Overview of the development of neutronics instrumentation for the EU ITER TBM at KIT

Test Blanket Modules (TBM) will be installed in ITER with the aim to investigate the nuclear performance of different breeding blanket concepts. As partner of the European Consortium on Nuclear Data and Measurement Techniques in the framework of several F4E specific grants and contracts, KIT and ENEA have investigated ways to integrate neutron flux detectors into the TBM considering in particular mechanical restrictions and the harsh environment of the TBM. In the frame of ongoing research, several candidate neutron flux measurement techniques are investigated for their suitability to and operability under the harsh environment conditions in the TBM. The work at KIT focusses on a neutron activation system, self-powered detectors and silicon carbide detectors.
