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.
