| Abstract Scope |
This presentation will highlight activities in the United States over the past year to quantify the proximity of several fusion concepts to a true fusion neutron spectrum in terms of materials evolution under irradiation by quantification of a selection of materials performance metrics. The analysis performed involves the participation of experts in the areas of neutronics, transmutation and chemistry changes, computational thermodynamics, primary damage production, and long-term microstructural evolution. The studies have been conducted for materials catalogued as primary candidates for structural applications in fusion reactors: reduced-activation ferritic-martensitic steels, vanadium alloys, tungsten alloys, and silicon carbide. The neutron spectra evaluated for prototypicality include several DEMO concepts, the ITER spectrum, a D/Li-stripping source, and a pulsed irradiation spectrum representative of inertial fusion energy concepts. We will present the main results of the numerical evaluation in terms of transmutant and primary damage production, thermodynamic phase analysis, and long-term microstructural evolution. |
