Abstract :
The Storage and Delivery System (SDS) of the ITER Tritium Plant has to safely handle the fuel gases including tritium and deliver those gases to the Fuelling System (FS). Recently the ITER fuelling scenarios have been developed in more detail considering ramp-up, flat-top, and ramp-down. With this as input, an alternative analysis was performed for how SDS will support ITER inductive, hybrid, and non-inductive plasma operations. The fuelling rates from SDS to FS were evaluated. To supply gas to FS, SDS must draw gases from one or more sources. These sources could be SDS tanks, SDS hydride storage beds or the Isotope Separation System. Case studies were performed to evaluate the relative merits on various configurations. For inductive operations, it was found that tritium could be supplied with either 27 hydride beds and one tank or with 12 beds and four tanks. For deuterium supply the results were either 43 beds and one tank or 31 beds and four tanks. Also studied were options for distributing supporting gas inventories elsewhere in the Fuel Cycle or on larger hydride beds. Evaluation criteria included operability and safety.
