[en] A set of common used ancillary tritium processing systems including the tritium extract system (TES), the coolant purification system (CPS), and the tritium measurement system (TMS) have been designed for the two types of Chinese test blanket modules (TBM) located in a whole test port in the international thermonuclear experimental reactor (ITER), based on the structure features and technical parameters of Chinese helium cooled solid breeder (CHHCSB) and dual functional lithium lead (DFLL) TBMs. The functions, technical parameters, and process flows of these systems have been described. TES is designed to extract tritium produced in the breeder, to store and separate hydrogen isotope gases. Impurities and tritium in the helium coolant is removed through CPS. TMS has the function of testing the tritium breeding rate in TBM which sometimes replaces the function of TES. Tritium release to the environment from two types of Chinese TBMs and the common tritium systems is well controlled below the tritium safety limit of ITER, based on the tritium permeation and tritium safety analysis.
