To develop the membrane pumping technology by means of superpermeable membranes at RFNC-VNIIEF in the "Prometheus" setup, the experiments on superpermeation of hydrogen isotopes through metal membranes were carried out.
The experimental results on superpermeation of thermal atoms of hydrogen isotopes including tritium through a cylindrical vanadium membrane are presented. The possibility of effective pumping, compression and recuperation of hydrogen isotopes by means of superpermeable membrane was demonstrated. The evaluation of membrane pumping rates and asymmetry degree of pure vanadium membrane was given.
The work was performed under the ISTC-2854 project.
