摘要： PURPOSE:To radiate the heat, generated inside a stator coil, to the outside efficiently by inserting the heat-absorbing side of a heat sink into between laminated iron core blocks, and attaching the heat radiating side to the outside of the laminated iron core block. CONSTITUTION:A stator coil 2 and a heat absorbing fil 11, in close contact with a laminated iron core block 1, are mounted between a laminated iron core block 1 and a laminated iron core block 1. A through hole not shown in the figure is provided in this heat absorbing fin 11, and the heat absorbing part 15 of a heat pipe 10 is inserted into this through hole so as to absorb the heat inside the stator coil 2. On the other hand, the heat radiating part 14 is attached to the outside of an outlet pipe 16 connected to an outer duct 4, whereby heat is transmitted to conductive fluid through the outlet pipe 16. This way, it is so arranged that the heat inside the stator coil 2 may be collected efficiently in the fluid flowing inside the outlet pipe 16 making use of the evaporating and condensing actions of the heat medium inside the heat pipe 10, so heat generation of the stator coil can be enlarged, whereby a small- sized and large capacity of electromagnetic pump can be obtained.

摘要： PURPOSE:To efficiently radiate the heat generated by a coil section to the outside by providing iron core keeping plates or plate springs incorporating springs to iron core guides installed to a casing in corresponding to each laminated iron core block. CONSTITUTION:Laminated iron core blocks 1 are arranged at nearly regular intervals in the circumferential direction in a casing 9 and, in each block 1, numerous coils 2 are arranged in the axial direction and outer and inner ducts 4 and 5 forming an annular flow passage 3 are arranged in a double circumferential duct structure. In addition, iron core guides 12 are provided in the casing 9 at every block 1 and iron core keeping plates 13 are arranged at nearly regular intervals in the longitudinal direction in the grooves of the guides 12. Therefore, the heat generated by the coils 2 can be efficiently radiated to the outside and the temperature rise of the coils 2 can be suppressed, since the blocks 1 can be always press-contacted with the outer ducts 4 by means of the plates 13.

摘要： PURPOSE:To make construction works much easier and to reduce an amount of required materials and to save a cost by coating floors in a nuclear reactor auxiliary building with a heat resistant and sodium resistant painting material. CONSTITUTION:On a surface of a floor concrete 31 of a nuclear reactor auxiliary building 5, a heat resistant and sodium resistant painting material 32 of which main component is at least one of Al2O3, MgO, ZrO2, SiO2 and SiC, is applied in a constant thickness and thereafter a water content is removed by heating. With this process, a sodium leaked in the building 5 is collected to a lower place by an incline provided on the floor surface and then is stored at a storage pit prepared at the lower-most part of the building 5, through a drain pipe 33. Accordingly, there is no requirement to place a steel liner on the floor surface of the building 5, where a piping and an equipment of a secondary sodium circulation system are installed, construction works can be much easily conducted and also as there is no requirement to apply a sliding structure for a prevention of a liner deformation, an amount of required materials and construction cost can be well saved.

摘要： PURPOSE:To obtain a detecting system having high reliability by admitting a gas which does not contain sodium through a flow control valve into the detecting system, closing all the valves provided to sampling pipings, to decrease and stabilize the output of a detector then opening and closing successively the valves and checking the leaking piping. CONSTITUTION:A valve 14 is opened to admit the gas which does not contain sodium through the flow control nozzle 13 into a header 11 and all the valves 6 are closed when the sodium leak is detected by the rise of the output generated by the sodium introduced to the sodium leak detector 7 through the sampling pipings (A-D)5, the header 11 and confluent piping 12. The flow rate from the nozzle 13 is so adjusted as to be decreased by as much as the flow rate of one sampling piping from the amt. of the gas admitted through all the pipings 5. As a result the output of the detector 7 decreases and stabilizes, and when the output equivalent to the output of the case in which no leakage is generated is attained, the valves 6 are successively opened and closed. The corresponding piping 5 is determined as the leaking piping when the output of the detector 7 increases again and the output approximately equal to the output obtd. in the stage when the leak is detected is confirmed as a result of such valve opening and closing.

摘要： PURPOSE:To obtain the sampling instrument for liquid metal which has no leak- in of oxygen and high reliability and eliminates the need to consider a countermeasure to a high vacuum by blowing inert gas which contains a small amount of heated liquid metal to a sampling pot. CONSTITUTION:The inert gas flows in a vapor trap from a pipe 34 for suction and is cooled to remove the liquid metal, and then the cooled inert gas is passed through a pipe 33 and heated by a heater 28 up to its distillation temperature. Then, the inert gas which is heated at high temperature and contains a small amount of liquid metal is passed through a pipe 35 and a tee 37 and blown to the sampling pot to return into a container 1. This natural convection vaporizes the liquid metal in the sampling pot 4 efficiently and the metal is trapped by the mesh part of the vapor track 8. The heater 28 and preheaters 23-27, and 39 are stopped to cool the sampling pot 4, and the flange 3 is detached from an outlet and the sampling pot 4 is removed to take an atomic absorption analysis of the sodium oxide in the pot 4, measuring the amount of oxygen.
