<p>PROBLEM TO BE SOLVED: To provide the maintenance system which is improved in adaptivity in speedily inspecting, analyzing, and repairing a constituent element and make the inspecting, analyzing, and repairing operation more complete. SOLUTION: The maintenance system 1 has a network connected to a data gathering system 5, a data analysis system 6, a history file 7 for design/ inspection information on constituent elements, and a diagnostic system 8 which analyzes discontinuous structure identified by the data gathering system. The network has nodes arranged at mutual intervals and when a nuclear power steam generator is maintained, the data gathering system 5 is arranged in an area of high radioactivity while the data analysis system 6 is arranged in a safe area distant from the above area. The diagnostic system and history file 7 are arranged in the center and used in common so as to support element evaluation in areally different places. A communication through the network facilitates discontinuous and speedy evaluation, and once an inspection result is obtained, an inspection schedule can be changed.</p> |
