概要
When a crack is detected in nuclear reactor core internals, it is important to survey details of a crack. In this study, to survey nuclear reactor core in ternals simply, new electrolytic etching method that applies “Gel Electrode” and underwater microscope were developed. To apply “Gel Electrode”, we can see fusion boundary and grain boundary after electrolytic etching. To use underwater microscope, we can see surface figures of nuclear reactor core internals directly without taking boat samples or replicas that transcribe surface shape. By applying these methods, the investigation labor can be reduced greatly.
