[en] Neutronics analyses for Li/V-alloy liquid blankets with and without external beryllium were performed for the FFHR2 design in order to assess the tritium breeding ratios (TBRs) and neutron shielding performances. Beryllium multiplier improved the TBRs for both the Li/V-alloy and Flibe/V-alloy blankets. The shielding performance of the Li/V-alloy blanket with Be was greatly improved because the adequate TBRs can be obtained with the thinner breeding region than in the Li/V-alloy blanket without Be and the thickness of the shielding region was increased. On the other hard, the shielding performance of the Flibe/V-alloy blankets with and without external Be was comparable. It was shown that the Li/V-alloy and Flibe/V-alloy liquid blankets with and without solid Be satisfied the requirement for TBRs and shielding for the superconductor magnet of FFHR2. The activation of MHD coating of Er₂O₃ for the Li/V-alloy blankets and activation performance of the Flibe/V-alloy blankets were also investigated for the cases with and without external Be. The MHD coating of Er₂O₃ in the Li/V-alloy blankets introduced long-lived activation products. The activation of the Flibe/V-alloy blanket with external Be was comparable to that without external Be.
