  • Component designed for use in a light water reactor, and a method for the manufacture of such a component
    Patent number: 6512806
    Abstract: A component (1) designed for use in a light water reactor and at least partly comprised by a metal and/or a metal alloy presents a coatings (4, 7) at its outer surface (3) and its inner surface(5). The coating (4 and 7 respectively) has as its task to protect the surface (3 and 5 respectively), against oxidation, corrosion, wear and hydration. The coating (4 and 7 respectively) suitably comprises at least one of zirconium dioxide (ZrO2) and zirconium nitride (ZrN).

  • Nuclear fuel element for pressurized-water reactors
    Patent number: 5901193
    Abstract: The 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.degree. C.

  • Zirconium-based alloy for components in nuclear reactors
    Patent number: 5334345
    Abstract: A zirconium-based alloy for components in nuclear reactors with excellent resistance both to corrosion by water and water steam and to hydrogen absorption under operating conditions consists of 1.0-2.0 per cent by weight tin, 0.07-0.70 per cent by weight iron, 0.05-0.15 per cent by weight chromium, 0.16-0.40 per cent by weight nickel, 0,015-0.30, preferably 0,015-0.20 per cent by weight niobium, 0.002-0.05, preferably 0.015-0.05 per cent by weight silicon, 0.09-0.20, preferably 0.09-0.16 per cent by weight oxygen, the balance being zirconium and impurities, normally occurring in reactor grade sponge zirconium, of other kinds than the above-mentioned substances.
