Experimental estimate of tritium production parameters for RF Test Blanket Modul

Tritium Breeding Ratio (TBR) is a most value among controlled fusion reactor parameters. One in a targets of Test Blanket Module (TBM) program is experimental investigation of the value. On the whole TBR can be submitted for consideration TBR=BTB/BTP (BTB - breaded tritium in blanket, BTP - burned tritium in plasma). To investigate a numerator of the formula a tritium production in breeding zone (BZ) of the TBM have to be measured under ITER plasma experiments. A tritium and neutron monitoring system with some lithium and neutron sensors is proposed. Lithium ortho-silicate and lithium carbonate and the neutron detectors fit the task. Differences isotope lithium-6 and lithium-7 can be applied. For delivery/withdrawal of the detectors into/from the BZ a pneumatic concept is suggested with using channels allocated in submodule. Channels pass through the submodule back wall and reach the attended area. These channels allow the insertion during the dwell time or operational pauses of activation foil and capsules with material probes. Capsules for the detectors and a channel for feed of the capsules in TBM before pulse and extraction after pulse are presented in this paper. (orig.)
