buried object concrete electromagnetic wave exploration RC rebar severe accident
Erroneous disconnection of buried pipe in reinforced concrete that cannot be found in the Existing radar type prospecting has occurring. However, it is very difficult to solve the problem which. For this purpose, we have developed a beam focusing radar system using the phased array method. Our development system shows to can be detected the buried object without interference to the rebar....

and Dose management Head-mount-display (HMD) Maintenance work support Wearable computing
We propose a new support system at work site using wearable devices, which can navigate some task, check some drawings and communicate with remote office. In recent years, mobile devices like tablet PCs, head-mount-display or cameras has become compact enough to wear, and these have been used in work site, such as plant, factory or warehouse. In order to improve the workability and accuracy in maintenance, surveillance or patrol to be carried out in nuclear power plants, we developed the support system ...

Condition based maintenance Rotor dynamics simulation Ultrasonic vibrometer Vibration diagnosis
This paper introduces the simply applicable vibration diagnostic technique to a vertical type pump in nuclear power pla nts. This technique is the combination of simple shaft vibration measurement by an ultrasonic vibrometer and a rotor dy namics simulation. By using this technique, for vertical type pump, a simple and high-precision diagnosis is attained. It is expected that this technique has effect in cost reduction and improvement of reliability in nuclear power plants....

Condition-based Maintenance Diagnostics Motor-operated Valve Valve Performance
As use of condition-based maintenance is allowed in the new regulatory inspection system employed in Japan's nuclear pow er plants in 2009, development of advanced diagnostic technologies for motor-operated valves (MOVs) is now required. This report discusses advanced technologies in valve-setup verification, valve performance evaluation, monitoring of valve/ac tuator conditions by performance diagnostic system and moreover detection of stem crack by ultrasonic diagnostic system....
