Complicated shape part Linear scanning Phased array Ultrasonic testing
Recently, an application target of the phased array ultrasonic testing (PAUT) has been extended. However, it was known that PAUT was difficult to apply to components with complex and high damping materials such as cast austenitic stainless steel (CASS). The Authors have developed shape adaptive beam forming PAUT system for complicated shape parts and comprehensive PAUT conditions analysis system for CASS. Each PAUT systems based on full matrix capture (FMC) technique. In order to enhance an applicability of...

CDF CFF ICDP ICFP OLM PRA RIDM
It is important to improve both plant safety and plant operability simultaneously in nuclear power plants (NPPs). “On-Line Maintenance (OLM)” is one of solutions for this issue. This paper proposes “Application rules of OLMs for systems & components against Severe Accidents” based on IRIDM (Integrated Risk Informed Decision Making). In this proposal, implementation of OLMs should be decided by CDF (Core Damage Frequency) and CFF (Containment Failure Frequency) under system configuration during OLM, and comp...

Charpy impact test Electron beam welding Low alloy steel Reactor pressure vessel Reconstitution method of test specimen Surveillance test
Additional RPV surveillance test are required to extend the operation license of nuclear power plants. Since the number of surveillance test specimens is limited, it is important to establish a reconstitution technique of the surveillance test specimen. Applicability evaluation of reconstituted impact test specimen by electron beam welding for RPV surveillance test were conducted, and it was confirmed that reconstituted impact test specimen was applicable to RPV surveillance test.

Deep learning Isolation Paper drawing
An electrical isolation planning system is now under development to improve the efficiency of operating and maintaining nuclear power plant. The system automates electrical isolation planning, and evaluates the influence of the isolation plan. It also equips an algorithm that automatically adds information such as circuit connection and device attribution to the original paper-drawing. A demonstration of automatic isolation planning was conducted that used actual plant drawings. The system successfully repr...

360-degree camera Patrol system Simultaneous Localization and Mapping
From a viewpoint of safe operation and the improvement in an operating ratio of equipment, Efficient maintenance engineering and inspection work is needed. Therefore, we developed a patrol system using 360-degree camera and self-localization technology. A 360-degree camera which can photo the image of all the directions was used for this system. It can record the spherical image of an inspection worker, and enables the inspection image of the direction to need. Moreover, early detection of change of an on-s...
