Application of hydrogen permeation method in reactor experiments on investigation of hydrogen isotope interaction with structural materials

Abstract

The relevance of the study is caused by the necessity to develop methodical and instrumental bases for researching hydrogen isotope interaction with different materials under reactor irradiation. The main aim of the study is to develop and to test the technique on determining hydrogen isotope interaction parameters with structural materials under reactor irradiation; to carry out the estimates and experiments confirming the possibility of using the technique. The methods used in the study: thermophysical, neutron calculations methods of ampoule devices and method of hydrogen permeation were used. The results: The paper introduces the principle concepts of material reactor investigation technique using the hydrogen permeation method, estimates of the technique applicability and the results of its application at the reactor experiments with structural materials, such as steel SS316L (N)-IG, vanadium alloy V4Cr4Ti and copper bronze CuCrZr
