- 複数の燃料棒をまとめることにより、矩形断面形状をする縦長の直方体状に形成した燃料要素(1)を、複数本、炉心内に配設してなる加圧水型原子炉の前記燃料要素(1)用矯正装置(6)であって、前記炉心の1つの空白個所に設置できるような外形寸法で縦方向に延びる1つの矯正体(8)を有し、前記矯正体(8)は、前記燃料要素(1)と同様の矩形断面形状を有するものとし、さらに、この矩形断面の4辺の側面部に配設され、かつ、前記燃料要素の側面に対向配置されて縦方向に一定の長さを有する4つの側板(14)を備えており、前記矯正体(8)の矩形断面寸法は、矯正体が燃料要素の矯正作業を実行しない休止位置において、前記燃料要素の矩形断面寸法よりも予め定めた基準値だけ小さく選定されており、さらに、前記4つの側板(14)を、矯正作業時には、それぞれ、前記矯正体(8)の休止位置から縦方向に対して垂直に変位可能に構成することにより前記矯正体(8)の矩形断面寸法を拡大可能とし、これにより、前記縦方向に一定の長さにわたって前記燃料要素を矯正可能とした、矯正装置。
- 前記基準値が16mmである請求項1に記載の矯正装置。
- 前記矯正装置の変位可能な複数の側板(14)に1つまたは複数の連結ガイド(16)が付設されており、前記連結ガイドを介して前記側板(14)は、対応する変位ピン(18)を介して矯正装置(6)に組み付けられており、前記連結ガイド(16)は前記変位ピン(18)の縦方向運動を、縦方向に対して垂直な側板(14)の運動に変換するように構成されている、請求項1または2に記載の矯正装置。
- 変位可能な前記各側板(14)に取り付けた保持板(22)にそれぞれ複数の案内溝(19)が配置されており、前記案内溝は前記矯正体(8)の縦方向に対して垂直に延び、また前記案内溝内にそれぞれ1つの対応する保持ピン(17)が係合し、この保持ピンが1つの支持架枠(7)に固着されている、請求項1〜3のいずれか1項に記載の矯正装置。
- 前記側板(14)に設けた連結ガイド(16)に、対応する変位ピン(18)が係合されて、変位ピン(18)の縦方向運動が連結ガイドを介した側板(14)の横方向運動を生ずるようにしてなり、前記変位ピン(18)は、前記縦方向運動を行なう連動手段(24)に設けた固着装置(9)に結合されており、前記連動手段(24)は、前記支持架枠(7)内に、前記縦方向運動が可能なように間隙を設けて、液圧式または機械式により運動可能であるように配設されている、請求項4に記載の矯正装置。
- 前記連動手段(24)が、前記矯正装置の縦方向に運動可能な頭部(10)と結合されている、請求項5に記載の矯正装置。
- 前記矯正装置の頭部(10)は、前記燃料要素の装入機の把持装置との互換性を有するようにするために、前記燃料要素の頭部と同一に寸法設計されている、請求項6に記載の矯正装置。
