ITER Materials R&D Data Bank

To keep traceability of many valuable raw data that were experimentally obtained in the ITER Technology R&D Tasks related to materials for In-Vessel Components, and to easily make the best use of these data in design activities, the `ITER Materials R&D Data Bank' has been built up, with the use of Excel TM spread sheets. Compared with existing material data banks, this data bank is unique in the following respects: (1) In addition to thermo-mechanical properties of single materials (beryllium, tungsten, carbon-based materials, copper alloys and stainless steels), thermo-mechanical properties (including neutron irradiation effects) for various kinds of joints between these materials, and the results of thermal fatigue tests of mock-ups are collected. (2) As for plasma facing materials (beryllium, tungsten and carbon), experimental data on plasma–material interactions such as sputtering, disruption erosion, and hydrogen-isotope trapping and release are collected.
