IRRADIATION OF 1ST WALL STRUCTURAL-MATERIALS

The first wall of fusion reactors is subjected to harsh loading condit ions, in terms of neutron irradiation, thermal and mechanical load and surface erosion processes. Special devices have been developed at the High Flux Reactor (HFR) Division in Petten, The Netherlands, to repro duce as close as possible the typical fusion reactor operating conditi ons to evaluate the real operating limits of the first wall materials. The present article describes on-going irradiations on first wall str uctural materials.
