On the study of catalytic membrane reactor for water detritiation: Membrane characterization. [PDF]

open access: yes, 2013
Tritium waste recycling is a real economic and ecological issue. Generally under the non-valuable Q2Oform (Q = H, D or T), waste can be converted into fuel Q2for a fusion machine (e.g. JET, ITER) by isotopeexchange reaction Q2O + H2= H2O + Q2.

Evaluation of hydrogen permeation rate through zirconium pipe

open access: yesNuclear Materials and Energy, 2018
To launch a fusion reactor stably, it is necessary to prepare sufficient amount of tritium by an external tritium source. Tritium production using nuclear reactions by neutron and Li in a high temperature gas-cooled reactor (HTGR) is an attractive method.
