The R and D status of ITER SDS

The ITER tritium storage and delivery system (SDS) is still in pre-conceptual phase. The major functions of ITER SDS are composed of tritium storage in a safe way, rapid fueling based on the plasma scenario and tritium inventory accountancy in a day schedule. The ITER SDS will be delivered to the ITER site as a set of glovebox modules which have every tritium compatible components in its space for tritium confinement and are to be assembled together at the ITER tritium building. Meanwhile there have been some reports for the ITER SDS' R and D activities and progress, the current R and D status is still on-going at the pre-conceptual design (CD) phase. The scope of current R and D has been rearranged with the depleted uranium (DU) oriented experiments for the future ITER application. This report deals with the current status and activities, especially setup of handling procedure, test devices and facility design based on DU getter material, for CD completion of the ITER SDS next year.
