AE sensor FRP hammering test non-destructive inspection
Fiber reinforced plastic (FRP) is used in a wide range of applications due to its light weight, high strength, excellent corrosion resistance and flexible processability. Although nuclear power plants may have a chance to use FRP as structural and equipment materials in the future, its radiation effect is not well known so far. Thus, we tried to evaluate its radiation degradation non-destructively using "AE (Acoustic Emission) digital hammering inspection". Two types of FRP test specimens of glass fiber and...

AE sensor cable hammering test insulating material non-destructive inspection
We reported previously the deterioration tendency of cable insulation materials used in nuclear power plants due to irradiation and the applicability of AE (Acoustic Emission) digital hammering inspection to detect the deterioration nondestructively by comparing the natural frequencies before and after the irradiation.
In this study, we selected two kinds of triple core cables which are often utilized in nuclear power plants. The natural peak frequency increased due to the increase of irradiation dose, and ...

AE sensor cable hammering test insulating material non-destructive inspection
We have researched radiation-induced deterioration behaviors of cable insulation materials used in nuclear power plants and a nondestructive inspection method to detect the behaviors in our past reports. The deterioration was generated by electron beam irradiation simulating gamma-ray irradiation in the field. As a result, we found it possible to detect the deterioration by comparing the natural frequencies of the cables before and after the irradiation through our original digital hammering inspection tech...

Acoustic Emission Sensor Efficiency Improvement Embedded Hardware Hammering Inspection
Non-destructive evaluation technique was developed to identify the integrity of embedded hardware using digital hammering inspection with AE (Acoustic Emission) sensor. The inspection can diagnose the fixed state of the embedded hardware in terms of its natural frequency and vibration duration. Mockup tests were conducted to investigate the relationship between the change in vibration duration and the fixed state under various loads including external tensile loads and thermal loads when welding supports on...
