The SDDR in the port interspace with WCCB TBM set was evaluated with MCNP5_D1S, and it was over 100 μSv/hr at 10^6 sec after shutdown. Counter measure of too high SDDR was proposed in present study. The SDDR could be decreased below 100 μSv/hr by using shims and B4C tiles., 12th ITER Neutronics Meeting}, title = {SDDR analysis in equatorial port interspace with WCCB TBM-set}, year = {2017} }
