  • Method of managing maintenance and maintenance managing apparatus
    Patent number: 7328133
    Abstract: Structural members constructing a plant are classified into a plurality of groups on basis of a likeness criterion of a predetermined operation status. An index member having a higher degradation tendency than the structural members belonging to the group is installed at at least a part of at least one of structural member to generate an inspection plan through actual inspection of the index member to provide reduction in the number of structural members to be inspected and an extended inspection interval without decrease in reliability.
    Type: Grant
    Filed: August 18, 2006
    Date of Patent: February 5, 2008
    Assignee: Hitachi, Ltd.
    Inventors: Kenji Utaka, Kenji Araki, Kimihiro Kaimori

  • Method of treating large scale structural body
    Publication number: 20020122523
    Abstract: A method of treating a large scale structural body is provided in which when carrying out and in the large scale structural body such as nuclear reactor pressure vessel and an internal reactor structural body from and to a nuclear reactor building, a used fuel pool and fuels stored inside thereof can be protected even if the large scale structural body drops by some cause. In the method of treating a large scale structural body in which an opening portion is provided at a roof of the nuclear reactor building and the large scale structural body is carried out/in through the opening portion; the carrying out/in of the large scale structural body is performed under a condition that a protective measure for the used fuel pool is provided in a nuclear reactor well.
