This paper describes removal and control of tritium of liquid lithium (Li) target for IFMIF. To produce intense neutrons, 40 MeV deuteron beam with a current of 250 mA is injected into a liquid Li flow with a speed of 20 m/s. D-Li reaction produces tritium with a production rate of 7 g/y. Tritium in Li is removed by a hot trap with an yttrium getter and controlled less than 0.65 appm. As an option, a swamping method with a cold trap is investigated.
