For the operation of ITER with equimolar DT mixtures a rather complex chemical plant -the ITER tritium plant - is needed. Fuel cycle systems are designed to process considerable and unprecedented DT flow rates with high flexivility and reliability. Multiple confinement of tritium will be achieved through passive physical barriers and active detritiation systems. High decomtamination factor for effluent and release streams and low tritium inventories in all systems are required to minimize chronic and accidental emissions, respectively. The paper will provide an update of all aspects of the ITER tritium plant design, will report on construction supporting R&D and will identify issues remaining for the immediate future.
