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.

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.
