Impact assessment of tritium in an ITER hot cell

► We estimate the time dependent tritium concentrations for the only VDS case and the ADS and VDS case. ► We compare the tritium recovering time for with and without tritium removal cases. ► Without tritium removal case is increased about 20 times as comparing that after tritium removal case. ► Tritium diffusion depth was estimated to clarify the influence of tritium release in the hot cell.
