摘要： Granular ion exchange resins in a desalter provided in a nuclear power plant are taken out from the desalter as used ion exchange resins when their capacities are lowered. The used ion exchange resins in a slurry state are led to a thin film drier. A rotating shaft provided with rotating blades is inserted in the thin film drier. When the slurry of the used ion exchange resins is led thereto, the rotating shaft is driven to rotate, and the side wall of the thin film drier is heated. The used ion exchange resins led to the thin film drier are heated and pulverized to powder by the action of rotating blades. The powder is taken out of the thin film drier to the outside and shaped into pellets.

摘要： A radioactive waste is treated by supplying a liquid concentrate of at least one of a radioactive liquid waste and a radioactive waste slurry to a centrifugal film dryer, thereby drying and pulverizing insoluble and soluble solid matters contained in the concentrate, washing the centrifugal film drier with hot water after the drying and pulverization, settling the effluent washing water together with a condensate containing solid matters generated in the drying and pulverization, and supplying a slurry of insoluble solid matters separated by the settling to the centrifugal film drier, thereby drying and pulverizing the solid matters. The dried powder from the centrifugal film drier can be pelletized in a pelletizer, and effluent washing water generated by washing the pelletizer with hot water after the pelletization can be subjected to the settling together with the effluent washing water and the condensate from the centrifugal film drier. Operating load of the centrifugal film drier is considerably reduced, and the operating efficiency and life of the centrifugal film drier are improved thereby.

摘要： Provided is a method of producing radio-active waste package. By evaporating and drying, the radio-active waste is reduced to a radio-active powder which is formed into pellets in order to ease its disposal. The pellets are received in a container and then impregnated therein with a thermoplastic composition so as to be integrally solidify in the container. The prior technical method cannot fully impregnate the pellets with the thermoplastic material. The present invention improves the prior art technical method of producing radio-active waste package thereby to eliminate the above disadvantage. The present invention also provides a device for carrying out the above method.

摘要： In treatment of aqueous solutions and suspensions of radioactive waste through a step of drying and pulverizing the aqueous solutions and suspensions and a successive step of compressing and solidifying the resulting powders of radioactive waste, a step of measuring a water content of the powders is provided between the step of drying and pulverizing and the step of compressing and solidifying. When the measured water content of the powders fails to satisfy a predetermined water content, the powders are eliminated from a system of the treatment without passing through the step of compressing and solidifying.

摘要： A hydrogen generating apparatus has, at least, a material gas supply system, steam generator, an air supply system, a reforming system including a reformer and a shift converter each incorporating a catalyst, a product hydrogen transporting system, and a reformer combustion gas exhaust system. The apparatus is characterized by further having a shift converter jacket surrounding the catalyst of said shift converter, a branch pipe branching from said reformer combustion gas exhaust system and leading to said shift converter jacket, and a change-over valve provided at a portion of said reformer combustion gas exhaust system where said branch pipes branches off said reformer combustion gas exhaust system. During the start-up of the apparatus, the combustion gas exhausted from the reformer is introduced into the shift converter jacket to heat the shift converter thereby realizing a quick start-up, i.e., temperature rise, of the reformer system.

摘要： A rotary vane type evaporator has a cylindrical vessel and a rotor rotatable therein. The rotor has vane supports fixed to a rotor shaft and vanes each pivotally mounted at the radially inner end to a vane support and having a radially outer end connected with a shoe extending in the circumferential direction of the vessel. Each vane is provided with a balance weight acting to keep constant, irrespective of the wear of the shoe, the pressing force which urges the shoe against the vessel inner peripheral surface. The rotor vanes are disposed in a plurality of stages arranged in axial direction of the rotor. The rotor is so constructed as to uniformalize the wear of the vane shoes over all the stages, whereby the frequency of the interruption of the evaporator operation for the renewal of vanes is lowered to improve the rate of the operation of the evaporator.

摘要： An aqueous solution containing granular ion exchange resin and filter aid as a radioactive waste generated from a nuclear power plant is supplied to the casing of a centrifugal film dryer, which comprises a casing, a rotating shaft inserted in the casing, rotating blades fixed to the rotating shaft within the casing, and a heating means for heating the wall surface of the casing. The aqueous solution flows down along the heated inside wall of the casing while the rotating shaft is rotated. Water of the aqueous solution is evaporated, while the granular ion exchange resin and the filter aid are turned into powder by the action of rotating blades in rotation. The powder is led to a pelletizer, and shaped into pellets. The pellets are filled in a drum, and asphalt is then filled in the drum. After the solidification of the asphalt, the drum is tightly sealed.
