Abstract

The Permeator Against Vacuum (PAV) is one of the candidate Tritium extraction and removal technology from the Lithium-Lead circulating in the breeding blanket currently under consideration for the EU DEMO. In this work the design of a PAV mock-up, dimensioned for the test in the TRIEX facility at ENEA Brasimone, is presented, together with a structural and fluid-dynamic analysis. The mock-up consists of parallel helical vanadium pipes inserted in a vacuum vessel, where the Tritium permeates from the PbLi. The extraction efficiency of the mock-up is computed using an established Tritium permeation model, demonstrating that the mock-up reaches the target 80% efficiency in nominal conditions. © 2017
