بررسی اجمالی از فعالیت های R & D در پردازش تریتیوم وبکارگیری فن آوری در JAEA

In JAEA, the tritium processing and handling technologies have been studied at TPL (Tritium Process Laboratory). The main R&D activities are: the tritium processing technology for the blanket recovery systems; the basic tritium behavior in confinement materials; and detritiation and decontamination. The R&D activities on tritium processing and handling technologies for a demonstration reactor (DEMO) are also planned to be carried out in the broader approach (BA) program by JAEA with Japanese universities. The ceramic proton conductor has been studied as a possible tritium processing method for the blanket system. The BIXS method has also been studied as a monitoring of tritium in the blanket system. The hydrogen transfer behavior from water to metal has been studied as a function of temperature. As for the behavior of high concentration tritium water, it was observed that the formation of the oxidized layer was prevented by the presence of tritium in water (0.23 GBq/cc). A new hydrophobic catalyst has been developed for the conversion of tritium to water. The catalyst could convert tritium to water at room temperature. A new Nafion membrane has also been developed by gamma ray irradiation to get the strong durability for tritium.

The R&D for tritium processing and handling technologies to a demonstration reactor (DEMO) are also planned to be carried out in the broader approach (BA) program in Japan by JAEA with Japanese universities. The ceramic proton conductor has been studied as a tritium processing method for the blanket system. The BIXS method has also been studied as a monitoring of tritium in the blanket system. An advanced BIXS monitor has showed the good performance at high temperature. The hydrogen transfer behavior from water to metal has been studied as a function of temperature. It was expected that the surface of iron piping was oxidized to magnetite, and then deuterium generated by Schikorr reaction permeated though the iron piping. As for the behavior of high concentration tritium water, it was observed that the formation of the oxidized layer was prevented by the presence of tritium in water (0.23 GBq/cc). The tritium behaviors in concrete materials and in the epoxy paint have been studied to evaluate the function of the tritium confinement. A new hydrophobic catalyst has been developed for the conversion of tritium to water. The catalyst can function at room temperature even with the condition of the saturated water vapor. A new Nafion membrane has been developed by gamma ray irradiation. The large radiation durability of the membrane was obtained as the result of the crosslinking of polymers.
