| description | To provide a dismantlement method of a reactor pressure vessel capable of extending the option of the dismantlement method of the reactor pressure vessel.SOLUTION: The dismantlement method of a reactor pressure vessel of the present invention is a dismantlement method of a reactor pressure vessel 12 surrounded by a heat shield wall 141 and a metal thermal insulation material 142 in a reactor containment vessel 14 of a reactor building 10. This method includes: a removal process of removing the heat shield wall 141 and the metal thermal insulation material 142 from the upside; and a RPV primary cutting process of cutting the reactor pressure vessel 12 from which the heat shield wall 141 and the metal thermal insulation material 142 have been removed.SELECTED DRAWING: Figure 12
【課題】原子炉圧力容器の解体工法の選択肢を広げることができる原子炉圧力容器の解体工法を提供することを目的としている。【解決手段】本発明の原子炉圧力容器の解体工法は、原子炉建屋１０の原子炉格納容器１４内で熱遮蔽壁１４１及び金属保温材１４２で囲まれた原子炉圧力容器１２の解体工法であって、前記熱遮蔽壁１４１及び金属保温材１４２を上方から撤去する撤去工程と、前記熱遮蔽壁１４１及び金属保温材１４２が撤去された前記原子炉圧力容器１２を切断するＲＰＶ一次切断工程と、を有することを特徴としている。【選択図】図１２ |
