its radioactivity. Therefore, I have studied this for my graduation project at the Tritium Laboratory Karlsruhe (TLK). My project was titled "In-situ tritium contamination and ozone decontamination of fusion-relevant materials."
