| Abstract: | Neutron shielding structure of the ITER vacuum vessel (VV) will be applied to shielding neutron and gamma-ray and reducing the toroidal field ripple. The features of ITER vacuum vessel and the material selection for shielding structures are briefly discussed. A shielding conceptual design and some correlative support structures have been developed. The layout of ferromagnetic inserts was performed. Filling ratios of shielding materials between VV shells were acquired according to ITER VV physics calculation results. In term of the ITER VV design criteria, the detailed design work for library of the shielding blocks and the emulational structure have been finished based on the 3D modeling software. |
