CIRCONIO BASED ALLOY AND COMPONENT MANUFACTURING PROCEDURE FOR NUCLEAR FUEL SETS OF SUCH ALLOY.

摘要

Application of a zirconium-based alloy that also contains, by weight, in addition to the inevitable impurities, 0.02% to 1% iron, 0.8% to 2.3% niobium, less than 2000 ppm tin, less than 2000 ppm of oxygen, less than 100 ppm of carbon, 5 ppm to 35 ppm of sulfur and 0.01% to 0.25% of chromium and / or vanadium in total, the ratio between Niobium content minus 0.5% to iron content, eventually completed by chromium and / or vanadium content, to the construction of components for a pressurized water reactor that initially contains less than 3.5 ppm of lithium.
