The time-service of nuclear accident in Fukushima is reviewed and the future subjects for various restorations are discussed. The accidents occurred by attack of the big tsunami over safety guideline following the huge earthquake. Nuclear power plants lost all of emergent electric generators and their heat decay was not removed at last. Finally, lots of radioactive material was released and peoples live near the plant site had to be evacuated. Currently, fuels melt down in the three reactors have been cooled below 100 degree C and are going toward safety end. However, there exist so many subjects for clearance of damaged nuclear plant, picking up and processing of damaged fuels, processing and manage of huge amount of waste, decontamination of and revision of safety guideline of nuclear power plants. We have to solve these subjects one by one from now on.

Although FRP is commonly used in chemical plants, there is still few effective evaluating method of the degradation of it. Ultrasonic test is the one of most common non-destructive inspection method for them, however, it is limited to find mechanical defects such as cracks or delamination, but still there are several problems for detection of chemical degradation. Novel nondestructive inspection method for an inspection of chemical degradation that is "corrosion" of organic material was studied. Chemical luminescence of degradation reaction, hyper-spectrum camera showing color tone change, and surface analysis by infrared spectroscopy with hand held type FT-IR were used and evaluated.

The word of Functional Safety derived from IEC 61508 became famous and common in the last 10 years in Japan. This KEYWORD is applied from the Railway application as chalenge project to Car components today. However the implementation prcess for the functional safety into several industries was not so easy history due to lack of understanding of their essential from the standards and the background of global market. This article expects the engineers in the future to understand the history of functional safety and to find their own solution. IEC 61508 is just an generic standards and an entrance to the world of the functional safety so that it's not perfect standards. As long as following the single standard the goal of validation of the safety product/machine/System never be completed. The most essential is to understand the comprehensive approach during Functional Safety Evaluation. The Notified Body in EU tries giving HINTS in order to establish the Japanese local laboratory/Notified Body.
