Experimental study of binary mixture permeation of hydrogen and helium in nanocomposite MFI-alumina membrane for tritium processes

摘要

The nuclear reaction between hydrogen's isotopes deuterium and tritium is the most effective reaction for future fusion power plants. Tritium being very rare, it will be produced via ~6Li (n, a) within the breeder blanket to achieve self-sufficiency. In the solid blanket concept, the bred tritium is extracted using a helium stream of about 10~4 m~3/h doped with 0.1% H2. Most of the tritium recovery processes developed up to now are based on conventional technologies using condensation and adsorption/desorption techniques [1]. Alternatively, the Tritium Laboratory Karlsruhe (TLK) proposes a combination of catalytic membrane reactor PERMCAT with a pre-concentration stage using zeolite membranes. This would ensure a simple and fully continuous operation and smallest achievable tritium inventory [2].
