摘要	ITER neutronics model (Tokamak Complex) keeps evolving, and each development requires comprehensive transport analysis for verification and validation. The tokamak complex's bio-shield plugs are the main shielding barriers between the tokamak and the port cells. Therefore, shielding analysis and optimization for the bio-shield plugs are part of the key factors for ITER licensing. In this work, performance evaluation of two designed bio-shield plugs: IVVS-port cell #3 and TCP-port cell #4 in level B1 has been conducted. Neutron transport calculation analysis on the new designs (generic designs) showed total neutron flux of 1.71 x 10(6) n/cm(2)/s and 2.86 x 10(5) n/cm(2)/s respectively in a specified tally cell behind the IVVS and TCP bio-shield plug. Spatial neutron distribution behind the bios-shield plug (port cells) showed significant shielding improvement compared to the original IVVS and TCP bio-shield design. Further iterative optimized shielding scheme has been proposed to reduce the total neutron flux from 1.71 x 10(6) to 8.8 x 10(4) n/cm(2)/s and from 2.86 x 10(5) to 6.4 x 10(4) n/cm(2)/s for the respective tally cell behind IVVS and TCP bioshield plugs.
