Description
本発明の目的は、上述の事情を考慮してなされたものであり、環境等に影響のある薬剤を注入することなく、配管等の構造材の腐食を確実に抑制できるプラントの運転方法及びシステムを提供することにある。
図1は、本発明に係る加圧水型原子力プラントの二次系運転方法における第1の実施の形態が適用された加圧水型原子力発電プラントの二次系を示す系統概略図である。
存在することで鉄の溶出が抑制され、蒸気発生器13への鉄の持込量が低減される。
させることで、炭素鋼の腐食、特に流動加速型腐食を抑制することができる。この場合の酸化チタンの必要量は5μg/cm2以上である。
食抑制効果が高まるため、腐食抑制物質の構造材表面への付着量は、5μg/cm2以上である必要は必ずしもなくなる。
図8は、本発明に係る加圧水型原子力プラントの二次系運転方法における第2の実施の形態が適用された場合における鉄溶出の水素依存性を示すグラフである。この第2の実施の形態において、前記第1の実施の形態と同様な部分については、第1図におけると同一の符号を付すことにより説明を簡略化し、または省略する。
図9は、本発明に係る加圧水型原子力プラントの二次系運転方法における第3の実施の形態が適用された場合における腐食量と腐食電位との関係を示すグラフである。この第3の実施の形態において、前記第1の実施の形態と同様な部分については、第1図におけると同一の符号を付すことにより説明を簡略化し、または省略する。
図10は、本発明に係る沸騰水型原子力発電プラントの運転方法における第4の実施の形態が適用された沸騰水型原子力発電プラントの系統概略図である。
図11は、本発明に係る火力発電プラントの運転方法における第5の実施の形態が適用された火力発電プラントの系統概略図である。
