Description
The hydrogen isotopes Tritium and Deuterium will be the fuel of future fusion power plants. These isotopes will be in contact with components of the reactor, as well as with auxiliary systems. For safety studies and the overall Tritium budget, hydrogen transport parameters are necessary to perform according analyses. Reduced Activating Ferritic Martensitic (RAFM) steels at operation conditions with varying temperature between 300°C and 550°C can store and transport Hydrogen to a considerable extent. Also the knowledge of the transport parameters of austenitic steels will be needed for materials of pipelines and equipment in a power plant. Therefore, a qualified data base will be necessary for the future work.
Our contribution presents firstly an overview of transport parameters of different RAFM steels. Secondly a short review of austenitic steels for tubes and tanks, also regarding exothermic hydride generating materials. As third part the publication will review the transport parameter of elementary materials, generating understanding of the first both parts. The authors are preparing experiments for the determination hydrogen transport parameter of elevated temperature.
