Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent dust from being dispersed while a nuclear reactor plant is demolished.SOLUTION: A prevention method of expansion of contamination includes: a step of providing openings to a space surrounded by a nuclear reactor structure installed inside a nuclear reactor building by drilling; and a step of providing a member for filling up the space through the openings so as to replace the space with the member. The replacement is performed by injecting a filling gel through the openings into the space so as to fill one of void spaces inside the nuclear reactor building with the filling gel. 【課題】本発明が解決しようとする課題は、原子炉プラント解体時におけるダスト飛散防止を図ることである。【解決手段】本発明は、原子炉建屋内部に設けられた原子炉構造物で囲まれた空間へ穿孔して開口を設けるステップと、前記開口から前記空間を覆う部材を設けて、前記空間を前記部材で置換することを特徴とする。また、前記置換は、前記開口から前記空間へ充填ゲルを注入して、原子炉建屋内部の空間の一部を充填ゲルで埋めることで行なうことを特徴とする。【選択図】図１６
