摘要： PURPOSE:To make it possible to measure the wide region in a waste body accurately and quickly by pushing the surface of the waste body at the approximately continuous line or plane which surrounds the vicinities of transmitting units and receiving units. CONSTITUTION:An apparatus for measuring an ultrasonic-wave propagating speed and computing compressive strength is provided with the following parts: a plurality of ultrasonic wave piezoelectric transducers which transmit or receive ultrasonic waves; a pushing means 4 for a transmitting/receiving unit which pushes the piezoelectric transducer 1 on the surface of a waste body 3; and a surrounding pushing member 5 which pushes the surface of the waste body 3 at the approximately continuous line or plane which surrounds the vicinity of each piezoelectric transducer 1. The means 4 has a piston/cylinder mechanism for pushing the piezoelectric transducer 1 to the waste body 3. The means 4 is fixed to a frame 8 as a unitary body together with the piezoelectric transducer 1. In this way, adhesion of the piezoelectric transducer 1 to the waste body 3 is enhanced with the means 4 and the member 5. Therefore the surface waves are extremely eliminated, and only the transmitting waves which reflect the compressive strength of the waste body 3 correctly are excellently trans ferred to to the waste body 3 and detected.

摘要： PURPOSE:To efficiently perform cleaning by means of an reverse air flow and to make it possible to design an apparatus which is long in the direction of the length of hollow fibers, by superposing a plurality of hollow fiber membrane filter modules on each other into a unit, and connecting openings of modules of the second and subsequent stages with an opening of the first stage module by means of a water-collecting tube. CONSTITUTION:A large number of hollow fiber membranes 11, 21 are bundled, and one end 12, 22 of each bundle is fixed to prepare hollow fiber membrane filter modules 1, 2. At least two such modules are superposed on each other and united, and an opening 23 of the second stage module 2 and an opening of any subsequent stage are connected with an opening 13 of the first stage module by means of a water-collecting tube 4, thereby allowing the module of each stage to be open to a filtrate chamber. Thus, the filtrates obtained through the modules of the second and subsequent stages are let into the filtrate chamber by the water-collecting tube 4. Accordingly, the apparent effective length of the module unit can be increased, with the effective length of the hollow fiber membranes per se being not changed.

摘要： PROBLEM TO BE SOLVED: To facilitate transportation, treatment and the evaluation of radiation of solidified matters, and reduce the equipment cost by performing dewatering process directly and continuously for the generating spent resin beads and resin powder. SOLUTION: Radioactive spent ion exchanger resin beads and powder generated from a condensate demineralizer and a filter demineralizer of a reactor power plant are collected from each receiver tank 7 into a spent resin supply tank 4. According to the treatment capability of a dewatering machine 5, the resin beads and powder are continuously transported from the tank 4 to the dewatering machine 5 to be dewatering treatment. The obtained dewatered resin beads and powder is solidified by a cement solidification directly or afterward a temporal storage, or after incineration treatment, and the burned ash is solidified by cement solidification. Thus, take-out from tanks and troubles in transportation are resolved and treatment is made easy. Also, as the treatment is made immediately after generation, the evaluation of radioactivity is made easy. As large tanks for storage is unnecessary, the facility cost can be drastically reduced.

摘要： PURPOSE:To simplify the structure of a filter apparatus, by mixed-arranging hollow fibers which have a specific pore size and are used for air-backwashing, with the hollow fibers in the prescribed ratio based on the total numbers of the hollow fibers, thereby enabling the air-backwashing, without applying to air-scrubbing. CONSTITUTION:The hollow films for filter which are composed of polysulfone, etc., and have the pore size of 0.03-0.5mum, and the hollow fibers for air- backwashing which are composed of a cross-linked polyvinyl alcohol, etc., and have the pore size of 0.5-1mum are used for the titled module, and the hollow fibers 3 for the air-backwashing are uniformely distributed throughout the hollow fibers 2 for the filter so as to be 1-10% the total numbers of the hollow fibers. The titled module is constituted by the hollow fibers as mentioned above, together with a protective column 4. The air-backwashing of the filter apparatus used for the titled module 1, is effectively carried out by feeding air to said filter apparatus under pressure from an outlet side of a module filtrate, and then discharging, whereby the air fed under the pressure is discharged into a liquid from the hollow fiber 3 for the air-backwashing and forms bubbles, and then forms a liquid trap by rising in the liquid.
