This paper describes the design status of the ITER tritium plant. The key processing requirements and basis for process selection are summarized. Status of the remaining R&D efforts and selection of the process for impurity detritiation are also given. Evaluation studies for preliminary tritium plant processes were completed during the ITER Conceptual Design Activities (CDA) phase with an emphasis towards use of existing technology and proven industrial applications, where available [1]. Design of systems has continued during the Engineering Design Activities (EDA) phase. Layout designs are now available of most subsystems.
