Abstract
An ITER TBM mock-up made of lithium-lead and sheets of EUROFER was irradiated with short pulses of DT neutrons from the neutron generator at TU Dresden, and time-of-arrival spectra of the slow neutron flux were measured by means of a 3He counter in two regions inside the mock-up. Fast neutron spectra were obtained by continuous irradiation of the mock-up with DT neutrons and application of a NE-213 spectrometer. The same mock-up was also irradiated at the Frascati Neutron Generator and tritium production rates were measured by means of Li2CO3 pellet detectors and LiF thermoluminescense detectors (TLD) inserted into the mock-up. In case of the first type of detectors, the accumulated tritium activity was measured while with the LiF TLD the tritium production rate was obtained from the dose deposited in the detector by the tritium-producing reactions. The Calculation/Experiment ratio for the TPR measurement was nearly 1.0 with an uncertainty of approximately 7.4%. Preliminary results from calculations with FENDL-2.1 and JEFF-3.1.1 suggest a good agreement between experiment and calculation.
