Description

Future inertial fusion energy (IFE) reactors will require materials capable of surviving repeated exposure to intense X-ray radiation, energetic particles, and debris generated during target implosions. Understanding how these extreme conditions affect reactor materials is essential for the development of reliable fusion power plants.

This contribution presents laboratory and computational studies of radiation damage in candidate materials for future IFE reactors. Topics include EUV laser irradiation of tungsten-based alloys and pyrolytic boron nitride [1], comparison of experiments with XTANT-3 simulations [2], the influence of elevated temperature [3] and pre-existing radiation damage on material performance, and experimental approaches for studying damage caused by debris impacts under fusion-relevant conditions.
