前回までの発表(副題1-4)では、BWR用に開発したラジオリシス及びECP評価モデルをPWR一次冷却系環境での評価に拡大適用可能であることを示した。また、両モデルの組合せにより、ECP低減の視点からのPWR一次冷却系での最適pH制御を提案した。本発表では、PWR一次冷却系での水化学制御の特徴である、B-Li連成制御に関し、本評価モデルの適用性について検討し、放射線照射下でプラント線量率抑制のための最適pH制御と構造材の健全性確保のための最適水素濃度制御の両立が可能であることを示す。

In the previous presentations (the series No.1-4), it was confirmed that the water radiolysis and ECP models developed for BWR primary coolant conditions could be successfully applied for PWR primary coolant conditions. The coupled application of both models was applied to propose the optimal hydrogen concentration control from the viewpoint of ECP suppression. In the presentation, applicability of the models to evaluation of the boron and lithium simultaneous control was discussed and it was concluded that the optimal pH control for plant dose rate suppression and the optimal hydrogen concentration control for structural material integrity could be established at the same time.
