FIELD: chemistry.
SUBSTANCE: cladding of the fuel element of nuclear reactor contains a substrate containing an inner layer based on zirconium and one intermediate layer located on the inner layer and comprising at least one intermediate material selected from tantalum, molybdenum, tungsten, vanadium, hafnium or alloys thereof, and at least one external layer located on the substrate and comprising a protective material selected from chromium or alloy based on chromium. There is also a method for producing a cladding, use of the cladding, as well as an application for preventing hydrogenation.
EFFECT: improved resistance to oxidation and hydrogenation at very high temperatures to obtain an additional safety margin.
