概要

Cables and circuits that operate full-function such as important equipment and peripheral equipment in the nuclear power plant are critical network system which can be called massive and heavyweight neural-network. We aim at the central management of information relevant to design, construction and maintenance of cables and circuits in the context of information that should be controlled are widespread as well as are required to comply with a nuclear-specific requirements such as seismic, radiation resistance and system isolation requirements. On the other hand, although not only cabling "from-to" management but also cable route (laid on what stage of cable tray etc.) management is required as a nuclear-specific requirement, the only method we implement currently is a visual confirmation which has difficulty at high and narrow places and requires massive effort to maintain planned cable route. In order to address this issue, the cabling information collection system achieves confirmation of cable route instead of relying on a visual confirmation as well as it contributes to the central management of cable relevant information by automatically collecting route information of laid cable through multiple detectors and information networks. In this section, we report on a development summary of the cabling information collection system and result of a system performance verification test that implemented on an environment of the actual nuclear power plant.
