Tritium is one of the fusion fuel elements, and this has to be bred in the inner wall of the fusion reactor. As a hydrogen isotope, it is chemically very reactive, but it is also radio-active. It will remain in the machine elements and several interesting engineering challenges are open in order to make a fusion reactor successful. TRANSAT Project organises a Tritium Summer School, allowing students and young researchers to get updated on all the details.
From the website: "This 5-days event will consists of virtual invited lectures. The young generation of researchers working in fusion and fission research and development are encouraged to participate to gain knowledge. They will learn more on the challenges in the cross-cutting activities in fission and fusion on tritium together with waste management issues and biological studies applied to toxicology and dosimetry."
