Abstract
The paper gives analysis of literature data on searching for getter materials, which can be recommended for creation of hydrogen traps by introducing them into structural materials and welded joints of NPP equipment. Hydride-forming alloys and compounds based on zirconium, titanium and vanadium are considered as the most promising ones. Rare-earth metals and their alloys, binary compounds of rare-earth metals with transition metals of VIII group are proposed as materials of getter additives to create hydrogen traps in structural materials and welded joints of NPP equipment.
