Evaluation of shielding is important for personnel access during maintenance work in ITER after plasma shut-down. The shielding in the equatorial port with WCCB TBM was studied. The peaked neutron flux around the gap between the TBM Frame and the port inner wall shows that effects of the gap are dominant to the shielding properties.
