Cable Handling Decommissioning Localization Map Matching Underwater Robot
This paper describes localization and cable handling me thod as the underlying techniques for underwater surveyrobot. Map matching method comparing cross-sectional hape data cut from a 3-D CAD with structural shapesmeasured by a range sensor is proposed as the localiza tion. The cable handling system mounted to a robot isdeveloped to operate the cable remotely. Some experime nts to evaluate performance of the proposed techniqueswere implemented at mock-ups of a reactor building and he real field. As a resu...

Array Probe Eddy Current Testing Surface Inspection Technique
Abstract An eddy current testing (ECT) system has been developed for inspecting weld surfaces of components in the reactor pressure vessel of nuclear plants. The system can be applied to curved surfaces with an ECT array probe, it can discriminat e flaws from other signal factors by using a combination of arrayed coils signal-phase. The system is applied to a mock-up of core internal components and the signal discrimination using the signal-phase clearly separated flaw and noise signals....

decontamination high-dose radiation remote-control robot rubble removal
Since the accident at Fukushima Daiichi Nuclear Power Station of the Tokyo Electric Power Company, reconstruction work at Fukushima has needed to deal with high radiation environments and has demanded new technologies. This requires the development of remote-controlled robots capable of rubble removal, radiation measurement, and other technologies, as well as ways of utilizing these technologies in tandem. It is also necessary to conduct a site survey (including the visual assessment, identification of...

high temperature lithium niobate single crystal ultrasonic transducer
Abstract Structural health monitoring (SHM) techniques are needed to maintain the reliability of power plants for long term operation. The high temperature transducers are necessary to realize SHM (monitor wall thickness of the pipings, crack growth in the materials and material evaluation) under the working condition of power plants. We have evaluated lithium niobate (LiNb03) single crystal which is well known as a high Curie temperature piezoelectric material to develop high temperature ultrasonic transd...
