Description
Claims (1)
- 原子力発電所における蒸気発生器の熱交換チューブ上の局所堆積物を除去する方法であって、
ホイストに接続されたマニピュレータが熱交換器内部の垂直通路に挿入され、ハイドロメカニカルマニピュレータと、旋回軸を中心に回転可能な少なくとも一つのノズルとを用い、そのノズルの向きを熱交換器の管束内のチューブ間の間隔に合わせ、マニピュレータが垂直通路内の所定の位置に一時的に固定されている間、洗浄すべき領域に対して回転するウォータージェットを放出する場合において、
蒸気発生器内部の線量率を作業場所で直接事前に測定し、その測定結果に基づいて許容作業時間を決定し、渦電流信号を測定し、測定された信号を熱交換チューブの壁面の金属の状態や堆積物の厚さを評価するために分析して、局所的な堆積物のあるセクタを探索し、洗浄セクタの座標を決定して、洗浄の時間およびモードを計算し、回転および移動可能な取り付けフレームに取り付けられ、順次移動可能なハイドロメカニカルマニピュレータを、事前に決定された洗浄セクタの座標に従って配置して、高圧ジェットの衝撃によって堆積物を洗浄するのに際し、
ウォータージェットを、1000~1500バールの供給圧力と100~150リットル/分の流量に設定し、洗浄中に洗浄ゾーンの同時ビデオ監視を実行し、洗浄終了後、渦電流信号のチェック測定を行い、得られた測定結果に従って、さらなる洗浄の必要性を判断することを特徴とする方法。
