PROBLEM TO BE SOLVED: To provide a method for housing a reactor internal structure, which can shorten the duration of the work for replacing the reactor internal structure, and which can reduce the contamination due to a radioactive substance in a reactor containment vessel when the reactor internal structure is housed in a containment container. SOLUTION: The outer periphery part of a containment container body 3 and the outer periphery part of a containment container bottom lid 4 are covered by a separable covering means (coating film S and sheet member). The containment container bottom lid 4 is disposed in a cavity 12. Water W is introduced into the cavity 12. The reactor internal structure (lower reactor internal structure part 60) is pulled up into the containment container body 3. The containment container body 3 is disposed above the containment container bottom lid 4, in the state in which the bottom part of the containment container body 3 is beneath the surface of the water W in the cavity 12. The containment container body 3 is suspended down onto the containment container bottom lid 4. The containment container the bottom lid 4 is attached to the containment container body 3. The covering means (coating film S and sheet member) covering the containment container body 3 and the containment container bottom lid 4 is separated. COPYRIGHT: (C)2004,JPO
