摘要： PROBLEM TO BE SOLVED: To keep a clevis between the heat transfer pipe and support plate of a steam generator in non-corrosive atmosphere by measuring SO4 concentration of water in the steam generator in the operation of a pressurized water reactor, and adding calcium Ca or magnesium Mg to neutralize SO4 when it exceeds a prescribed threshold. SOLUTION: Chemical components which fluctuate clevis internal pH include sodium Na, potassium K, sulfur tetraoxide, and sulfuric ion SO4 , and the influence of sulfur tetraoxide is particularly large. Thus, when the influence of sulfur tetraoxide is reduced, the clevis internal pH can be kept near neutral area. When the cation concentration is raised to set total cation (c)/SO4 mole ratio to 1 or more, the clevis internal pH is transferred to neutral or weak alkaline side. As cation species, calcium and/or magnesium are added. Calcium hydroxide or magnesium hydroxide is added to the bulk water of the steam generator in an extremely trace amount up to several ppb, whereby the clevis internal pH situated on acidic side can be moved to neutral area.

摘要： PROBLEM TO BE SOLVED: To inhibit the damage to heat-transfer pipes by sampling feedwater and measuring the molar ratio of all cations to SO4 to keep it within a proper range. SOLUTION: When the relation between the molar ratio of the bulk water in a steam generator and the atmosphere (pH) in a dummy clevis part is measured by using a testing device, a good correlation is recognized in a wide range from a low pH to a high pH between the molar ratio of all cations (ΣC) to SO4 of the bulk water and the pH in the dummy clevis part. The environment in a clevis part can be presumed from the water quality of the bulk water in the steam generator during the operation of it. The measurement of the molar ratio of all cations (ΣC) to SO4 of the bulk water in the steam generator from such a correlation makes it possible to presume the environment or the pH in usually inaccessible narrow interstices between the outer faces of heat-transfer pipes and support plates in the steam generator. If the steam generator is operated so as to keep the pH between pH5 and 8, within the neutral range, the corrosion cracking of the heat-transfer pipes can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a method of removing scale stuck to the outer part of a heat transfer tube while maintaining the heat transfer performance of a steam generator used in a nuclear power plant, to a high level.
SOLUTION: The surface of the heat transfer tube is smooth in an initial state A, and the surface area is minimum. When the steam generator is operated, scale sticks dispersedly to the surface of the heat transfer tube, and the scale becomes a core of boiling, so that the heat transfer performance of the steam generator gradually rises. Upon reaching B, however, holes in the scale surface are filled, and the scale grows in rough and fine layers. In this process, the surface area is approximately constant, but thermal resistance increases with the increase of scale thickness, and the heat transfer performance of the steam generator falls. The heat transfer performance of the steam generator can be maintained to the high level by removing a part of the scale formed on the outer surface of the heat transfer tube of the steam generator by washing to increase the surface area.

解决方案：传热管的表面在初始状态A下平滑，表面积最小。蒸汽发生器运行时，分散放置在传热管表面，鳞片成为沸腾的核心，蒸汽发生器的传热性能逐渐上升。然而，到达B时，刻度表面上的孔被填充，并且刻度在粗糙和细小的层中生长。在该过程中，表面积近似恒定，但随着氧化皮厚度的增加热阻增加，蒸汽发生器的传热性能下降。蒸汽发生器的传热性能可以通过洗涤来除去形成在蒸汽发生器的传热管的外表面上的一部分刻度，以增加表面积，从而保持高水平。版权所有（C）2007，JPO＆INPIT
