摘要
Test Blanket Modules (TBM) will be installed in the experimental reactor ITER with the aim to investigate the nuclear performance of different breeding blanket designs for future power fusion reactors. KIT is developing a neutron activation system for the measurement of neutron flux densities in selected positions in the TBM based on pneumatic activation probe transport. A preliminary engineering assessment of the pneumatic transport system has been performed and extensive irradiation tests of selected activation materials irradiated with 14 MeV neutrons from an intensive DT neutron generator were done. Here we summarize the results of the engineering assessment and focus in particular on the results of the irradiation tests and the uncertainty of the measurement method.
