The single contributions for this report were presented on IV . Conference the about Hydrogen- and Tritium-Permeation in the KFA Jülich. Under the first two titles, after a remark concerning the diffi- culties and aims, an introduction into the experimental requirements of the permeation measurements in the IRE of the KFA is given. It is reported about results of varied tests on corroded tube samples and the following investigation of their oxidized surfaces . Remarkable observations, conclusions and recognitions are communicated besides comments to the theoretical under- standing. Explanations concerning the importance of the tritium problems at the HTR-application for nuclear process heat utilization follow with a representation of release-rates at the example of the NPW-3000-facility and potential improvement factors. To the range of problems of the tritium removal out of the cooling circuit of HTRs a survey is given about the state of investigation concerning suitable getter-procedures and also data for the application are given. From investigations performed in the Institute of Nuclear Physics of the university of Cracow it is reported about the influence of hydrogen trapping during the transportation process of this gas in metals. Electrochemical permeation measurements on the material Incoloy 800 at room temperature led to the presented results. Finally a survey is given about the pre-coating program of -the partners M.A.N., NUKEM and KFA as well as the critical presentation of the conditions and results of permeation measurements with deuterium model gas mixtures on disk-shaped alloy-samples.
