Patent number: 6296786Abstract: A treated waste has been treated so as to prevent diffusion of a substance to be disposed, of e.g., radionuclide “I”, that tends to occur when the waste is disposed of in reducing environment at an ultra-deep underground. The treated waste has a low-resolution compound containing “I”, e.g., “AgI”, and a high oxygen potential agent having a higher oxygen potential than the compound, e.g., “Fe2O3”. Ionization of the substance to be disposed, attributable to reduction of the compound, can be suppressed over a long time.Type: GrantFiled: July 28, 1998Date of Patent: October 2, 2001Assignee: Kabushiki Kaisha Kobe Seiko Sho.Inventors: Ryutaro Wada, Tsutomu Nishimura, Tsuyoshi Imakita, Yoshitaka Kurimoto, Yasushi Sugimura

Patent number: 5863505Abstract: The present invention provides an underground-environment simulator which simulates underground environment spaces used for radioactive waste disposal or the like, and has a hermetic box, wherein the carbon dioxide gas concentration inside the box can be adjusted to an optional level, and the atmosphere inside the box can be uniformly and stably maintained. In the underground-environment simulator of the present invention, a carbon dioxide gas feeding means feeds carbon dioxide gas into a circulating gas circulation which controls the atmosphere inside the hermetic box, and the concentration of carbon dioxide gas in the circulating gas is measured and adjusted to a predetermined level while oxygen is removed from the circulating gas in an oxyhydrogen reactor. Accordingly, the carbon dioxide gas concentration can be controlled within a low concentration range, and various underground environments can be accurately simulated by varying the carbon dioxide gas concentration to an optional level.Type: GrantFiled: May 27, 1997Date of Patent: January 26, 1999Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Ryutaro Wada, Makoto Asao, Tsutomu Nishimura, Toshio Iwata, Kenji Yamaguchi, Kiyoshi Tsune
