Zusammenfassung:	To provide a blade guide which can be surely inserted in a reactor core where fuel is being exchanged, and correct inclination of a self-standing control rod in a fully inserted state.SOLUTION: A blade guide comprises: two control rod guide parts which are diagonally arranged across an intersection of a control rod in a cross section in a cross shape, and whose top ends are coupled by a coupling part. The blade guide is for correcting inclination of a control rod in a fully inserted state in a reactor core where fuel is being exchanged. The control rod guide part is a short structure, and a top end part side face is formed with a top guide knob part which interferes with a top guide for supporting the blade guide in the fuel cell and supports the blade guide in a vertical direction.SELECTED DRAWING: Figure 2 【課題】燃料交換中の原子炉炉心において、ブレードガイドを確実に挿入でき、全挿入状態の自立型制御棒の傾きを矯正することができること。【解決手段】本発明のブレードガイドは、上記課題を解決するために、断面十字形の制御棒の交差点を挟んで対角に配置され、上端が連結部で連結された２つの制御棒ガイド部から成り、燃料交換中の原子炉炉心内における全挿入状態の制御棒の傾きを矯正するブレードガイドであって、前記制御棒ガイド部は短尺構造であり、かつ、その上端部側面には、前記ブレードガイドを燃料セル内に支持するための上部格子板と干渉し、前記ブレードガイドを鉛直方向に支持する上部格子板つかみ部が設けられていることを特徴とする。【選択図】図２
