PCT No. PCT/SE95/01003 Sec. 371 Date May 13, 1997 Sec. 102(e) Date May 13, 1997 PCT Filed Sep. 7, 1995 PCT Pub. No. WO96/07764 PCT Pub. Date Mar. 14, 1996The invention relates to a nuclear fuel element for pressurized-water reactors comprising a fuel cladding of a zirconium alloy composed of two parts. The inner part constitutes a supporting part of a conventional zirconium and the outer part a corrosion-resistant layer of zirconium with 0.65-0.95% Sn and 0.4-0.5% Fe. The difference in Sn content between the inner and outer parts must not exceed 0.7%. The cladding is finally heat-treated within the range 450 to 510 DEG C.
