Tritium permeation barrier has been developed in order to mitigate tritium loss in most fusion blanket concepts. In this presentation, chemical behavior of tritium permeation barrier coatings under solid breeder blanket conditions is reported for the first time through compatibility tests using solid breeder pebbles.
