The Structural Materials Suite

The alloys that hold the machine together under load and neutrons.

Span

Magnet + blanket structure

Structural materials span cryogenic-tough magnet-case alloys and low-activation steels (RAFM, ODS) for the neutron-heavy breeder. Each is chosen for strength, toughness and — for the breeder — short-lived activation, and qualified against its service environment.

Material selection is inseparable from the neutron and safety cases.
