Shielding conceptual designs of ITER TCP ports to protect electronics

•Scoping nuclear analysis of ITER Torus Cryopump for critical electronics protection.•Neutron flux maps at B1 level of the Tokamak Complex are generated for each shielding configuration.•Proposed shielding configurations have been implemented in the final design of the ITER Torus Cryopump due to their high shielding efficiency against plasma neutrons.•A shielding configuration which results are compatible with the limit of electronics in the shielded corners of B1 level is proposed.
