Progress of China's TBM tritium technology

The TES, CPS and TMS are very important ancillary systems for operation of the TBM because most of the TBM experiment data will be got by operation of these systems. This paper introduces the progress of the R&D on these systems. A hydrogen isotope separation subsystem is integrated into the TES for accurate measurement of tritium as well as less tritium contamination hydrogen release into the environment compare with the original design of the TES. A tested assembly of a TES based on the results has been designed based on the results. Experiment results on the components show that the present design is feasible.

► Tritium related technology is one of the most important research fields in China ITER TBM program.
► The ancillary systems will be built for evaluation of the tritium self-sufficiency as well as energy extraction technology for future fusion reactor design.
► We present the brief introduction of the R&D on the ancillary systems.
