摘要： PURPOSE:To detect the defect in a painted film nondestructively and readily, by periodically emitting light to the painted film, and detecting elastic waves generated on the film. CONSTITUTION:The light emitted from a xenon lamp 24 is intermittently projected on a measuring cell 16 by way of a condenser lens 12, an interference filter 26, and a light chopper 28. Elastic waves generated by the expansion and contraction of a painted film are detected by a microphone 34 and inputted to a lock in amplifier 20. The input signal from the microphone 34 is turned with the signal from a photocoupler 36, which is synchronized with the light chopper 28, and amplified by the amplifier 20. The result is displayed on a recorder 22. Thus the defects in the painted film are readily detected nondestructively.

摘要： PROBLEM TO BE SOLVED: To provide a water quality control system which makes effective use of the information of sensors to control the corrosive environment of a nuclear reactor. SOLUTION: A specific and universal water-quality factor in a specific part is regarded as a reference index, and the concentration of a water-quality softening agent is controlled so that the index can fall within the target range. For this purpose, all sensor groups placed in a primary reactor cooling system are divided in terms of lines whose piping places are different from each other, and a specific sensor group (standard sensor group) is connected to an arithmetic unit 6 and a database 7 to be used as a full-time monitor for the operation and projection of the reference index. Attention is paid only to an oxidizing component in the water at a measurement point, and a concentration distribution agreeing with an actual measurement of the oxidizing component is extracted and adopted as a correct concentration distribution. As a result, the fact that the control index is a universal quantity minimizes the change of the control logic even if changes occur in types and capabilities of sensors or references themselves, and the independence of a single sensor output allows us to expect the maintenance of high accuracy in the system.

摘要： PURPOSE:To indicate the crevice corrosion of structural materials in an early time by providing the anode and cathode of the same material as that of the structural materials in an actual environment in which the structural materials are placed and measuring the crevice corrosion current generated between the anode and the cathode. CONSTITUTION:A protecting body 40 made of a heat-resistant resin is mounted to a flange 38 for mounting detectors by means of pressure sealing jigs 42, 44 and a corrosion sample 46 of the same materials as that of a structural material which serves as the anode is inserted into this body 40, and a clearance 48 is formed between the body 40 and the sample 46. A flat plate counter electrode 50 of the same material as that of the corrosion sample is mounted, too, to the flange 38. The flange 38 is mounted to a part of the plant structural material and the corrosion sample 46 and the counter electrode 50 are exposed to the corrosive environment of actual machines. The structure equivalent to that of the clearances of the structural material is given by the clearance 48, and therefore if crevice corrosion occurs in the sample 46, electrochemical reaction takes place between the sample 46 and the electrode 50, and the current corresponding to the rate of corrosion flows in a nonresistance ammeter 56.

摘要： PURPOSE:To effectively prevent the atmospheric corrosion of a stainless steel product under an environment easy to adhere a marine salt particle, by controlling the relative humidity or less of an atmosphere to limit relative humidity of atmospheric corrosion inherent to a corrosive substance. CONSTITUTION:The relative humidity of the atmosphere contacted with the surface of a stainless steel product used in the seashore is controlled so as to reach limit relative humidity or less of atmospheric corrosion inherent to a corrosive substance such as a marine salt particle adhered to the surface of said product. This control of relative humidity is performed by dehumidifying the atmosphere contacted with the surface of the stainless steel product and raising and falling said product or raising the surface temp. of the product. By this control of the atmosphere, the corrosion trouble of the stainless steel product or structure constructed in the vicinity of the seashore can be prevented and the enhancement in the safety and operation efficiency of a plant is achieved.

摘要： PURPOSE:To measure little amount of liquid like 5mul under atmospher by reading an initial value immediately after a sample liquid is injected into an electric conductivity cell. CONSTITUTION:An electric conductivity cell is constituted by arraying two electrodes having a 0.3mm. diameter in an insulating cylinder having 1mm. internal diameter and 7mm. length in parallel in the lengthwise direction of the insulating cylinder. This cell is placed under the atmospher and an about 5mul amount of sample liquid is injected; although the electric conductivity is zero while the cell is not filled with the liquid, the electric conductivity increases rapidly simultaneously with the start of the injection of the liquid into the cell. After the cell is filled with the liquid, namely, at a point A of time, the indication value of the electronic conductivity rises and then falls slowly because of the dissolution of atmospheric impurities into the liquid and the evaportion of the liquid. For this purpose, the value at the point A of time is read to measure the electric conductivity of small amount of sample liquid sufficiently.

摘要： PURPOSE:To make possible the measurement of high accuracy for a long period of time by absorving the change in the volume of electrolyte by the movement of a piston in a passage. CONSTITUTION:Pure water 16 is filled in a pressure vessel and the material to be examined is immersed therein, thence the vessel is hermetically sealed. When this pressure vessel is raised of temp., electrolyte 2 is heated as well. Hence, the volume of the electrolyte 2 expands, but the increased component of the volume forces down the piston 7 in a passage 6 and the piston stops where the pressure of the pure water 16 and the pressure of the electrolyte 2 balance. Next, when the temp. of the pure water 16 is lowered, the piston 7 ascends in the passage, and moves to where the pressures of the electrolyte 2 and the pure water 16 balance. Namely, the volume change by the temp. change of the electrolyte 2 is absorbed by the movement of the piston 7. Hence, a liquid path part 4 is in the state that it is always impregnated with the electrolyte 2, thus the characteristics which are good over a long period of time is maintained.

摘要： PURPOSE:To prevent stress, corrosion and crack of the reactor, by adding Li OH to the primary cooling water, with lithium (Li ) type ion exchange resin applied to a desalter of reactor clean system, to keep the primary cooling water in alkaline state of pH8 to 10. CONSTITUTION:For a pH tempering compound of primary cooling water in the boiling light-water reactor, for instance, LiOH, NaOH, KOH, etc. will be used. The cooling water is always exposed to a strong radiation. As a material, with addition agent not secondaryly activated, not seized by a desalting device in the core clean system to purify a slight amount of impurities with the core made partially bypassing, and relatively easy to be procurable, the most suitable is Li OH. Li , with a secondary activity not charged, by using lithium type (Li ) ion exchange resin to the core clean system desalting device, because of no consumption of Li OH in the cooling water, will be suitable for pH tempering alkaline compound.
