Special Issue Information
Dear Colleagues,
This Special Issue aims to cover the recent progress and trends in both theoretical and experimental results related to hydrogen isotope permeation reduction and retention in order to develop advanced materials. A better understanding of hydrogen diffusivity, solubility, and permeation is important to reduce hydrogen ingress and build-up, which could cause issues related to embrittlement in structural materials and the leakage of tritium into the reactor coolant. Many material properties impact the hydrogen transport mechanisms, including material phase composition, impurities, grain boundaries, crystal orientation, trapping, defects, and dislocations. Hydrogen isotopes can easily permeate structural materials, which can be detrimental; thus, it is crucial to apply tritium permeation barriers (TRBs) in nuclear reactors to prevent ingress. Hydrogen barriers and accident-tolerant fuel (ATF) cladding materials are crucial to enable safe energy solutions in support of a hydrogen infrastructure, for the safe operation of nuclear reactors such as fusion reactors, for the development of future Gen IV nuclear reactors, as well as to contain spent fuel. With advanced materials, accidents can be avoided or reduced in severity by preventing tank, structural, or pipe-line material failure. On the other hand, membranes that require high permeability are used for purification and gas separation. We invite articles or reviews that cover both applied and fundamental research topics, including the use of computational screening, that demonstrate recent advances in understanding hydrogen permeability. Theories and experiments that are carried out to select materials with reduced permeation, increased permeation retention, or increased permeability may be utilized.
