JOINING MEMBER AND JOINT STRUCTURE INCLUDING THE SAME
To provide: a joining member which has strength against bending stress applied by vibrations during transportation and operation of a fuel assembly, and which has airtightness for preventing leakage of radioactive nuclide; and a joint structure including the joining member.SOLUTION: End plugs 12A, 12B, 12C, 22A and 22B are formed by a base material composed of a SiC composite material at least whose surface region is reinforced by SiC fiber. An orientation direction of the SiC fiber, except for the SiC fiber that is inevitable for structure formation, is parallel to a length direction of the base material and parallel to a surface of the base material.SELECTED DRAWING: Figure 4
【課題】燃料集合体の輸送時や運転時の振動により負荷される曲げ応力に対する強度と、放射性核種漏えいを防止するための気密性を備えた接合部材およびそれを備えた接合構造体を提供する。【解決手段】端栓１２Ａ，１２Ｂ，１２Ｃ，２２Ａ，２２Ｂは、少なくとも表面領域がＳｉＣ繊維によって強化されたＳｉＣ複合材料の基材により構成され、ＳｉＣ繊維の配向方向が、構造形成上不可避なＳｉＣ繊維を除いて基材の長さ方向に平行であり、かつ基材の表面に平行である。【選択図】 図４
