Structural materials for fusion reactors

摘要

In order to preserve the conditions for an environmentally safe machine, at present the selection of materials for the structural components of fusion reactors is made of only on the basis of adequate mechanical properties, behaviour under irradiation, and compatibility with other mate- reals and cooling media, but also on their radiological properties, i.e. radioactivity, decay heat and radiotoxicity. These conditions strongly limit the number of suitable materials to a few families of materials, the alloys resulting from the application of these ideas and the main issues and problems with their use in fusion environment are discussed.
