Zusammenfassung:	To reduce the concentration of the radiation in furnace water.SOLUTION: A method for modifying a fuel assembly according to one embodiment includes a liquid creation step and an attachment step. The liquid creation step creates liquid containing at least one material of TiO, TiCl, Ti(OH), TiF, TiCl, TiN,TiC, Ti(SO), TiO, Ti(NO), AlO, Al(OH), AlCl, Al(NO), Al(SO), WO, WO, WC, WF, (NH)WO/5HO,HWO, and HWO. The attachment step causes the material contained in the liquid to attach to a surface of the fuel assembly.SELECTED DRAWING: Figure 4 【課題】炉水の放射線濃度を効果的に低減する。【解決手段】実施形態において、燃料集合体の改修方法は、液体作成工程と付着工程とを備える。液体作成工程では、ＴｉＯ２，ＴｉＣｌ４，Ｔｉ（ＯＨ）４，ＴｉＦ４，ＴｉＣｌ３，ＴｉＮ，ＴｉＣ，Ｔｉ（ＳＯ４）２，Ｔｉ３Ｏ５，Ｔｉ（ＮＯ３）４，Ａｌ３Ｏ３，Ａｌ（ＯＨ）３，ＡｌＣｌ３，Ａｌ（ＮＯ３）３，Ａｌ２（ＳＯ４）３，ＷＯ２，ＷＯ３，ＷＣ１６，ＷＦ６，（ＮＨ４）１０Ｗ１２Ｏ４１・５Ｈ２Ｏ，Ｈ２ＷＯ４及びＨ４ＷＯ５のうち、少なくとも１つの物質を含有する液体を作成する。付着工程では、液体が含有する上記物質を燃料集合体の表面に付着させる。【選択図】図４
