Abstract

For the design and construction of ITER, the determination of effects of short transient events like edge localized modes (ELMs) has become an important issue, especially in combination with the expected deterioration of material properties caused by neutron irradiation. Hence this study deals with the evaluation of the influence of radiation effects on the thermal shock resistance of potential plasma facing materials like pure tungsten, W-Re or W-La2O3 as well as graphite and carbon fiber composites (CFCs) which were exposed to a neutron dose of similar to 1 dpa (in carbon) at T=200°C. In situ observations at room temperature during single and multiple shot loadings (
