摘要： PROBLEM TO BE SOLVED: To provide a membrane filtration module for detecting a functional deterioration of a filtration membrane which is capable of measuring the properties of a water filtrate as a water to be tested in situ without changing the properties of a water filtrate and does not need a lot of steps of sensor construction works at the time of exchange of a membrane filtration module and to provide a membrane filtration operating device.
SOLUTION: The membrane filtration module is provided with a communication device by incorporating a sensor device into a filtration water discharge port of a case housing of a membrane filtration module. Thus, the properties of the filtration water can be measured. If the membrane filtration module is exchanged using, for example, ad hoc communication, the adjustment of the communication system is not needed anew. Although passage light of the filtration filter is set to a certain level because the capture of an impurity material is little when there is no leak from the filtration membrane, the passage light is reduced because the impurity material that leaks into the filtration water can be captured by the filtration filter and light is shaded by the captured impurity material of the filtration filter. The leak due to the filtration membrane failure can be detected and the failure is detected.

摘要： PURPOSE:To avoid stress concentration between layers and improve anti-PCT and anti-corrosion capabilities by using such single layer cladding that weight percentage main component metal is high at the inner surface and low at the outer surface and the weight percentage of additive element is low at the inner surface outer surface. CONSTITUTION:In a fuel cladding tube 1, a plurality of sintered fuel pellets 2 formed by compaction are charged and a plenum spring is put on the top end and both ends are sealed by welding end plugs 4. The weight fraction of zirconium in the cladding is 99.5% at the inner surface and is decreased toward the outer surface. On the contrary, the content of alloy elements, Sn, Fe, Ni and Cr are increased toward the outer surface to be ca. 1.5% of Sn, 0.16% of Fe, 0.06% of Ni and 0.1% of Cr. On the outer surface, oxide coat is formed. By this, stress concentration between layers is avoided, the interaction with pellets 2 is mitigated at the inner surface by the high content zirconium and corrosion due to contact with water is prevented at the outer surface.

摘要： PURPOSE:To facilitate discharge of non-condensible gas for disturbing heat transfer in an absorber for an absorption refrigerator and to reduce pressure loss. CONSTITUTION:Vapor 4 generated from an evaporator is fed from above a tube group 11, spread to an entire absorber through a vapor passage 12, and absorbed to absorbent liquid scattered from an absorbent scattering unit 7 to outer surfaces of heat transfer tubes. A vapor fluidizing resistance can be reduced by an effect of the vapor passage 12. Non-condensible gas is discharged in a high efficiency by so straightening it by a vapor straightener 5 disposed on the passage 12 that a final arrival point of a vapor flow becomes a bleed port 10 to be used also as an absorption discharge port.

摘要： PURPOSE:To reduce a flowing resistance of vapor in an absorber device in an absorption refrigerator machine and to facilitate a discharging of non- condensed gas at the absorber device. CONSTITUTION:Vapor generated at an evaporator passes through a vapor flowing-in part 3 and further passes through a vapor flow passage 2 to occupy an entire interior part of an absorbing device. In concurrent with this operation, the vapor is absorbed by the absorbing liquid 5 dispersed from an absorbing liquid dispersion device 4 to an outer surface of each of heat transfer pipes. Flowing resistance of vapor can be reduced under an effect of the vapor flow passage 2 between a region of pipe groups of heat transfer pipes 1 closely arranged to each other and the wall surface. In addition, the vapor flow is regulated by a vapor flow regulator plate 9 arranged in the vapor flow passage 2 in such a way as a final reaching point of the vapor flow becomes a vapor extracting port 6 also acting as an absorption liquid discharging port or a gas extracting port 7.

摘要： PURPOSE:To provide diagnosis with high reliability by performing the diagnosis based on the detection outputs of the state and nature of apparatuses constituting fluid circulation facilities. CONSTITUTION:In the circulation line of the circulation facility 1 of an atomic power plant, for example, the steam boiled from the pure water by a reactor core 61 in an atomic reactor 60 is liquefied by a condenser 68 after driving a turbine 67, it is converted into the pure water by a condensate demineralizer 69, then it is preheated by a water feed heater 69 then returned to the atomic reactor 60 by a water feed line 64. The pure water is returned to the atomic reactor 60 by a re-circulation system 62, and the purified 63 pure water is guided to the line 64. The vibration of the re- circulation system 62 is detected by a vibration detecting device provided on the facility 1 as the vibration of the facility apparatus itself then analyzed and inputted to an abnormality judging device 2. The stuck particulate materials are peeled off by the abnormal vibration, the circulation water with the increased number of particulate materials is detected 72 by a particulate material counting device 22 via a sampling line 9, signal-processed 73, and inputted to the device 2. The device 2 judges an abnormality based on the threshold value level from fluctuation values.
