Tritium International Conference in Busan (South Korea)

Last week the studies performed with TRITIUM toolkit about the isotopic effect on tritium permeation in breeding blankets were presented during the 12th International Conference on Tritium Science & Technology (

Carlos Moreno, from CIEMAT, was in charge of this presentation. CIEMAT and Empresarios Agrupados have been working together in the development of this tritium simulation area.

In this work, the effect of co-permeation and counter-permeation of hydrogen isotopes has been studied. Using the tritium transport simulation library in EcosimPro, the past experimental results have been successfully reproduced and the addition of hydrogen as a mitigating agent for the permeation in the different european blanket designs has been confirmed considering DEMO and ITER operational conditions.
