European RD Work on ODS steels

摘要

An increase in the maximum allowable operating temperature of future fusion power reactors is needed in order to improve the efficiency. Since the current conventional and reduced activation ferritic/martensitic steels have an upper temperature limit of about 550 C, the European Union has incorporated in her R&D work development of oxide dispersion strengthened steels. This presentation gives a summary of the work done so far and those planned for the next phase.
