日本原子力研究開発機構では、FaCTにおいて「高流速配管流力振動評価手法の開発」を実施し、単一エルボを持つ配管の流動状況、流体の乱れに起因する加振力及び流力振動応答を計測し、その成果により流力振動評価手法の整備、検証を進めてきた。加えて、これらの結果を反映して、単一エルボを持つ薄肉配管である1次系ホットレグ配管の流力振動評価指針を整備していくため、日本原子力研究開発機構主催の熱流動研究専門委員会の下に外部の有識者を含む大口径配管流力振動指針化ワーキンググループを設置し、指針作成に着手した。本指針(案)は、第1次案としてワーキンググループの検討成果をまとめたものである。

JAEA has been developing a flow-induced vibration methodology applied to the JSFR piping under the FaCT project. As part of this development, flow pattern in the single-elbow pipe has been investigated with the measurement of fluid force induced by turbulence flow and of the flow-induced vibration response. The experimental results have served to the development and vibration of the flow-induced vibration evaluation methodology. Based on these outcomes, JAEA has established a working group on a guideline of large-diameter piping flow-induced vibration evaluation under the JAEA's Thermal-Hydraulic Research Committee for creating the JAEA internal guideline. The first proposal of the guideline was summarized from the achievements of the working group activity. Since technical discussion has been made deeply in developing the guideline, this report summarizes technical background and understanding for the guideline.
