Abstract:

Neutron measurement system should be able to provide neutron fluxes and spectra at beryllium multiplier and tritium breeder of the neutronics and ttritium production test blanket module (NT-TBM) during D-D and D-T phases in ITER. A special neutron diagnostic system has been proposed for measuring the neutron fluxes and spectra without interrupt to ITER operation. This system includes encapsulated foil activation system, micro-fission chamber detectors (MFC), and a compact neutron spectrometer as natural diamond detector (NDD).
