Patent number: 6800196Abstract: Radioactive laundry liquid wastes are supplied in a liquid waste heating vessel. Hydrogen peroxide and an alkali solution are supplied to the liquid waste heating vessel. The pH of the radioactive laundry liquid wastes is adjusted to 7 or higher by the alkali solution. The radioactive laundry liquid wastes are heated to 50° C. or higher by a heating device and introduced to first and second aeration vessels. The temperature is controlled by a device in accordance with the value measured by a thermometer. Ozone is supplied from an ozone generator by way of an ozone gas discharge port to the first aeration vessel. Ozone discharged from the first aeration vessel is introduced from the ozone gas discharge port to the second aeration vessel. Therefore, the amount of ozone dissolved into the radioactive laundry liquid wastes is increased so that the amount of hydroxy radicals formed for decomposing organic substances increases, since the laundry liquid wastes are heated to 50° C.Type: GrantFiled: December 28, 2001Date of Patent: October 5, 2004Inventors: Toshiaki Matsuo, Takashi Nishi, Takayuki Matsumoto, Masami Matsuda, Atsushi Yukita

Patent number: 6502520Abstract: An incineration and melting furnace has a furnace main body that is filled with a conductive heat generation body (for example, graphite). Radioactive combustible materials in contact with the conductive heat generation body are burnt and the radiaoactive incombustible materials are melted. The resultant exhaust gases and the molten products flow downwardly in the conductive heat generation body filled region and flow out of a molten product discharging port. Noxious gases such as dioxins contained in the exhaust gases are thermally decomposed into a non-toxic state in a high temperature portion of the conductive heat generation region.Type: GrantFiled: July 13, 2000Date of Patent: January 7, 2003Assignee: Hitachi, Ltd.Inventors: Takashi Nishi, Hideo Hashida, Toshiaki Matsuo, Takeyuki Kondo, Masami Matsuda, Kiyotaka Ueda

Patent number: 5498828Abstract: An object of the present invention is to improve retainability (distribution coefficient) for C-14 of a radioactive waste solidified body. The waste is solidified with a solidification agent containing a soluble substance which yields an insoluble substance by a reaction with carbonic ions, insoluble carbonates, or a mixture of the above substances.

Patent number: 4636335Abstract: A method for processing spent radioactive ion exchange resin formed in a nuclear power plant by a two-step pyrolysis method. First, the spent resin is heated at 350.degree. C. to decompose functional groups selectively. Then the base polymer, formed as residue, is decomposed at a temperature above 350.degree. C., e.g. 600.degree. C. After the thermal decomposition, exhaust gases which require a special exhaust gas disposal means, such as NO.sub.x and SO.sub.x can be reduce to below 1/20.Type: GrantFiled: December 7, 1983Date of Patent: January 13, 1987Assignee: Hitachi, Ltd.Inventors: Fumio Kawamura, Masami Matsuda, Yoshiyuki Aoyama, Koichi Chino, Mamoru Mizumoto

Patent number: 4628837Abstract: In a method of processing radioactive spent ion exchange resin, the spent ion exchange resin is pyrolyzed in an inert atmosphere and harmful decomposition gas such as sulfur and nitrogen compounds generated during pyrolysis is separated. Next, the spent ion exchange resin is pyrolyzed in oxidizing atmosphere and harmless gases such as carbon dioxide and water vapor gases are separated. It is preferred that a transition metal as a catalyst be adsorbed through ion exchange into spent cation exchange resin, and an anionic atom group containing a transition metal as a catalyst be adsorbed through ion exchange into spent anion exchange, before both of the pyrolysis steps. The pyrolysis is carried out at two atmosphere stages, and the harmful and harmless gases are decomposed separately. The pyrolysis in both of pyrolysis steps is effected at a temperature in the range of from 240.degree. to 420.degree.

Patent number: 4424016Abstract: A granulating apparatus comprising a device which adds a binder of an epoxy resin or the like into a powder to-be-treated, a screw feeder which conveys the powder to-be-treated containing the binder, and rolls which compression-molds it. By rotating the screw feeder and the rolls, the powder to-be-treated is caused to induce internal friction and to generate heat, thereby to temporarily dissolve the binder, whereupon the powder to-be-treated is pelletized. In order to temporarily dissolve the binder, the granulating apparatus is equipped with a device for measuring the temperature of the powder to-be-treated, and a controller for controlling the stirring speed of the screw feeder and the molding speed of the rolls on the basis of the measured value so as to establish a desired temperature.Type: GrantFiled: December 22, 1981Date of Patent: January 3, 1984Assignee: Hitachi, Ltd.Inventors: Masami Matsuda, Koichi Chino, Kazuhiko Kudo
