Twin hopping in nanolayered zr-2.5nb
WebZr-2,5 % Nb alloy are widely used as structural material for pressure tubes of channel nuclear power reactors with heavy pressured water (CANDU-PHW) and boiler water (RBMK, Fugen). Tensile and creep behavior of Zr-2,5 % Nb alloy significantly depend on heat treatment. To satisfy design requirements to reactor pressure tubes Zr-2,5 % Nb WebZr-2.5Nb (Grade R60904) is a binary alloy with niobium to increase the strength. The alloy has been utilized for pressure tubes in CANDU reactors. Advantages of zirconium alloys for long term nuclear waste disposal
