Structure Materials in Fusion Reactors: Issues Related to Tritium, Radioactivity and Radiation-Induced Effects

M. Rubel

Fusion Science and Technology / Volume 61 / Number 2T / February 2012 / Pages 421-429

Status of Fusion / Proceedings of the Tenth Carolus Magnus Summer School on Plasma and Fusion Energy Physics

A concise overview is given on materials applied in fusion technology. The influence of plasma operation on the behaviour of reactor components and diagnostic systems is discussed with emphasis on effects caused by fast particles reaching the reactor wall. Issues related to primary and induced radioactivity are reviewed: tritium inventory and transmutation. Tritium breeding in the reactor blanket, separation of hydrogen isotopes and safety aspects in handling radio-contaminated components are also included.
