高速炉直管型蒸気発生器(SG)ナトリウム側3次元ポーラスボディ解析と水側マルチチャンネル解析を組み合わせた連成解析コードの整備を進めている。解析結果信頼性評価として解析コードVerification and Validation(V&V)を実施するために、評価事象における重要な物理現象を抽出する必要がある。本研究では、重要度ランクテーブル(PIRT)手法を利用してSG内部3次元伝熱流動,熱過渡,流動安定性における物理現象をリストアップし、その重要度及び知識レベルをランク付けた。そして優先的に実施すべき研究テーマを整理した。

A coupled simulation system for straight tube steam generator (SG) of FBR is being constructed which coupled the three-dimensional simulation in sodium side with the multi-channel simulation in water side. To perform the verification and validation (V&V) of simulation models, there is a need to rank the physical processes according to their importance to evaluation criterion. The Phenomena Identification and Ranking Table (PIRT) process was applied to pick up the physical phenomena inside SG for the events of three dimensional heat transfer and flow, transients, and flow stability. The ranking for relative importance of the phenomena and their current state of knowledge was determined. Then the priorities for further investigation of each phenomenon were established.
