Detailed profiles of nuclear heating and radiation damage parameters were determined in ITER blanket modules at different poloidal locations. The results indicate that the nuclear parameters are sensitive to the configuration and material composition. Nuclear analysis was performed for several sections with cutouts in the back of the blanket modules for manifolds, inter-modular keys, and in-vessel coils to assess the impact on vacuum vessel shielding.
