Note (General): Mechanical properties of materials including fracture toughness are extremely important for evaluating the structural integrity of reactor pressure vessels (RPVs). In this report, the published data of mechanical properties of nuclear RPVs steels, including neutron irradiated materials, acquired by the Japan Atomic Energy Agency (JAEA), specifically tensile test data, Charpy impact test data, drop-weight test data, and fracture toughness test data, are summarized. There are five types of RPVs steels with different toughness levels equivalent to JIS SQV2A (ASTM A533B Class 1) containing impurities in the range corresponding to the early plant to the latest plant. In addition to the base material of RPVs, the mechanical property data of the two types of stainless overlay cladding materials used as the lining of the RPV are summarized as well. These mechanical property data are organized graphically for each material and listed in tabular form to facilitate easy utilization of data.
原子炉圧力容器の健全性を判断する上で、破壊靱性をはじめとする材料の機械的特性は重要な情報となる。本レポートは、日本原子力研究開発機構が取得した中性子照射材を含む原子炉圧力容器鋼材の機械的特性、具体的には引張試験, シャルピー衝撃試験, 落重試験及び破壊靱性試験の公開データをまとめたものである。対象とした材料は、初期プラントから最新プラント相当の不純物含有量及び靱性レベルで製造されたJIS SQV2A(ASTM A533B Class1)相当の5種類の原子炉圧力容器鋼である。また母材に加え、原子炉圧力容器の内張りとして用いられている2種類のステンレスオーバーレイクラッド材の機械的特性データについても記載した。これらの機械的特性データは、材料ごとにグラフで整理するとともに今後のデータの活用しやすさを考慮して表形式でリスト化した。
