  • Publication number: 20220102017
    Abstract: A fuel assembly, a fuel rod and a cladding tube for a fuel rod for a nuclear reactor are disclosed. The cladding tube includes a tubular substrate defining an inner space for housing nuclear fuel pellets, and a surface layer applied on the tubular substrate. The tubular substrate is made of a zirconium base alloy and has a first thermal expansion coefficient. The surface layer has an alloy which consists of a major part of main elements comprising Cr and at least one of Nb and Fe, a minor part of zirconium, and possibly a residual part of interstitial elements. The alloy of the surface layer has a second thermal expansion coefficient. The concentrations of the main elements are selected so that the second thermal expansion coefficient is greater than the first thermal expansion coefficient from 20 to at least 1300° C.

  • Patent number: 4902445
    Abstract: Fiber boards of high strength which are highly water- and flame-resistant are disclosed, as well as a method for making such boards and an inorganic binder composition for bonding wood fibers. The boards comprise a lignin-containing fiber material, a binder derived from a binder composition comprising an alkali silicate solution, sulphur and/or an inorganic sulphur compound, and a calcium and/or magnesium compound and, optionally, fillers and/or hydrophobing agents.The fiber boards are manufactured by mixing the lignin-containing fiber material with the binder composition and optional further additives, whereupon the mix is compressed at a high pressure and at a temperature of 130.degree.-230.degree. C.

  • Patent number: 4761342
    Abstract: A fibre board having improved strength, water-resistance and flame resistance comprises a lignin-containing fibre material and a binder. The binder is formed from a binder solution containing an alkali silicate solution, a sulphur component, and an metal component. The solution may also include hydro-foaming agents, fillers and other materials. The preferred binder solution includes 50-90 parts by weight alkai silicate solution, 0.5-10 parts by weight sulphur component and 10-40 parts by weight of the metal component. A method is also presented for the formation of an improved fibre board through utilization of a preferred mixture of a lignin-containing fibre material and a preferred binder solution under pressure, at a temperature of about 130.degree. to 230.degree. centigrade.
