PROBLEM TO BE SOLVED: To provide a method of internally inspecting a reactor pressure vessel, which allows for effectively inspecting the inside of an RPV even when it is difficult to follow usual inspection and maintenance procedures due to an accident in nuclear reactor facilities.SOLUTION: Means of clearing the above problem is a method of internally inspecting a reactor pressure vessel of a nuclear power plant, which includes a step for making through-holes through structures all the way to the inside of the reactor pressure vessel, a step for securing an access route through the structures with the machined through-holes; and a step for inserting equipment using the access route. |
