... Impact tests were performed on one-third size specimens of six low activation steels developed for structural applications in fusion reactors. Specimens were irradiated to ∼30 dpa at ∼375°C in the Fast Flux Test Reactor. Comparison of the results with those of control specimens and specimens...

... Alloys with reduced long-life radioactivity (low-activation alloys) are being developed to increase the acceptability of fusion power. The phase stability and swelling resistance of a 12Cr-6.5Mn-lW-0.3V-0.1C martensitic steel were evaluated by transmission electron microscopy following 3.8-MeV...
