    摘要: A method for solidifying a radioactive iodine-containing waste, in which volatilization of radioactive iodine outward can be suppressed during solidification, and a solidified waste having a high level of confinement of radioactive iodine and a long term stability can be obtained. The method comprised mixing a granular waste containing radioactive iodine, e.g. a granular iodine adsorbent having radioactive iodine adsorbed and collected thereon, with a metal powder, e.g. a copper powder, having a corrosion resistance in an environment of solidified waste disposal, filling the resulting mixture in a metal capsule, and subjecting the whole to hot isostatic pressing to effect solidification. In the resulting solidified waste, particles of the radioactive iodine-containing adsorbents are dispersed and retained in the sintered matrix of the metal powder formed through the isostatic pressing.

    摘要: A nickel alloy having an excellent corrosion resistance (hereinafter referred to as “nickel alloy”) used for pipes, structural materials and structural members, such as bolts or the like, in a nuclear power plant or in a chemical plant, and a manufacturing method for the same are provided. In the nickel alloy according to the present invention, an excellent corrosion resistance, in particular an excellent resistance against the IGSCC, is obtained by specifying the low angle boundary rate of 4% or more in the grain boundaries, along with the restriction of the chemical composition in the alloy, thereby making it possible to provide a nickel alloy which is most suitably used for pipes, structural materials and structural members, such as bolts or the like. Accordingly, the nickel alloy according to the present invention is widely applicable to structural members used in a nuclear station or in a chemical plant.

    摘要: A method for manufacturing a Ni-based alloy article which elutes little Ni even when used in a high-temperature water environment for a long period comprises heating the Ni-based alloy in a carbon dioxide-containing atmosphere for a set period of time at an elevated temperature to form an oxide film comprising chromium oxide on a surface thereof. Using carbon dioxide as an oxidizing gas produces an oxide film of generally uniform thickness along a length of the article being treated so that resistance to nickel elution is more uniform over the entire article.
