Stress and lifetime calculations for first wall and blanket structural components. Pt. 2
Description
In this report lifetime results for first wall components of a fusion reactor are presented. The aim is to show the general procedure for lifetime calculations, to demonstrate the principal mechanical behaviour of plasma faced structures, to consider effects of radiation on the behaviour of the material and assess lifetimes whithin the framework of fatigue crack growth analysis. The treatment of lifetime predictions is outlined in case of a first wall concept proposed by the NET-team for two materials, an austenitic steel (SS316CW) and a martensitic steel (1.4914). In general the results show a superiority of martensitic steel compared with austenitic steel. (orig.)

Der Bericht stellt Lebensdauervorhersagen fuer Komponenten der Ersten Wand eines Fusionsreaktors vor. Es wird die allgemeine Vorgehensweise fuer Lebensdauerberechnungen aufgezeigt, das typische mechanische Verhalten von plasmanahen Bauteilen unter Beruecksichtigung von strahlungsinduziert veraendertem Materialverhalten demonstriert, und eine Abschaetzung fuer die im Rahmen einer Ermuedungsrisswachstumsrechnung zu erwartenden Lebensdauer gegeben. Die Lebensdauervorhersage wird fuer ein von dem NET-Team vorgeschlagenes Erste Wand Konzept fuer zwei Materialien, einen austenitischen Stahl (SS316CW) und einen martensitischen Stahl (1.4914), durchgefuehrt. Die Ergebnisse zeigen guenstigere Vorhersagen fuer martensitischen gegenueber austenitischem Stahl. (orig.)
